Turkey Processor Gets A Holiday Present

Our LabelBank/DataBank Rapid Bar Code Labeling System has gone into many interesting spots, but for Whitewater Processing Company, a turkey processing company located in Harrison, OH, it can almost be considered a holiday miracle. It was installed quickly by Associated Scale, an Authorized Fairbanks Scales Distributor, which meant Whitewater Processing was able to use the new system for the very busy holiday season. Fairbanks also supplied ledger web reporting software, and will be providing annual software support and remote support.

Replacing Whitewater’s handwritten system with the new LabelBank/DataBank solution improved their recording efficiency and increased production output. As an added holiday bonus, it promoted better branding for their products.

Whitewater managers recently gave the system “two thumbs up” after using it to process their holiday production load. The system includes two stations, each with a platform, an Intermec PC43d label printer, and Fairbanks Scales’ FB4000 Solution Series Instruments running LabelBank.

Associated Scale installed DataBank in a network configuration on a networked PC, along with ledger web reporting. Associated Scale also provided customized scanning and reporting software for the PC that added features to the Fairbanks Scales web reporting software. Whitewater had extremely positive things to say about Associated Scale’s service, and also praised the reliability of the Fairbanks solution.

The LabelBank/DataBank Rapid Bar Code Labeling System is an Ethernet-ready turnkey system for industrial bar code labeling, which combines easy to navigate factory-installed bar coding software with a networkable touch screen instrument and a high-speed industrial thermal bar code printer. Optional software allows users to custom format labels. The system offers virtually unlimited product information storage, remarkable data storage and communication capabilities, and a configurable backup.

The graphically-enhanced LabelBank labeling software interface features easy controls and printer communications. LabelBank comes with four commonly used box label formats designed to meet most bar code labeling requirements for boxes or pallets.

The Counting Scale Solution

Counting scales are an essential piece of technology for any business selling a large amount of product at once. When counting large amounts of small items to sell (such as nails or screws) it’s important, to be able to count them quickly and accurately. This is where counting scales come in. To count each individual piece manually takes much too long and is a massive waste of resources. With a counting scale, all of this waste is erased. As their name implies, counting scales count by weight. By weighing a known number of parts and entering that known number into the scale, the scale can divide for the precise weight of each piece, which is used to determine the accurate count of subsequent weight measurements of like parts.

The Problem

Despite their obvious superiority over other counting methods, counting scales do have one small issue that can cause inefficiency: individual items of the same kind may have slightly different weights.  Even products that are mass produced, like nails or screws, can have subtle differences in composition and size, which, of course, results in tiny differences in weight. This can lead to inaccurate piece weights if the number of pieces used to determine the piece weight is too small. If the piece weight for a product is inaccurate, all subsequent weights recorded by the scale could be slightly off. This effect is negligible when counting small numbers of pieces, such as 10 nails. But when counting hundreds or thousands of pieces of one product, these slight differences in weight can make a significant difference.

The Solution

The problem described above can be solved by using a larger sample size. Basic statistics states that the difference between pieces contributes less to the overall average when more pieces are measured at once. A large sample size reduces the effect of non-uniform weights between pieces, which ensures a more accurate piece count and in turn reduces overall counting error.

Using a large sample size to find your piece weight for any product can take a long time, however, as manual counting is still needed initially. This is where Fairbanks Scales’ technology enters the picture.

Fairbanks Scales’ Omega Counting Scale

Products like Fairbanks Scales’ Omega Counting Scale (OCS) and Product Look Up (PLU) software make using large sample sizes feasible. Our scales can store information electronically; piece count weights can be measured once and stored, rather than weighed again each time a new count must be taken. This drastically reduces the time needed for each count. Our Omega Counting Scale can store hundreds of piece weights with the help of the PLU manager software, so every product and its associated information can easily be accounted for.

It all comes down to the larger sample size, which is only a practical solution when using modern counting scales such as one of Fairbanks Scales’. Once a company can consistently use these larger sample sizes in their measurements, their accuracy will be drastically improved, and overall efficiency will be increased. As long as the Fairbanks Scales Omega Counting Scale is in the picture, counting inefficiencies need no longer cause stress or worry.

A web interface for your truck scale will improve your invoicing efficiency—and eliminate those annoying trips out to the scale in the rain and snow.

I can’t say enough positive things about web interface technology for truck scale instruments. Remote access using your existing Ethernet infrastructure is a breeze, so it’s a mystery to me why relatively few companies have adopted it. What it costs in dollars will quickly be made up for by faster invoicing and getting a better handle on the resources you need to get a job done.

Yes, I know some people call it simply a “nice to have” convenience factor to have immediate access to scale data. And yes, it may be difficult to quantify the return on investment for a web interface. But if your invoicing is based on transactions and you need to know how much has been delivered, a web interface is essential.

Efficiency and convenience

Being able to remotely access your instrument to obtain transaction data is a real boon to efficient operations. You can reach into your instrument directly from your PC and get a report immediately. No more getting up from your desk, walking to the scale (which can be in another office in the same building or down the street next to the scale), manually printing out a report, and then inputting the information for analysis. No more taking a stack of tickets and sorting them by hand. And no more trudging through the snow and ice to get the information you need before trudging back.

Instead, with remote web interface you get information in a file that can be opened directly in your spreadsheet program and analyzed any way you want. With a few clicks, you can determine the total number of transactions and who the high volume customers are. You can get the information to answer any transaction-related questions without having to shut down the instrument and take away from your scale productivity.

There are other methods of course, but they all have limitations and inherent restrictions that hinder their usefulness. Serial communication methods are hampered by distance limitations.  For example, the RS-232 standard for serial communication transmission of data only works within a distance of 50 feet.  Plus, with RS-232, the speed at which data can be accessed is also limited. A web interface avoids both of these restrictions, allowing for remote access at network speeds.

What do you need to get the benefits of web access?

To fully realize the benefits of web access, you are going to need an operating Ethernet network infrastructure, including a local area network (LAN). If you want to communicate among different physical sites, you will need a wide area network (WAN). But, if neither exists, there are still inexpensive ways to provide a stand-alone private network between your PC and the scale instruments.

So, all in all, it is easier and faster to use a web interface to get your data from your desk on your PC instead of trooping out to someone else’s workspace to do part of your job.

The Fairbanks FB2550 instrument offers this type of web interface. In addition, customers can update their customer files, product files, and stored tare weight files remotely from their desk using the web interface, instead of pushing buttons on the instrument. Another side benefit is that Fairbanks technicians can log in to the scale instrument with a tablet or PC and perform diagnostic checks, troubleshooting and even calibrations and configuration tasks.

Celebrating 50 years with the World Ag Expo

One of the shows I love to be a part of is the World Ag Expo, which is celebrating its 50th anniversary February 14-16, 2017 at the International Agri-Center in Tulare, California. World Ag is the largest annual agricultural exposition in the world, with more than 1,500 exhibitors and 2.6 million square feet of exhibit space.

It has something for everyone, from displays of the latest in farm equipment, communications, and technology, to free seminars on topics important to dairy producers, farmers, ranchers, and agribusiness professionals. Members and attendees are constantly looking for the best practices to keep the industry healthy, strong, and growing just like their products. And such a bargain – just $15 per attendee.

By the looks of it, this year’s World Ag Expo seminar program is focusing more and more on new technology to help farmers compete. The seminar called Mapping Drones in Precision Ag: How to Get Started, caught my eye. Experts from a major global commercial drone company will discuss agricultural-based drone use, especially how mapping fields can benefit farming operations.

Another seminar, Global Opportunities for U.S. Manufacturers in a Rapidly Changing World, is something I know agricultural businesses will benefit from. The experts will discuss how U.S. agribusiness must develop innovative export marketing strategies to help them survive in today’s world market.

Other seminars that caught my eye from an equipment point of view include those on irrigation tools and techniques, water issues, and the rise of mechanization.

Of course, Fairbanks Scales will be on hand to show off what we bring to the table — or should I say what we bring to the field — for the agricultural market, including products that improve sanitation audit scores and increase overall food safety. We will have our Talon line of heavy-duty Truck Scales, Aegis Floor Scales, sanitary design QuickSilver Stainless Steel Platforms, and the 1124 Series Portable Utility Scale. Drop by Booth #D2/E1 to take a look.

While they may not be as sexy as a drone, scale equipment for agricultural operations can have a major effect on the bottom line. For example, we recently helped one Tennessee hay farmer select the right scale for his business – a scale that can withstand the farm’s challenging weather conditions and maintain safety for his employees, while also allowing him to collect the data he needs to help him double his production in the near future.

We are excited about all the innovations in the agricultural industry and look forward to participating in the World Ag Expo as it celebrates a half-century of progress. We’ll see you there on February 14th!

Improve Efficiency and Accuracy in Counting Applications – Know How to Maximize Your Counting Scale

In any business venture that sells vast amounts of product at a time, fast and accurate counting methods are essential. The smaller the product and the more items processed at once, the harder it is to keep track of accurate counting. This can waste time in man-hours, and money in incorrect counts. In the past there wasn’t much to be done about these problems. But today’s new technology can handle what the old could not. Here are some ways to make sure you get the most accurate and efficient count from your counting scales.

When counting large amounts of small items (such as nails or screws) it is important to be able to count them quickly and accurately. Counting by hand is time consuming and subject to human error. Counting scales use the weight of a known number of parts to calculate the weight of each piece. This weight can then be used to determine the count of subsequent weight measurements.

When using counting scales, there are two common problems that cause inefficiency: inaccurate piece count weights and the fact that accuracy can be affected drastically if the parts counted are not exactly the same weight.

Often there are small differences in weight from piece to piece. This effect is negligible when counting small numbers of pieces, such as 10 nails. But when counting 100s or 1000s of one product, this effect is exacerbated and can cause significant miscalculation. Any miscounting causes problems for a company. Undercounting shortchanges the customer and causes customer dissatisfaction. Overcounting shorts the company, causing consistent loss of profit.

Inaccurate pieces count weights cause similar problems by not getting an accurate weight for the individual pieces in the first place. The initial mistake spreads to each subsequent count and can cause major miscalculations before it is caught and corrected.

Both of the problems described above can be solved by the same solution: larger sample size. The larger the sample size, the more accurate average weight can be measured. Basic statistics states that the difference between pieces contributes less to the overall average when more pieces are measured at once. This both ensures a more accurate piece count weight and reduces the effect of non-uniform weights between pieces.

At one time, counting scales were expensive, and if companies wanted this type of accuracy they would rent scales once or twice a year for periodic inventory. Fortunately today’s scales are affordable to own and are able to make taking large sample sizes worthwhile for companies that use counting scales and software.

Products like Fairbanks Scales’ Omega Counting Scale (OCS) and Product Look Up (PLU) software make using large sample sizes more feasible than in the past. Now that counting scales can store information electronically, piece count weights can be measured once and stored. Taking the time to carefully weigh a large sample size in the beginning will increase overall accuracy, and will eventually pay for itself in profits that were previously lost due to miscounting.

It all comes down to the larger sample size. Modern counting scales provide companies with a method of using larger sample sizes in measuring piece count weights without losing money to extra man-hours. Once companies can consistently use these larger sample sizes in their measurements, accuracy is drastically improved and overall efficiency increases. All of this saves companies time and money, and helps make their operation run smoothly and reliably.

Tips for scale calibration – Follow these best practices to ensure scale accuracy

Scale accuracy depends on the way a scale is used and cared for. Weather, use, and wear can change the accuracy of a weighing device, which is why periodic calibration is so essential. Here are a few tips to help you minimize losses from a poorly calibrated scale.

Before listing my suggested tips, I want to make sure readers understand just how much seemingly minimal errors can cut into profits over time. Take the Acme Aggregate Company example shown below, in which two hundred pounds may appear miniscule, since a typical truckload of sand or gravel can exceed 80,000 pounds. However, when one does the math, the truth is revealed – an annual revenue variance of about $345,000.

acme-aggregate
#1 – Select the proper calibration frequency   

The proper calibration frequency is based on two factors: the requirements of law and the value of the commodity – In other words, how critical is the accuracy of the weighment? Yes, calibrate more often for copper than manure, or if the weight is critical to a process (like for batching, mixing or recipe work). Also calibrate more frequently if the scale is under a mixer or agitator with a lot of vibration, because that is more likely to drive the calibration out of bounds.

Most people typically calibrate their scale once a year, just before the state certifier rolls into town to verify the weights on a scale. I really recommend at least twice a year; and consider even more frequent calibration if you have high value commodities or high volume applications. If being off by 20, 40, or 60 pounds makes a big difference to the bottom line, consider monthly calibration, with spot checks in between.

# 2 – Conduct calibration using state-certified test weights

An established scale service company typically has its entire inventory of test weights tested and certified annually, in accordance with state weights and measures standards.

Beware of service companies that test only a portion of their overall weight inventory each year. Preparing the weights and delivering them to a metrology laboratory for testing requires an enormous amount of time and money, so it may be tempting for some service companies to skip this important step. All too often, weights may be condemned and un-certifiable. Start by verifying with your service provider that their weights have been certified.

# 3 – Service before calibrating

You will save yourself a lot of headaches by scheduling regular service with an authorized scale calibration firm just prior to state inspection by weights and measurements personnel. Avoid the real risk of red tagging, when the state inspector says the scale is so far out of bounds that it can’t be used for business until it’s remedied.

# 4 – Select a reputable calibration service company

Set up your periodic routine calibration plan with a reputable calibration service company. And make sure the company conducts the inspection in accordance with NIST Handbook 44 regulations for commercial weighing applications. A simple drive over and a sticker will not suffice and could be a total waste of money and time.

It is also important that your service provider uses a professional test report process that performs the NIST calculations without the service technician having to perform them. The best systems are application based and reduce test reporting errors ultimately supplying the scale calibration report without human errors.

calibration-test-cart

# 5 – Make sure the calibration follows key steps

Using a truck scale as an example, the scale company should conduct the calibration this way:

  1. Drive over the vehicle scale with a specialized test vehicle looking for repeatability.
  2. Unload a specialized certified weight cart that will travel over each section to ensure all sections weigh exactly the same.
  3. Drop onto the scale up to 25,000 pounds of certified test weights for a final calibration test.

# 6 – Collect the proper documentation from each test

The scale owner should always ask their service provider to provide:

  1. Service provider’s Weights and Measures License number.
  2. Copy of certified test weight documentation for conformance and traceability.
  3. Information on licensed technicians performing test.
  4. A written test report that covers:
    1. Equipment specifications
    2. Section test readings
    3. Overall calibration with “As Found” and “As Left” readings
    4. Maintenance or Acceptance tolerances used
    5. Whether the scale passes or fails

New packing line equipment helps produce supplier improve revenue

We recently helped North Carolina produce supplier, Corey Produce, with weighing issues that “cropped up” after they established their own packing facility. The company had been sending sweet potatoes and watermelons to be packed elsewhere, but decided to cut out the middleman last year. The Robersonville, North Carolina farm was using a simple (but inaccurate) eyeballing method to fill boxes. To ensure it did not short its customers, Corey wound up overfilling the boxes and shorting itself instead!

The new facility ships in two box sizes: a 40 pound carton box and a 500 kilogram (1100 pound) box. In a bulk line, the sweet potatoes are washed, graded, and sized. As they are sized, workers fill up the 40 pound carton boxes, “guesstimating” their weight and then putting on the lid.

For this application, Fairbanks recommended that Corey install a Fairbanks Series III general purpose bench scale with built-in rechargeable battery and integral pillar-style instrument. A roller ball top was recently added to this popular scale, so workers never have to pick up the boxes.

Operators placed the Series III bench scale with roller balls at the end of their conveyor line. They fill the 40 pound carton box and slide it down the scale. The scale will weigh up to 150 pounds in increments of .05 pounds. If the box weighs more than 40 pounds, operators remove potatoes to get as close the target weight as possible. The scale is used with a large 1-inch backlit LCD display enabled with auto shutoff timer and an RS232 serial interface.

For the first six months, Corey packed the large 500 kilo boxes, visually estimating the contents, filling them up to the top to make sure each box held more than the required amount. They knew they would be giving away some product, but wanted to make sure there was at least a little extra. Most of the sweet potatoes are being exported to the Netherlands, so they felt it was important there be no question of accuracy.

After six months of “guesstimation,” they began to be concerned they were really shorting themselves. After all, each box could be off by as much as 20 kilos (44 pounds), so they were potentially giving away about 1000 pounds of sweet potatoes in each 25-box shipment!

For this application, Fairbanks recommended the use of an Aegis 4-foot by 4-foot, 5,000 pound industrial mild steel floor scale. The scale is equipped with an FB 1100 Series instrument, which comes with a highly visible 2-inch backlit LCD. The instrument is mounted on the wall above the scale. It can sit on the forklift, so when the box is set, operators can see what it weighs from the forklift.

Corey says that instead of packing 520-540 kilos per box, they can now get it down to about 503-504 kilos, just enough overage to ensure they meet the required weight. They estimate that removing the excess paid for the cost of the floor scale in about one week.

This year Corey also began packing watermelon in a separate packing facility within the same building and purchased new scales for this operation. The watermelons are fed down a long belt, past brushes that clean off the sand from the field. After that they go down another long belt with seven scales that are used to weigh them and separate them into three different sizes, which makes it much easier to ship the sizes required by specific customers.

In addition to supplying the scales, Fairbanks also handles setup and calibration. This has proved to be a great benefit to Corey, especially given the rigorous scale calibration process required by the food safety audit they have to conduct for watermelon and sweet potato operations. Fairbanks also performs calibration once a year before the sweet potato and watermelon seasons start just to check the scales and make sure they are ready for the season.

LabelBank / DataBank software is not just for the food industry – read on to see how it helps with labeling and tracking bags of currency

Tracking boxes, crates, and bags of product is important to most businesses, but it’s especially important in the currency business! Recently, a leading armored car business asked us to help them develop a better process for labeling and tracking bags of money. They wanted to improve the accuracy and verification of bagged currency and aid in compliance with government regulations.

We suggested that they look at the LabelBank/DataBank Rapid Bar Code Labeling System. The industrial bar coding system for data acquisition, bar coding, and labeling combines user-friendly, factory-installed software with a networkable touch screen instrument and high-speed industrial thermal bar code printer. Optional software allows users to custom format labels. The system, widely used for food labeling applications, is crossing into virtually every industry.

Armored vehicles need to verify weight of loose coin bags

The armored car company provides armored transportation to the Federal Reserve Bank, commercial, and bank customers. When processing bags of loose coins, they verify bag weight by denomination, which allows them to catch any bags that are not the declared value and minimize the variance to the end user.

The company did not have a way to properly label processed bags with all of the information required. They were looking for an automated system that gets the right information on the label, so they could speed up the process and eliminate human error. The bags need to be verified for deposit by denomination to be within a specified weight tolerance. They also must be labeled with the bank name, ABA routing number, denomination, and dollar value. If the information on the bag is not complete or correct, the armored car company was liable for any variance from the declared value on the bag.

Fairbanks Scales immediately started investigating the process. We identified the key personnel and the required methods and processes. In addition to a system that could guarantee accurate weighment, record the data into a database, and label the product with an approved label, the company really wanted to reduce human error in counting the quantity of bags. They also needed immediate access to the information gathered.

After reviewing the requirements, we determined that the LabelBank/DataBank Rapid Bar Code Labeling System was the optimal solution. LabelBank allowed the armored car company to uniquely identify each bag of currency for their customers with an easy to understand label. It also helps them offer additional services, including customized labeling and immediate data reporting. DataBank provides a solid platform for storing and integrating the data collected with third-party applications.

The system also includes a secure override function, which can be used to authorize approval of an out-of-tolerance condition. The function immediately alerts the company to any errors, and records the error, along with the authorizing override account for traceability and measurement.

The system brought a new level of efficiency and compliance to the company’s operations. It streamlined their weighing process, and is helping them provide a level of service unmatched by anyone in their industry.

So, LabelBank/DataBank is not just for food, but it’s a tasty solution nonetheless.

Don’t give contaminants a place to hide! — My top 4 sanitary design tips for weighing equipment

Every day it seems there is another story in the news media about companies that have to recall their products due to some type of harmful contamination. A few recent notable examples that spring to mind include an E coli scare from ground beef, a 500 million egg recall due to a Salmonella scare, and of course the death of 23 people from Listeria in cantaloupes.

That’s why I am so passionate about the need to use weighing equipment designed using the sanitary design principles issued by the American Meat Institute’s Equipment Design Task Force. It’s the only way to make sure we reduce food product contamination risks throughout the complete process – from producer to consumer.

The Task force worked with equipment manufacturers, certifying organizations and government officials to develop guidelines to reduce the risk of contamination of food products by pathogens.

Identifying sanitary principles can be an enormous task with each industry having a different perspective.  I have listed The Ten Principles of Sanitary Design that have been identified by the AMI. They are:

  1. Cleanable to a Microbiological Level
  2. Made of Compatible Materials
  3. Accessible for Inspection, Maintenance, Cleaning, and Sanitation
  4. No Product or Liquid Collection
  5. Hollow Area Should be Hermetically Sealed
  6. No Niches
  7. Sanitary Operational Performance
  8. Hygienic Design of Maintenance Enclosures
  9. Hygienic Compatibility With Other Plant Systems
  10. Validated Cleaning and Sanitizing Protocols

 

While developed for the meat industry, the guidelines apply equally well to equipment for all food uses.

 

The use of stainless steel construction is a critical part of sanitary design for scales – but I’ve observed that many scale manufacturers consider this to be the only important factor in the overall design. Here are my top four sanitary design tips for scaling equipment:

# 1 – Cleaning accessibility

All parts of the equipment must be readily accessible for inspection, maintenance, cleaning, and sanitation without the use of tools. Make sure you have quick and easy access to clean floor scales to prevent debris build-up and bacterial growth. This includes access to any tight spots that may harbor unwanted material or bacteria. Equipment should be free of niches and recesses to allow for proper cleaning procedures. Look for equipment that minimizes gaps and eliminates bacteria-harboring areas, like lap seams, protruding edges, inside threads, and bolt rivets.

For example, we designed the Aegis Lift Deck floor scale to give quick and easy access to clean in and around the scale. The QuickSilver platforms are also designed to be easily cleaned.

#2 – No product or liquid collection

Make sure your equipment is self-draining so liquid does not accumulate, pool, or condense on the equipment. Maintenance enclosures and all push buttons, valve handles, switches, and touch screens should prevent penetration or accumulation of food, water, or product liquid. Also, enclosures should be sloped or pitched to avoid their use as a storage area.

#3 – Hermetically seal all hollow areas

Be sure to eliminate or permanently seal hollow areas, like frames and rollers, whenever possible. For example, bolts, studs, mounting plates, brackets, junction boxes, nameplates, end caps, and sleeves should be continuously welded to the surface—not attached via drilled and tapped holes.

#4 – Select the right load cell for a food-grade environment

Selecting the right load cell is crucial to ensure accuracy and performance, especially in a food-grade environment. The internal components of the load cell contain electronic circuits that require protection in a wash-down environment. For example, Fairbanks Scales uses stainless steel construction and hermetically sealed components in load cells to prevent entry of moisture and other external contaminants into the body of the load cell.

A good scale maintenance program pays for itself – make sure your program includes these five components

An accurate scale is an essential tool for any company whose revenues are based on the weight of goods entering or exiting a facility. Without scale accuracy a company can lose thousands, if not hundreds of thousands of dollars annually. On the other side of the equation, annual maintenance costs for a truck scale run anywhere from $1,000 to $3,000. If one compares that to the potential cost of weighing errors, most users find that a good scale maintenance program more than pays for itself; oftentimes it also pays for the actual cost of the scale.

To be most effective, a scale maintenance program must have five key components:  use of a state-licensed service provider; conducting calibration using state-certified test weights with written calibration and test report for proof of accuracy; a thorough testing process; visual inspection services and minor repairs; and thorough reporting. Here’s my take on the key aspect of each component.

Use a state licensed service provider

A commercial scale company cannot certify a scale – only the state weights and measures organization can do that. But the commercial company has the authority to recalibrate and reinstate an inaccurate scale that has been “tagged-out” by the state, as long as the scale company is state-licensed and registered in good standing. So make sure the commercial scale company you are using shows you their valid license.

Use state-certified test weights for calibration

An established scale service company typically has its entire inventory of test weights tested and certified annually, in accordance with state weights and measures standards. Beware of service companies that test only a portion of their overall weight inventory each year.

Make sure testing process is thorough

The test should start by determining the length of the platform and the total number of sections along that length. (A scale section is where there is a load point, also called a load cell or strain gauge). Load points are where weight is transferred from the load to the scale and where scale accuracy is maintained. It is critical that the accuracy of each load points is maintained, so as weight is applied, it is transferred evenly. If a load point or section fails a strain test, then it must be calibrated to conform to requirements by making a mechanical or electronic adjustment.

Incorporate visual inspection and repairs

A thorough scale maintenance program must include regular visual inspection, followed by any necessary repairs of issues found. The visual inspection should include scale condition, regulatory conformance, signs of damage and debris buildup, safety, clearance, corrosion, and any electrical conditions. A good service company should conduct a free visual inspection be able to perform any minor repairs while on-site for the maintenance visit.

Thorough reporting

Every maintenance inspection should include a written report documenting test results, and including both before and after calibration, as well as a summary of finding and recommendations.
