Top 5 Scale Problems and How to Fix It

For the many businesses that use a scale in any part of their daily operations, that scale is a crucial part of the process. When it is not functioning properly, not only can it severely disrupt your production line, but it can lead to a lot of unwanted aggravation. 

There are a few common problems that can often be fixed with some minor attention. However, it should be noted that before doing any troubleshooting on your own, you should consult with your supplier or manufacturer as this could void any warranty you may have. 

Pharmaceutical Plant Workers Using Scale

Below are the top 5 scale problems and how you can fix them. 

Scale Problem #1: Lack of Power

Most scales require electricity to run. So when the scale doesn’t power on or it doesn’t seem to have any power at all, it may not be connected. And while it could be any number of issues, checking the power source is a good place to start. Make sure that it is securely plugged into the outlet. 

Many times these cords accidentally get unplugged and simply require you to plug it back in. However, if it is plugged in and you are still facing a lack of power, then you may want to take a moment to check for any frayed wires or damage to the cord. Any visible damage to the power cord could result in power issues — and may be a fire hazard. 

If you don’t see any cord damage, test the power supply of the cord, the outlet, and the adapter. This should help you to narrow down the faulty area. 

Scale Problem #2: Inaccurate Readings

Calibration is so important when it comes to getting accurate readings on scales of all types. And, at a minimum, it should be done every year. If this is something you haven’t done in a while, perhaps your scale is not calibrated and can explain your inaccurate readings.

Follow your manufacturer’s instructions for calibrating your specific scale. Once you do, test the scale to make sure the reading is correct. If it isn’t, then it could be another issue, such as having a broken component within the scale. 

At this point, it is best to speak to a scale expert at your supplier or manufacturer to determine the issue. 

Scale Problem #3: Inconsistent Readings

You rely on your scale to give you consistent readings. If you find that it isn’t, there could be a couple of reasons why. 

Drifting refers to a scale that fluctuates with its readings due to water exposure. If your scale is used in or near water or has been exposed to rain or floods, you could be dealing with drifting. If exposed to water, load cells, cables, the junction box, and other areas of the scale can be affected. Turn it off until it has a chance to dry out. 

If there is no way that water is the culprit, perhaps you are experiencing electrical issues or even have loose connections. Double-check your wires and cords and make sure everything is secure.

Scale Problem #4: Battery Problems

Some scales run on batteries. And while having no power can alert you to batteries that are likely dead, sometimes there can be issues with displays blinking, taking too long to display a weight, or doing other strange things. This could be the sign that your batteries are getting low, but aren’t quite dead yet. Or, there may be a battery leak inside the scale. 

Try replacing your batteries with a fresh batch and see if that makes a difference. 

Scale Problem #5: Error Codes

Error codes were designed for manufacturers to help you troubleshoot issues with the scale. If you have your manufacturer’s manual, each error code should be listed so that you know what it means and how to address the problem. 

If you don’t have your manual, a quick search on the internet can often lead you to a list of manufacturer codes.

How Do I Troubleshoot a Pallet Scale? (Floor Scale)

YOUR TROUBLE SHOOTING GUIDE FOR INDUSTRIAL FLOOR SCALES

Pallet scales typically take a lot of wear and tear every single day. Some of it is expected and some of it goes overboard. Of course floor scale users are supposed to “place” or “set” pallets on the scale platform. However, in the real world “placing” is usually somewhere between outright dropping and slamming.

Also, in addition the the shock loading many floor scales often take everyday, the scales are often utilized in harsh environments such as outdoors, recycling centers, food processing centers, etc… In fact, floor scales are often subject to high pressure washdowns, corrosive materials, overloading, hazardous areas, and much more.

That’s why it’s important to have your platform scale checked periodically on a consistent schedule. We can help you with that! Ask us about our Service Agreements that we offer. 

However, even with the best scale maintenance program, weighing equipment can fail between scale inspections.

So, is there anything you can do to troubleshoot your floor scale? 

Actually, there are several steps you can take. Below is a list of floor scale troubleshooting tips to make sure your industrial floor scale is working correctly. Keep in mind, if you try the list below and your floor scale still isn’t working, you will need to contact our scale repair department by calling (919) 776-7737

how do I troubleshoot my floor scale?

HOW DO I TROUBLESHOOT A FLOOR SCALE?

PROBLEM
Any floor scale related problem

POTENTIAL CULPRIT
Anything

SOLUTION
Unplug the power from the scale for a minute and then plug the power back in after a minute or so. It seems too simple, but you’d be surprised how often this works.

 

PROBLEM    
Floor scale not reading correctly

POTENTIAL CULPRIT
Could be something under the weighbridge, weighbridge shoved against a wall, bent foot, cut cable, etc..

SOLUTION
This may take a few minutes of your time but it might save a service call. Look for anything under the scale platform. Make sure the platform is not shoved against a wall or pit frame. Make sure all four feet are in good shape and solidly on the ground. Make sure the homerun cable has no obvious cuts. If that doesn’t work, it’s best to call our service department.

 

PROBLEM
Pallet scale display either shows all “- – – -” or is constantly displaying different numbers

POTENTIAL CULPRIT
This could be a cut cable. This could also possibly be a bad load cell. 

SOLUTION
Examine the cable. If you see a cut, it might be a good idea to replace the cable. If you see nothing wrong with the cable, you might try disconnecting the load cells in the junction box, one by one and see if that calms the system down. If that works, you might have a bad load cell(s).  If that does nothing, you might have an indicator issue.  At this point, you probably need to contact the scale service department so that our factory trained scale technicians can get to work and have you back weighing again.

 

FLOOR SCALE TROUBLESHOOTING ADVICE

The good news is that we stock many of the replacement scale parts that are needed for floor scale repairs. We have replacement shear beam load cells in many of the capacities you may need like 2.5k or 5k.  We have summing boards that are used to connect all the load cell wires.

How to Buy a Counting Scale

Counting scales are great tools for speeding up your productivity since they can accurately provide you with two measurements at one time — the weight and the quantity of the items. You can measure multiple parts at once, such as nuts, bolts, screws, coins, etc. and every single piece will be accounted for – even the smallest of parts. 

What’s more, counting scales can digitally collect all of your data so you will no longer need to manually track your numbers. Not only does this make your counting process more efficient, but it makes it much more accurate, too. 

If you are in the market for one, then you need to take a look at a couple of factors that will help you determine just how to buy a counting scale. 

Determine Your Average Piece Weight

Before you can find the right counting scale, you need to calculate your Average Piece Weight (APW). Yes, counting scales measure a batch of items, but they need to know the weight of each piece to determine the number of items in a collective weight reading. 

The APW is the number you want to confirm your counting scale will calculate – especially since these numbers can be small.  

Many counting scale manufacturers will list a Minimum APW  within the specs of the product. So, for instance, if your screws weigh .02 lbs each, then you will want to make sure the specs include at least this amount – and greater.  

 

The Capacity Level

Counting scales measure a batch of items all at once which is what makes them so useful. When looking for a scale that will work for your needs, you must make sure it can handle the bulk load of items – not just the individual piece we measured above. In other words, you aren’t just measuring the weight of one screw, but rather a batch of screws. The scale needs to be capable of handling both weights. 

Look for a counting scale that will allow you to use a batch that doesn’t surpass the maximum capacity supported. Keep in mind that overloading a scale can cause damage internally and may cost you in the long run. 

 

Adequate Pan Size

Different types of counting scales have different pan sizes. Bench style counting scales can offer you different pan sizes so you can find what will work best for you to gain an accurate measurement. However, please note that there is not much variety in the size of pans on most compact counting scales. 

When making your purchase, take into consideration the size of the batch of units you are measuring – and the container that is housing them. This will need to sit freely – and entirely – on the pan. 

 

Automatic Recording of Data

One of the perks of having a counting scale is that you will no longer need to manually record an accounting of your measurements. Instead, you will find the ease of automatic recording. If this is of interest to you, be sure that the scale you choose is one that is user-friendly and able to connect to a PC or other device for data recording. 

Pay attention to the details of the scale and what is required of the PC to make sure the two will work together. If you have any questions, you should ask before making your purchase.

Shopping for Scales on the Internet Based on Low Price

Everyone Loves a Great Deal

Just about everybody considers “price” to be a very important part of their buying decision. We’ve actually discussed this concept of price versus quality on this blog many times over the years. The challenge is that sometimes the line is blurred between quality and low quality. Many of us frequent discount stores looking for deals whether it’s a great deal on a shirt, tools, exercise equipment etc… Bottom line, almost all of us look for ways to save money while still getting a great product!

Cheap Scales Sometimes Cost You More Money…

The digital scale that you find on Amazon or ebay for $75 can display weight. It might even be fairly accurate but the quality and durability of this item is often not in the same league as top scale brands like Avery Weigh-Tronix, Ohaus, or Rice Lake. And, often we hear stories of how certain scales are thrown out and replaced fairly often.  In this blog post, we will discuss a few of the areas of concern that can occur when shopping for scales on price alone.

Greater Long Term Costs

With many of these scales, the enticing part is the low up front cost.  Many of these “overseas manufacturers” cut corners in design and construction. This often leads to low quality, higher failure rates, and often scales that are just either inconsistent or non-reliable. 

Here’s the big point…. once these scales fail, these cheap components are often impossible or impractical to repair. So, you now have to buy another new scale. If you choose the same type of product, you will likely have the same result or perhaps you could run into stock issues with some of the overseas products. 

On the other hand, high-quality scale manufacturers design weighing equipment for relatively simple maintenance. Since scale service companies stock parts for most major scale brands, downtime typically lasts only a few hours. Generally speaking, when you purchase reputable brands of scale equipment, you often enjoy significantly lower lifetime costs (and less downtime) despite the initial higher price.

Accuracy?

The whole point behind purchasing a scale is to measure weight accurately, right?  The challenge is finding the right scale that will consistently display accurate weight at a price that you can afford. The truth is that cheap weighing equipment often can’t deliver consistently accurate results. Many of the cheap scales that you find online are not capable of passing a NTEP evaluation and earning a certificate of conformance (aka… legal for trade) often due to poor repeatability. 

What’s the point of weighing items if the numbers are inconsistent or incorrect entirely?  These errors can lead to things like bad batches and/or lost dollars. Now, factor in the benefit of having a reliable and accurate scale that produces accurate batches and consistent weights in buying & selling environments. 

Anytime that we do a blog post about this subject I always think about the Pennsylvania 7600 counting scale. Sure, you can buy a cheap counting scale online or in the shipping supplies catalog that’s priced anywhere from $100 and up.  The problem is that usually the lower cost counting scales are about 99% plastic and 1% aluminum.  And they typically don’t last too many years.  Or, you could just buy a Pennsylvania counting scale and feel fairly confident that it’s going to be around for at least a couple of decades.

4 Tips To Avoid Costly Maintenance for Your Large Industrial Scales

Scales are the backbone of any business, and key to the quality and marketability of your products. However, improper care of your scale can lead to inaccuracies and even severe damage over time. To avoid expensive maintenance costs, there are few methods you can use to ensure your scale is both long-lasting and accurate.

1. Get Your Scale Calibrated Regularly

Proper calibration is the best sign that your scale is functioning properly. Wear and tear, particulates, and working conditions can all cause your scale to become inaccurate, affecting your bottom line. The calibration process can be time-consuming, so it is best to hire a scale calibration service to check your scale for you. Professional services will use certified known weights, as well as go through the certification of your scale with the state.

2. Have a Professional Service Make Preventative Repairs

One of the best ways you can avoid major damage to your scale is to hire a professional service for a tune-up. A licensed professional will be able to make small repairs that will extend the life of your scale, as well as notice any warning signs of chronic wear or damage that you may have missed. Many companies offer specialized scale repairs, including careful testing of load cells, moisture levels, and wiring. Having a scheduled service for your scale is both convenient and less expensive overall.

3. Install Your Scale Correctly

Did you know that the main cause of damage to scales comes from installing them in the wrong location? Getting your scale set up professionally will optimize workflow and keep your scale safe from contaminants and needless wear. Many companies can partner with contractors to create custom setups or pits for your scale or make specialized screening for additional protection. Installation is also the perfect time to certify and calibrate your scale and establish a healthy relationship with your repair technician.

4. Know When You Need to Replace or Upgrade Your Scale

Many large industrial scales are made to last through constant day-to-day use. However, even the best scales cannot last forever. Knowing when to seek out a new scale for your business will avoid issues in the future, as well as keep your company up to date with the latest technology and standards. Many older mechanical scales can undergo conversion into electronic ones by replacing the weighting beam with a load cell. The process can bring new life to your equipment as well as avoid manual errors while on the job.

What Are the Different Types of Load Cell Cables?

Responsible for channeling both power and communication between the load cells and the indicator, load cell cables are an integral part of building a custom scale. Though not just any cable will work. See, load cell cables are selected based on the distance between the two parts, as well as certain environmental conditions like temperature, contact with abrasive or flammable materials, or even rodents. 

Container truck on scaleBefore you can know the right type your custom scale project needs, it is best to have an understanding of the different types of load cell cables available. 

4-Wire Load Cell Cable

Perhaps the most common cable, the 4-wire load cell cable is used primarily for short distances. As its name suggests, this type consists of four wires: 

  • Power (excitation) +
  • Power –
  • Signal (output) +
  • Signal –

Once connected, the cable should run from the scale to the indicator display. These wires are calibrated and designed to handle the surrounding temperatures. Many custom scale projects use the 4-wire load cell cable since it is more affordable and suitable for most scales. However, should you need additional length or if your scale is in an unpredictable environment, you may need to reconsider the type of load cell cable you are using. 

6-Wire Load Cell Cable

Designed for longer distances and more difficult settings, the 6-wire load cell cable offers a lot more options. Again, as the name suggests, these load cell cables have six wires. They contain the four found above, as well as positive and negative sense wires. The long distances that 6-wire load cell cables cover can subject them to changes in resistance, temperature, and dips in voltage. The addition of these two sense wires helps to keep things flowing steadily.

Because they are not thermally compensated as the 4-wire load cell cables are, the 6-wires can be cut and used alongside other cables with no issue – making them perfect for larger commercial custom scale projects. 

Types of Load Cell Cable Shielding

While 6-wire load cell cables offer a lot of benefits when designing a project, it is important to note the surrounding environment and opt for shielding that will protect the cable from any outside environmental factors. Below are the most common types of load cell cable shielding.

Hostile Environment Cable

Hostile environment cable is best used in environments that are, well, hostile. Depending on where the scale is being used, the cables may come in contact with harsh or abrasive substances, such as fuel, ether, or even salt. Over time, these substances can damage the cables. 

Hostile environment cables are created with a polyurethane jacket that acts as a barrier against these damaging substances, keeping the cable safe and the scale running smoothly. 

Rodent Protection Cable

Rodents and their incessant chewing may seriously interfere with a scale’s functionality. If in an environment where there are rats, mice, or other pests, the load cell cable may become enticing – leaving you with hefty costs to replace some or all of the cable.

Rodent protection cable is a type of cable that protects against this pesky situation. The outside layer of the cable is a braided shield making it difficult to chew. And, as an added defense, it is coated with a chemical that will discourage them from wanting to ever take a second bite. 

Intrinsically Safe Cable

Flammable gases or liquids or generally hazardous materials can be damaging to load cell cables, requiring added security in the form of a jacket. For intrinsically safe cables, industry-standard blue double jackets are used to protect the cables from exposure to these dangerous materials. 

High-Temperature Cable

In environments where the temperatures fluctuate or reach extreme highs, load cell cables need an outer covering that will protect the wires regardless of how hot it gets. A high-temperature cable is designed with a fluorinated ethylene propylene (FEP) jacket that insulates the wires and can withstand the heat without getting damaged. 

Choosing the Right Load Cell Cable

Choosing the right load cell cable is important. If you would like to learn more about the different types of load cell cables or have questions about what would work best for your project, contact our sales department at (919) 776-7737. After all, at Central Carolina Scale, we have the largest inventory of load cell cables in the industry. 

What do you think? Airlines Might Weigh Passengers…

Subject: Aircraft Weight and Balance Control

Airlines could soon require some passengers to step on the digital weigh scale or provide their weight before boarding the airplane.

The initiative, which was described in a recent Federal Aviation Administration (FAA) advisory, attempts to provide new data on average passenger weights as the current numbers allegedly don’t reflect today’s higher obesity rates in the US. By adding this requirement, this would help aircrafts not exceed their allowable weight limit. Essentially, the FAA wants to determine how much heavier Americans have gotten over the past decade. 

If this becomes the new standard, the new mandates would require airlines to take surveys to establish average passenger weights for crew members, airline baggage and passengers.

Once they’ve chosen a traveler, an operator may determine the actual weight of passengers by having them step on a scale before boarding the aircraft. However, if that’s not an option, they’re urged to ask each passenger their weight, while making sure to add 10 pounds to account for clothing.

Of course when it comes weighing people in a public setting… privacy needs to be considered, which is why the FAA also provided guidelines on conducting the procedure in a way that protects passenger privacy.

They stipulate that the scale readout should remain hidden from public view while an operator should ensure that any passenger weight data collected remains confidential. Travelers have the option of declining to participate in any passenger or bag weight survey, per the guidelines.  You can read much more on this subject by viewing the original article

What do you think about this subject?  I guess it makes sense as long as the airlines do a good job with privacy and being discreet.  However, what happens if you total up all the passenger and baggage weight and it’s too much?  Are certain people asked to leave?  Well, whatever you need regarding this subject, we can provide you.  Bench Scales to weigh airplane passengers, Airplane Baggage Scales and more…   

 

Why Should I Consider a Truck Scale with Weigh Bar Weight Sensors inside?

Should I buy a truck scale with weigh bar sensors? The Avery Weigh-Tronix Weigh Bar® was designed to overcome the shortcomings of the traditional strain gauge load cell and to provide the end user with a rugged, highly reliable and linear load sensing device at reasonable cost.

More than twenty years of extensive use in industrial, farm and transportation applications has demonstrated that the Weigh Bar has met these requirements. The unique, robust design of the Weigh Bar is the primary reason for this success.

The Weigh Bar has proven itself over the past 20 years to be one of the world’s most robust weight transducers manufactured today with over 500,000 installations world-wide.

The IP67 Weigh Bar design provides inherent strength and overload protection, while also providing accuracy and high reliability. A significant contributor for this is the positioning of the gauges on the outside of the Weigh Bar. More robust than a shear beam load cell for a given output – a shear beam load cell will reach its peak fatigue point much sooner than a Weigh Bar.

Error Reduction

The unique design of the Weigh Bar allows simple calculations to be made by the indicator, eliminating several types of errors:

End Loading – When an end load is applied to the Weigh Bar, it is subjected to a
uniform compressive strain throughout its length – all sensors detect the same strain.
Torsion Effects – When torque is applied to the Weigh Bar, a uniform torsional shear strain is developed through the length of the bar – both sensors detect the same strain.
Side Loading – When a side load is applied to the Weigh Bar, it acts as a beam, but at a 90-degree angle. When this occurs, the neutral axis of the beam (the point in the beam where neither tension or compression occur) falls directly under the center of the strain gauges. No apparent strain is seen by the gauges.
Vibration –The fine grain structure of aircraft quality steel is resistant to vibration fatigue and induced error. The strain gauges and adhesive used are also vibration and fatigue proven.

Load Cells – The Avery Weigh-Tronix Weigh Bar® Weight Sensor

The exclusive Avery Weigh-Tronix Weigh Bar® is an extremely rugged, highly reliable, load sensing device. Over several decades, the Weigh Bar® has built a reputation for precision, reliability and durability that no other load cell can match.

Weigh Bar – Reduced cost of ownership 

Precision machined from aircraft quality, alloy steel, the Weigh Bar® offers excellent repeatability and long-term durability, reducing cost of ownership and need for load cell replacement.

Rugged Weight Sensors

With up to ten times more steel content than shear beams or compression cells, it absorbs impact to minimize peak forces and is virtually fatigue-proof. The Weigh Bar® is proven to resist electrical surges and is protected by a limited warranty that includes coverage against lightning damage.

Accurate Weigh Bar

The sensor’s design automatically cancels the effects of side loading, end loading and twisting, resulting in quick, accurate readings which are achieved regardless of temperature change, vibration, and shock loads on the scale.

Sealed “Load Cell”

The standard alloy steel Weigh Bar® is well protected against harsh environments by an exclusive 5-layer, sealing process. For the most challenging locations hermetically sealed stainless steel weigh bars are available.

How Do You Calibrate a Scale?

Scales are an essential tool for your business. Over time, scales can be subjected to wear or exposure to damaging elements, leading to errors and losses in accuracy. These malfunctions can result in further issues down the line with your shipments and products and should be addressed as soon as possible. Scale calibration is the process of restoring your scale’s accuracy through recording, testing, and maintenance.

What is Scale Calibration?

The calibration process starts with a standardized weight being placed on your scale. This is repeated several times in order to make an accurate record of your scale’s performance. The reading your scale gives will determine whether it matches the known weight, is within the calibration tolerance range, or so inaccurate that it immediately needs repairs. The calibration tolerance range is a measure of a scale’s ability to accurately measure weight within commercial guidelines. This differs slightly from the instrument range of the scale and is designed to give it optimal performance during regular use.

Why Does My Scale Need to be Calibrated?

Outside of wear or potential damage, there are other reasons why you may need your scale calibrated. If your scale has been in use for a long time, checkups are a healthy way of preserving its function for an even longer period.  Scale measurements are also affected by travel and altitude, providing slight variations depending on where the scale was made or if it was used before reaching you. What is known as factory calibration is not as reliable as it seems! Having your scale calibrated by a trusted local professional is key to ensuring consistent performance. A licensed professional is the only way to have your scale pass state inspection and keep its registration, a requirement for commercial work in many states.

How Often Do I Need To Calibrate My Scale?

There are a few things to consider when deciding how often to get your scale calibrated. The manufacturer’s guide is the first place you should look. All scales come with a suggested calibration frequency that is worth taking note of. How often you use your scale is another factor. Consistent use of any scale will cause inaccuracies, so you may need to have it calibrated more often if it used day in and day out. If the scale is used in an environment that may cause damage it may require even more care. Areas that can cause malfunctioning include those that are dust-filled, electrically charged, or prone to oil spills. Lastly, if your work or business requires highly accurate measurements it may be worth investing in the optimal care of your equipment. Keeping your scale in top form can prevent costly mistakes and setbacks in the future.
