There was a time when weighing scales were made up of two plates, a central pole, and a beam. These days most scales are now digital given the advancement of technology. Arguably, it is probably easier to fix the balance type scales rather than to learn how to repair digital weighing scales.
No one can deny the usefulness of a weighing scale as it is a tool used for both businesses and at home. In fact, many people consider the digital weighing scale as an investment either for their health or their business. And since it is an investment, ensuring that it works all the time and that it will last long become essential. Thus it is best to know and learn how to fix a digital weighing scale.
Keeping It Away From Trouble
One of the best ways of ensuring that the digital weighing scale remains functional for a long time is to take care of it. And looking after the tool starts even before the actual purchase.
When buying a digital weighing scale, think first of its storage. Where would you place the unit? Will it be inside the bathroom where it is likely to be exposed to moisture? What will be the room temperature of the location of the weighing scale? How much space is available for it? Will it be near any objects that could fall off the shelf or rack easily?
These are some of the questions that you would have to think about before buying the digital scale. If for example, you intend to place the unit in the bathroom, it is best to get one that has a higher tolerance for moisture. If space is an issue, and then consider getting a smaller one than a bulkier type.
Keep in mind that correct storage of the unit is also crucial in prolonging the life of any digital weighing scale. Some units are more sensitive to temperature changes compared to others while others are more durable despite exposure to extreme temperatures.
Additionally, there is the concern about the moisture as some digital scales are more tolerant of humidity while some products can hardly take moisture.
Dust is another issue. After purchasing a unit, make sure that the scale is placed in an area where it less likely to accumulate dust. If the entire area is prone to dust, take some time to wipe and clean the digital scale regularly. Do not underestimate what dust can do to any gadget or tool as in many cases being exposed to so much dirt can result in an irrevocable damage to any device.
It is also necessary not to use the tool as a storage place for any object. This means that items must only be placed on the scale if they are being weighed.
Periodic Calibration Is Key
A digital weighing scale is useless if the scale is inaccurate. This is the reason why the balance of the device must always be calibrated.
To ensure that the digital weighing scale will last for a very long time, make the necessary periodic calibration as it is the best way to know whether the device is still functional or not. For example, if the weighing scale still does not reflect the correct weight after several times of calibration, it means that the tool is already malfunctioning. When this happens, do not hesitate to call for some repairs from the qualified professionals.
Testing the Scale
In many cases, one suspects that the digital weighing scale is malfunctioning when it fails to provide the weight accurately. You can start the troubleshooting by testing the scale if you suspect that the device’s accuracy has been comprised.
Find an object to test the scales. It is essential to use an object with a known weight to verify the accuracy of the scale. For example, one might use some dumbbells to find out if the weighing scale is still providing an accurate measurement. Place the object, like the dumbbells, at the center of the plate to ensure a correct measure.
If for example, one placed a 30-pound dumbbell at the device, and yet it only reads 27 pounds, then it is safe to assume that the scale is no longer providing the correct information. Testing the scale can be done again following the same process and guidelines above to double check the accuracy of the tool.
How to Repair Digital Weighing Scale? Adjust as Needed
Digital scales are accurate in most cases. But sometimes, the scale is a bit off. Perhaps you have noticed how the digital weighing scale no longer reflects the correct weight you place on it. If this is the case, then an adjustment is needed.
Often people get confused over adjustment and calibration. Many tend to use the two terms when it comes to their scales as if they are synonyms. The truth is they are not as they are two completely different terms.
The words “adjustment” and “calibration” when pertaining to the use and maintenance of weighing scales are technical terms. And to put them in layman’s language, adjustment relates to the changes or modification one does to the scale. On the other hand, calibration is about how the device behaves and whether it is at par with the standards for which it was set.
But this is not to say that calibration is not important when troubleshooting a digital weighing scale. On the contrary, it is an integral part when one is trying to determine how to repair a digital scale.
Calibration of The Balance
Do not worry as the calibration process for digital weighing scale is relatively simple. Just follow the instructions from the product manual, and the calibration will be done in no time. In case the manual is no longer available, then you can do it yourself.
Turn on the digital scale first and wait for a few minutes before doing the calibration. Digital weighing scales are in a way like vehicles wherein you would have to warm it up before using it.
Get some weights for calibration. It is necessary to get objects that have a defined weight as one needs accuracy when doing the calibration. After finding objects or weights then it is time to proceed with the calibration.
Press the calibration button to start the process. Place the weights on the scale, but make sure that these objects are located at the center of the weight’s plate. No part of the object should be hanging on the side of the scale as such a position will fail to measure the weight accurately.
Now, wait for the device to determine the weight of the objects and then press the calibration button once again to end the whole process. The display of the scale will show either of the following: “End,” “Cal,” or “Calibrate.”
The Batteries May Be The Culprit.
Incorrect reading of the weights is not the only problem that one may encounter with digital weighing scales. Sometimes we may be experiencing some difficulties in the use of this device because of other reasons.
For example, the display screen may be showing some faint numbers, or perhaps it takes a longer time for the device to turn on, these could mean that the problem may be because of the battery.
Sometimes, the battery has already drained out and is already in need of a replacement. If there are problems one encounters with the digital weighing scale, then it is also best to start by checking the batteries or replacing them all completely.
Many of the digital weighing scales on the market these days have indicators to show whether they are already running low on battery. Always pay attention to the indicators or buttons of the scale as they make the life of the user easier. It also helps if one takes the time to familiarize him or herself with how the entire weighing scale works before putting it to good use.
If the device is still giving you the same problems despite replacing the battery, check the battery terminals. Sometimes these terminals end up being bent that they no longer touch the battery thus providing no power at all to the device. One might also consider checking if the cell was placed correctly to ensure that it is working correctly.
The Plug Can Be The Problem
Be prepared to check some things if the digital weighing scale runs on power.
For one, it is possible that the problem does not lie with the scale itself but rather the sockets to where it is plugged in. In checking for this, unplug the device and look for another outlet to plug it. If the issue with the scale persists despite using a different outlet, and then it is the unit itself that may have a problem.
The next step is to check for the cable. Are there holes in the wire? If yes, then this might be the problem. Try to recall if there had been incidents where the cable could have been possibly damaged as it could be the reason why the scale is giving the user or owner some problems.
Just a fair warning about checking the electrical component of the scale; a device that runs on electricity could blow a fuse. Be careful in handling and testing the plug and the electrical part of the weighing scale as nobody should tinker unnecessarily with electrical stuff.
Checking the LCD
If the LCD seems to be giving some faint readings, then the display could be the problem. Sometimes the connector is just a bit off or loose, and in which case, one might apply some gentle pressure on the LCD. But do take note that gentle pressure should be applied. Sometimes, pushing the LCD too strongly might do more harm than good.
Do not bang the LCD or the entire device against a hard surface as doing so could result in damage that might require the user to replace the whole weighing scale instead of just doing some minor repairs.
Going Back to The Manual
It is also a good idea to get the manual of the weighing scale out and take some time to read it again or first the first time. Keep in mind that each product, including measuring devices like scales have their differences.
The manual can provide plenty of information about how the product works. The product manual is always a right place to start looking for tips and answers on how to repair digital weighing scale.
If the hard copy of the manual that came with the product has been lost, one can search the internet for a copy. Asking the manufacturers for a copy is also an option if the product manual is not available on their website.
Trusting The Right People
If the problem persists despite following the instructions above or those found in the manual, it might be time to seek the help of a professional. Sometimes the issues one encounters with digital weighing scales are due to some manufacturing defect that would be handled by the repairmen of the product maker.
Check if the scale is still under warranty. If so, then bring the product to the service shop or call the manufacturer’s customer care line or the number provided on the warranty card. However, if the scale is no longer under warranty, then it is still best to have the item checked by the manufacturer’s service professionals or service centers. One will have to pay for the services since it is already out of warranty.
Knowing how to repair digital weighing scales can be very handy if one wants the tools to last long. Arguably, fixing a digital scale is reasonably easy. In cases where problems persist despite attempts to repair them at home, it is also a good idea to seek the help of the manufacturer or other qualified professional to get the scale to work again.
