How to Tell If a Digital Scale is Accurate

How to Tell If a Digital Scale is Accurate [Seven Step]

How to Tell If a Digital Scale is AccurateThe function of a digital weight scale is to weigh anything from a pin to a ton of bricks or anything else.

While you are on diet or doing an experiment as for that you need to mix some chemicals then the necessity of a digital scale is very important for you.

If the weight is less by a gram or some ounces then the perfection of your diet, as well as your experiment or whatever important thing that you are doing, will be ruined before you can figure out what has gone wrong in diet or experiment.

So that, you need to check that the accuracy of your digital weight scale is right or wrong.

To justify the accuracy, this article will provide you with much detailed information that you needed the most to calibrate your digital weight scale correctly in order to get the most accurate reading.

We are going to divide this article into two major parts which will provide you the most important information that you need.

From the first section, we will know that how to calibrate your weighing scale, and in the second section, we will discuss the four important things that you to know about your digital scale.

Step 1: Weigh Some Weights

An accurate weight is very important otherwise the digital scale will never be correct. A box containing a product that weighs one pound does not have an accurate weight, sometimes it could contain more or less than one pound.

If the product is made from plastic or metal then we can accept the weight of that product.

Many stores of hardware have products like this. If you know that the weight of your product is exactly one pound then you can test the weight of your product on a digital scale.

In order to do that you need to turn on your digital scale so that it can warm up and get ready for you to measure the weight.

After the scale is fully warmed up you can put the object in the center of your scale in order to weigh the product. Give it some seconds to measure the weight accurately and you should wait for the final result.

If the scale shows you to one pound then the reading of this scale is accurate.  And if it doesn’t show the exact reading that you are expecting then you might have to calibrate your digital scale.

Step 2: Scale Calibration

To calibrate your scale you need to remove the weight from the scale and turn off the power. You need to turn off your digital scale in order to give it a reset.

After resetting turn on the scale and you need to find the button that calibrates the scale the button could appear in a variety of number as follows:

  • Function
  • FUN
  • CAL
  • MODE
  • LG
  • KG


If this button doesn’t appear on the front then it must be located on the back part of your digital scale. In order to find it, you must turn over the scale and search for a small hole.

You can insert a paperclip or a pin in order to enter the function mode of the digital scale. Press the right button and hold it down for a while.

After some time the screen of your digital scale will be changed and for the most scale will show the three things given below:

  • 0
  • 000
  • CAL

If this symbol appears then you are in the calibration mode of your scale. Some other scales have other variations.

Step 3 – Calibrate Digital Scale

Now the scale is ready to place the weight into it. Let the weight of the product remain in the same place for at least 5 seconds.

Once the scale has weighted the weight, hold down the calibration button the display will read “0,” “END” or “CAL ” After the symbol showing up on your digital scale you should turn it off.

After 30 seconds you can turn the scale back on and now the scale be calibrated.

The four things you should consider keeping your digital weight scale to be safe:

1. Scale Misreading:

Sometimes your scale might not show the exact reading that is expecting or sometimes it happens to see that a digital scale is showing different reading from each every time you trying to weigh something.

This might happen due to mechanical problems or having load cell problems. In order to solve this kind of problem scale register weight and then return to the “000” display when the object is removed.

You can test your scale by weighing free weight. If the scale is not showing the exact free weight then your digital scale might need a reset or calibration. Many digital scales have calibration system that allows you to reset and check your digital scale.

2. Different Readings:

Depending on the variation of some calibration of digital scale. Different types of digital scale show different types of reading.  In order to get the exact reading, you need a well-calibrated digital scale.

If you have a Digital scale of your own then you might consider yourself calibrating it after every month or three weeks. However digital scale can show different types of reading when it has a damaged cell that has been not used for many days.

This can happen if the cells may have been shock-loaded. Another possible thing that your digital scale might give you inaccurate reading when it is overloaded.

3. Unstable Readings:

Some digital weight scale does not give steady results which means the scale has an electric malfunction within the digital indicator. Some digital scale referred to as drifting which is is the light reading while the object is on the scale.

You cannot depend on this if you want the precise reading. Low humidity causes a static buildup on the load cell and weight controller. With the changing of the humidity the static charge in the air also changes.

Your digital weight scale might have some small changes in input voltage can a static discharges which can cause the weight reading to drift a little bit.

4. Low Readability:

Display readability on the scale is referred to as the scale display readout that is hard to see. Having the display burned out or having some power issue from the power source can cause display readability.

If you have some financial help then you can change the battery or the power source cable which will help you a lot. By following these steps you can rule out simple malfunctions and you can help yourself without having a broken scale.

Also, shifting scales from environments with different temperatures can cause temporary inaccuracy and also cause some damage to the internal mechanisms.

Many of the devices are manufactured to be more resistant to endure harsh conditions. Be sure to check your scale if it is suitable for your uses.
