How to calibrate a digital scale without weights
There are many ways to calibrate a digital scale, but this article will show you the easiest and least expensive way to do it. You can use these steps to calibrate any type of precision measuring device like micrometers, meter sticks, rulers, etc.
The CALIBRATION PROCESS:
1) Weigh a container filled with water and record that weight
2) Weigh the container on a scale you want to calibrate and record the value, do this several times.
3) Calculate the average of your recorded values, if it is a small number like 5 or 10 weigh at least 10 times, but if it's a larger number like 100 weigh at least 100 times and record the average.
4) Subtract your recorded value from the average of your recorded values by dividing (average - recorded). The result is the difference in weight and it's what we will use to calibrate your scale.
5) Weigh a container filled with water and add 0.5% of your difference in weight calculated earlier to the new weight.
6) Subtract this new value from your recorded value and you have calibrated your scale.
How to calibrate a scale with household items
There are a few household items you can use to calibrate your scale. One is a piece of paper, which you can use to measure the weight of an object. Another is a set of known weights, which you can use to calibrate your scale.
To calibrate your scale with a piece of paper, place the paper on the scale and note its weight. Then, measure the weight of an object that you know the weight of. Compare the two weights and adjust your scale accordingly.
To calibrate your scale with known weights, place one of the weights on the scale and note its weight. Then, place another weight on the scale and note its weight. Compare the two weights and adjust your scale accordingly.
Repeat this process until your scale is calibrated. Keep in mind that different scales may require different calibrations. If you're not sure how to calibrate your scale, consult the manufacturer's instructions.
