How to Calibrate Your Digital Weight Scale

A digital weight scale is one of the easiest tools to use with regards to measuring weight. In fact it is much easier to read a digit than a wobbling dial. However, as with all scales, digital weight scales need to be calibrated every few months so that they can keep on reading accurately. Most digital scales come pre-calibrated from the manufacturing company, but by time and with use and handling, its reading can drift slightly.

By following a few straight forward steps, you will be able to calibrate your digital weight scale. In order to complete this task effectively, make sure to place the scale on a stable, firm surface and that there are no strong air movements near by.

Step 1 – Preparation

Before attempting any calibration routine it is always important to turn on the digital weight scale and let it warm up. Moreover, it is also important to use only objects of which you know the weight for your calibration routine. It is useless to have an approximation when you are aiming to get precision.

Step 2 – Starting Calibration Mode

Locate the calibration button of the digital weight scale. It generally carries one of the following prints: “Cal”, “Function”, “Mode” or “Cal/Mode”. Now press this button down until the digits displayed on the scale turn into “0”, “000” or “Cal”. At this point, the scale should be in calibration mode.

Step 3 – Placing the Calibration Test

Once the digital scale is in calibration mode, you can place the objects of known weight which you have gathered in step 1. Ideally you should put on the digital weight scale a number of objects that amount to roughly 30 pounds so that the scale has a balanced weight to calibrate on. Make sure that you place the 30-pounds objects in such a way that they not wobble or move. Also make sure that they are placed in central part of the scale and not at one edge of it, in order to ease precise readings.

Step 4 – Calibration

At this point allow the digital scale to take in the measurement. There is no need to wait for much since this will only last round-about five seconds in all. Now you can press the Calibration button once more to end the calibration session. Once the session is over you should have one of the following words displayed on your digital scale’s monitor: “End”, “0” or “Cal”. Most modern digital scales reset automatically after calibration is finished. If this is not the case, at this point you are advised to switch off your scale and leave it switched off for at least two minutes.

Through these few simple steps you would have completed your digital weight scale calibration. Once you switch on again your digital weight scale you can rest assured that the scale will read accurately your next weigh-in.
