Why does my scale keep changing? #1 Every time a digital scale is moved it needs to be calibrated. Initializing the scale resets the internal parts allowing the scale to find the correct “zero” weight and ensure accurate readings. If the scale is moved and you do NOT calibrate it, you are likely to see fluctuations in your weight.
