Calibration
When to calibrate
If the scale is inaccurate, calibration may be desired when the scale is first set up for
use, or if the scale is moved to a different altitude or gravitation. This is necessary
because the weight of a mass in one location is not necessarily the same in another
location. Also, with time and use, mechanical deviations can occur.
How to calibrate
Note: calibration value must be 100KG that you have set.

If calibration is repeatedly incorrect then: 1) Replace the batteries, 2) Try a more stable
surface or vibration and interference free location.
