CALIBRATION
When to calibrate
Calibration may be required when it is initially installed, if the scale/balance is moved to a substantial distance. 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 may occur.
How to calibrate
1.
Before entering calibration mode,
