10.0 AUTO CALIBRATION

• Calibration may be required when the balance is initially installed
or if the balance is moved from a location.
• With time and use, mechanical deviations may occur. Therefore
calibrate the balance whenever the best accuracy is required or
when any deviation is observed during weighing a test weight.
• Before calibrating it is necessary to have the proper calibration
weights. The weights should be OIML Class M1 type or better.
If you do not have proper weights do not attempt calibration.
