Caution
and ADGAIN, must be used only by
qualified service personnel, and only
after replacing A/D converter components. Improper A/D
calibration may render the indicator unusable.
The CLEAR EEPROM function erases both A/D and load
cell calibration data. The A/D converter and the scale
must be recalibrated after using this function.
