R ESET C ALIBRATION
Cal Reset may be necessary when an over-load or under-load condition exists, preventing the
completion of the calibration process. Calibration Reset adjusts the zero and gain factors of the
A/D amplifier to factory default values for maximum sensitivity.
After performing a calibration reset, a complete recalibration is required. The effects of a
calibration reset do not take effect until the Model 370/375 recalibrated and calibration information
has been saved.

If Code 02 (under-load) or Code 03 (over-load) is displayed during calibration, press [CLR] to
perform a calibration reset.
Reset Calibration Gain Factors Example (370):
1. From the Weigh Mode, press [ZERO] + [SELECT].
