GSE 375 - Exiting Calibration; Analog Output Calibration

65
FALSE ZERO
False Zero calibrates the Model 370/375 without removing the current gross weight. This is
particularly useful in tank weighing applications where it may be both time consuming and costly
to completely empty the tank. This operation is achieved by establishing a false (temporary zero)
zero reference. Test weights may then be added to verify calibration. The zero reference
determined during the last calibration is not affected.
