For this key to function, you must first set the weight calibration flag ON. Press *99 to observe flag status. Press * to toggle flag ON or OFF. With flag set ON, press EXIT.
Since the bin, even when empty, weighs about 1300 grams, it is necessary on initial setup of equipment to instruct the controller of the exact tare weight of the empty bin.
Slight drift in the tare or zero weight during day to day operation is normal. All weight calculations automatically compensate for this drift. However, when the bin is empty, if the weight displayed is more than 50 grams above or below zero, then you may wish to reset the electronics to display zero when the bin is empty.
If, when the bin is empty, the weight displayed is greater than 100, or less than
If weight readings drift steadily in one direction, allow system to warm up before setting ZERO or FULL weights.
Generally, when zero weight shifts, full weight reading shifts the same amount. Since resetting ZERO WT automatically shifts FULL WT the same amount, resetting ZERO weight usually is all that is necessary to correct both ZERO and FULL weights.

AGAIN, both FULL WT. and ZERO WT. have been set at the factory. A drift of several grams from these settings is normal and should not be of any concern. Recalibration should be considered only if ZERO is more than 20 grams off or FULL WT. is more than 50 grams off. These errors do not prevent proper proportions from being dispensed. ZERO error is always "tared" for proper weighing of each component. FULL scale error will only cause accumulated totals to be off by the degree of this error. The primary function of
