CALIBRATION
The XC780 has two modes of calibration; Quick cal and calibration setup. Quick
calibration is used to recalibrate the scale during service maintenance or
routine checkup. Calibration Setup is used when first connecting a new scale
platform to the XC780. As all internal scales are pre-calibrated at the
factory, only Quick cal will be used in most situations.
Some of the keys have alternate functions during Quick Calibration and
Calibration setup:
PRINT:
The print key is used to select the currently entered
item value and advance to the next item.
TARE:
The TARE key is used to used to select the currently
entered item value and back up to the last item.
SCALE SELECT:
The SCALE SELECT key is used to select from the
options available for each item.
SHIFT/CLEAR:
The SHIFT/CLEAR key is used to return the value of the
item to its default setting.
RESET:
The RESET key is used to exit calibration.
The J3 jumper on the XC780 logic board is used to lock out entry into the
parameter and calibration setup modes. Placing a jumper plug on J3 will lock
out entry into the setup modes, removing the jumper enables access.
