B-16 Calibration Reference Model 2750 Multimeter/Switch System Service Manual
Model 7700 calibration commands
Table B-4 summarizes calibration commands for the Model 7700 plug-in module. Note
that CARD1 commands calibrate the card in Slot 1, while CARD commands request cali-
bration count, date, and reference temperature information from a card in Slot 1 through
Slot 5.
NOTE A Model 7700 must be installed in Slot 1 through a Model 7797 calibration/
extender card to be calibrated. See Section 2, “Model 7700 calibration.”
