Keithley 2000 Calibration Manual

Programming calibration dates
Program the present calibration date and calibration due date by sending the following com-
mands:
:CAL:PROT:DATE <year>, <month>, <day>
:CAL:PROT:NDUE <year>, <month>, <day>
For example, the following commands assume calibration dates of 12/15/95 and 3/14/96 re-
spectively:
:CAL:PROT:DATE 1995, 12, 15
:CAL:PROT:NDUE 1996, 3, 14
Saving calibration constants
After completing the entire calibration procedure, send the following command to save the
new calibration constants:
:CAL:PROT:SAVE
NOTE Calibration constants will not be saved unless the :SAVE command is sent.
Locking out calibration
After saving calibration, send the following command to lock out calibration:
:CAL:PROT:LOCK
