Keithley 2010 Service Manual

Programming calibration dates
Program the present calibration date and calibration due date by sending the following
commands:
: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
respectively:
:CAL:PROT:DATE 1995, 12, 15
:CAL:PROT:NDUE 1996, 3, 14
NOTE If an incorrect date is sent, an error will be generated.
Saving calibration constants
After completing the 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
