Keithley 2015 Service Manual

Calibration 2-23
Function generator calibration
1. Connect the rear panel SOURCE OUTPUT jack to the front panel INPUT jacks (see Fig-
ure 2-6.)
2. Send the following command to complete function generator calibration:
:CAL:PROT:FGEN:STEP1
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 12/15/97 and 3/14/98
respectively:
:CAL:PROT:DATE 1997, 12, 15
:CAL:PROT:NDUE 1998, 3, 14
Saving calibration constants
After completing the calibration procedure, send the following command to save the new cal-
ibration 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
