Function Generator Calibration; Programming Calibration Dates; Saving Calibration Constants; Locking Out Calibration - Keithley 2015 Service Manual

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
