8.2.2 Calibration Commands
The following group of commands directly or indirectly affect the accuracy of
the instrument. These commands should only be used by qualified, authorized
personnel. Calibration parameters can only be changed if protection is dis-
abled by entering the proper pass-code using the command *pas= ddddd.
Entering an invalid passcode or cycling the power re-establishes protection of
the calibration parameters. The parameters can be read without disabling the
passcode protection.
