Calibration Procedures
Calibration Message
The instrument allows you to store a message in calibration memory.

You may store a calibration message for the mainframe, the DMM, the 34951A 4-Ch
Isolated DAC Module, and 34952A Multifunction Module.

For example, you can store such information as the date when the last calibration was
performed, the date when the next calibration is due, the instrument’s serial number, or
even the name and phone number of the person to contact for a new calibration.
• You can record a calibration message only from the remote interface and only when
the instrument is unsecured. You can read the calibration message whether the
instrument is secured or unsecured.
• The calibration message may contain up to 40 characters.
• Remote Interface Commands:
CALibration:STRing <string>,{<slot>|MAINframe|DMM}

CALibration:STRing? {<slot>|MAINframe|DMM}
Calibration Count
You can query the mainframe, the DMM, the 34951A 4-Ch Isolated DAC Module, and
34952A Multifunction Module to determine how many calibrations have been
performed. Note that your instrument was calibrated before it left the factory. When you
receive your instrument,

be sure to read the count to determine its initial value.
• The calibration count increments up to a maximum of 2
32
after which it rolls over to
“0”. Since the value increments by one for each calibration point, a complete
calibration may increase the value by many counts.
• The calibration count is also incremented with calibrations of the 34951A 4-Ch DAC
and DAC channels on the 34952A multifunction module.
• Remote Interface Command:
CALibration:COUNt? {<slot>|MAINframe|DMM}
