CALibration:COUNt?
Syntax
CALibration:COUNt? [{<slot>|MAINframe|DMM}]
Description
This command queries the instrument to determine how many calibrations have been performed on the entire mainframe, the digital modules, or the internal DMM. Note that your instrument was calibrated before it left the factory. When you receive your instrument, be sure to read the various counts to determine the initial values.

For a more detailed discussion of the calibration procedures, see the Agilent 34980A Service Guide. Please refer to that guide before attempting to calibrate the instrument as improper use of the CALibration commands can adversely affect the accuracy and reliability of the instrument. |
Used With:
34951A Isolated DAC Module
34952A Multifunction Module (DAC channels only)
Internal DMM

Remarks
The calibration counts increment up to a maximum of 4,294,967,295 after which they roll over to "0". Since the value increments by one for each calibration point, a complete calibration may increase the value by many counts.
The mainframe calibration count is incremented by the CALibration?, CALibration:MODule? (the mainframe must be unsecured; see CALibration:SECure:STATe OFF command) and CALibration:POINt? commands. You can read the calibration count whether the instrument is secured or unsecured.
The internal DMM calibration count is incremented by the CALibration? command. You can read the calibration count whether the instrument is secured or unsecured.
The 34951A calibration count is incremented by the CALibration:MODule? command (the mainframe must be unsecured). If the mainframe is secured, the calibration count will not be incremented.
The 34952A calibration count is incremented by the CALibration:POINt? command. If the mainframe is secured, the calibration count will not be incremented.
If the specified slot (CALibration:COUNt? <slot>) does not contain either a 34951A or 34952A module, an error is generated.
The calibration count is stored in non-volatile memory, and does not change when power has been off, after a Factory Reset (*RST command), or after an Instrument Preset (SYSTem:PRESet command).
Return Format
The command returns the calibration count indicating how many calibrations have been performed.
Examples
The following command returns the calibration count on the entire mainframe.
CAL:COUN? MAIN
Typical Response: +1048592
The following command returns the calibration count on the module in slot 3.
CAL:COUN? 3
Typical Response: +39391
