CALibration:COUNt?
CALibration:COUNt?
Syntax
CALibration:COUNt?
Description
This command queries the instrument to determine the number of times it has been calibrated. 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 its initial value.
For a more detailed discussion of the calibration procedures, see the Keysight 34970A/34972A 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:
- Internal DMM
Remarks
- The calibration count increments up to a maximum of 65,535, after which it rolls over to 0. Because 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? command (the mainframe must be unsecured; see CALibration:SECure:STATe OFF command). You can read the calibration count regardless of whether the instrument is secured.
- The calibration count is also incremented by calibrations of the DAC channels on the 34907A multifunction module.
- 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 query returns the calibration count indicating how many calibrations have been performed.
Example
The following query returns the calibration count.
CAL:COUN?
Typical Response: +273
