Agilent Technologies Switch/Measure manual Calibration Count

2Features and Functions

Calibration Count

You can query 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.

•The calibration count is stored in non- volatile memory in the mainframe, and does not change when power has been off, after a Factory Reset (*RST command), or after an Instrument Preset (SYSTem:PRESet command).

•The calibration counts increments 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 calibration count is also incremented with calibrations of DAC channels on the 34951A Isolated DAC Module and 34952A Multifunction Module.
