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.
