Calibration count
You can query the instrument 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 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 count increments up to a maximum of 65,535 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 DAC
channels on the multifunction module.
