Calibration count
The instrument counts the number of times it has saved calibration data. Your instrument was calibrated at the
factory; when you receive your instrument, read and record the initial count. You can only read the calibration count
by sending the CAL:COUNt? query, and the calibration count is not change by a power cycle or *RST.
If Auto Save is enabled, the count increments whenever a calibration point is calibrated successfully. To avoid double
counting, do not manually save the count with Auto Save enabled.
