accidental or unauthorized calibrations of the multimeter. When you first receive your
multimeter, it is secured. You must unsecure it by entering the correct security code
before you can calibrate the multimeter (see

CALibration:COUNt? queries the multimeter to determine the number of times a
point calibration has occurred. A complete calibration of the multimeter increases
the count by the number of points calibrated. It is not a record of complete
calibrations. The count is stored in non-volatile memory.
