Calibration Count
The multimeter provides the calibration count information for you to access
through front panel operation. Note that the multimeter was calibrated prior to
shipping out to users.
The count value increases by one for each calibration point, from 0000 up to the
maximum of 19999. After the maximum count, the calibration count will reset to
0. The calibration count can be read from the front panel after the multimeter has
been unsecured:
1 In adjustment mode, press and hold for more than one second to view
the calibration count viewing mode. The primary display indicates the
calibration count value while the secondary display indicates “ Cnt ”.
2 Take note of the calibration count to keep track of the number of calibration
counts that has been performed.
3 Press and hold for more than one second to exit the calibration count
mode.
NOTE
You are recommended to record the initial value of the calibration count once
receiving the multimeter.
