5 Performance Tests and Calibration

Calibration Count

The meter provides the calibration count information for users to access
through front panel operation. Note that the meter was calibrated prior to
shipping out to users. Users are recommended to record the initial value
of the calibration count once receiving the meter.
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 be reset to 0. The calibration count can be read from the front panel
after the meter has been unsecured, see the following steps:
1 In adjustment mode, press and hold
2 Take note of the calibration count to keep track of the number of
3 Press and hold
