Page: 53 / 58

Press the Back button to return to the ‘Test QIC’ menu
This test can be executed, independent from the current settings of the instrument.
- Press setup button
- Go to Calibration
- Select Air Calibration
- Select Adjust now
- Press Back button
- Go to Commissioning
- Go to Advanced setup
- Go to Test QIC
- Set Key to ‘Factory Mode’
- Set SC Input to the range in which you want to test the accuracy (see table below)
Set BOX 2 to the values listed below to simulate the resistivity (
Ω
) input.
Note: In the QIC form a table is shown containig 27 fields.
For a proper accuracy test however a subset of five fields is recommended.
