Indication on the display after calibration has been completed.
Correction values are stored.
Push rocker switch to the left!
Step 5:
Indication:
- Voltage is calibrated.
- Date of calibration.
- Calibration valid for medium-voltage range.
Verification if calibration has been successfully completed:
Applied calibration voltage shall be identical with the voltage va-
lue indicated on the display (to be found in the menu under mea-
surement results).
