3. Press the button.
4. Select the desired unit with the or button.
The pressure measurement is converted to the new pressure unit.
5. Use the button to confirm.
6. Navigate to the "Pressure reference" parameter [33].
7. Press the button.
8. Select the specific pressure unit for your application (absolute pressure, gauge pressure,
none) with the or button.
Result
● The selected pressure unit and pressure reference are displayed as alternating values in the
measurement view.
● If the converted pressure measurement has more than 5 digits, "#####" appears in the
measurement view: Adjust the unit so that a lower value is displayed, e.g. bar instead of
mbar.
