OFF
Autozero
If the actual value is not “0 Pa Δp” in pressureless state a
zero-point adjustment is possible with fuction “Autozero”.
This may be necessary, for example, in case of heavy ther-
mal fluctuations in the sensor environment or non-vertical
mounting.
Proceed as follows:
1. Pull off the pressurised hoses.
2. Switch function “Autozero” to “ON”.
3. The display switches to the actual value display and the
value “0” is displayed after zero point calibration has
taken place.
4. The necessary difference up to “0” is displayed in the
BASE SETUP under “Offset”.

Offset
Alternatively to the automatic zero point calibration, the offset
value can also be set manually.
