5.7 Zero point setting
5.7.1 Standard
Connect the voltage supply one hour before the zero point setting!
1. Remove both hoses from the pressure connections ⊕ and ⊖.
2. Press the zero button until the red LED switches on.
3. Wait until the LED switches o again and install the hoses to the
pressure connections again.
4. In normal operation, we recommend that a zero point calibration is
carried out every 12 months.
5.7.2 Automatic zero point setting (option)
The automatic zero point setting makes the instrument maintenance-
free. The element corrects the zero point from time to time and thus
prevents a zero-point drift in the piezoresistive sensor element.
During the zero point setting the display and output value remains at the
last measured value. The automatic zero point setting takes 3 seconds
and is repeated every 10 minutes.
