1. For zero point setting, the device must be in operation for
at least 60 minutes.
2. Connect pressure inputs P (+) and P (–) with a hose.
(Pressure difference between the inputs = 0 Pa).
3. For zero point setting, press pushbutton uninterrupted for 10 seconds.
By pressing the pushbutton, a countdown of ca. 10 seconds is started.
The yellow LED is blinking and the countdown is shown on the display
(optional).
Zero point calibration takes place after the countdown period.
This is indicated by continuous LED light and at the display (optional) by
switching from "AUTO 0" to "PROG 0".
Note: By releasing the pushbutton during the countdown
(counter > 0), zero point setting is immediately cancelled!
Automatic offset setting:
Display readout:
Manual offset adjustment:
Automatic zero point calibration (optional):
The offset potentiometer functions additionally and
independently for automatically setting the zero point.
With the OFFSET potentiometer, a deviation outside of the zero
point can be aligned.
The range for adjustment is ca. ± 10 % of the pressure range.
A
zero point calibration
is carried out cyclically via an internal
valve.
The cycle time can be set between 15 minutes and 24 hours
using the „SET“ potentiometer.
During the automatic calibration, the output value remains at
its last pressure value.
