Value with negative sign means flow simulation opposite to the main flow direction.
The respective relay is activated simultaneous to the chosen flow rate (see chart).

In this case „signal = 100%“ means the simulation of a flow rate of 100% of the set full
scale. By pressing the key

5.1.3
Calibrating the analog output
The power output can be calibrated with this menu point.
Notice:
A calibration of the analog output is already done in the factory. A
recalibration is normally not necessary.

.
Offset (4 mA) and range (20 mA) can be set in the calibration menu. By pressing the
keys
↑
(increase) and
→
(reduce) the value can be calibrated at the analog output
with the help of a current meter. The values are acknowledged with the key E. The
calibration is also effective for the range 0-20 mA.
1. Connect a current meter at the analog output.
2. Setting of the offset (4 mA) with the

3. Setting of the range (20 mA) with the

5.1.4 Calibrating the medium control
Notice:
In order to compensate different conductivity of the media, cable
length or sizes at the medium control, a calibration is
recommended. This is important, if the medium control will be
activated.
