4.4. Special settings
4.4.1. Configuration of the current output
The connection of external devices to the current output of the meter is to be carried
out as described in chapter 2.1 Electrical connections.
The parameters are then set in column 'F Current output' of the coordinate matrix as
follows:
1. In coordinate F-02 (current mode) select the operating mode of the current output:
0: Off (default)
1: 4-20mA - current is always calculated from the physical value
2: 4-20mA - below the minimum value output of 3.5 mA
3: 4-20mA - above the maximum value output of 21.8 mA.
4: 0-20mA
2. In coordinate F-03 (current source) select the value for output:
0: Fixed value (default)
1: Operating flow rate
2: Sensor frequency
3: Fixed value of 4mA for calibration
4: Fixed value of 20mA for calibration
5: Standard flow rate
6: Temperature
7: Pressure
3. In coordinate F-04 (physical minimum) enter the lower limit for the physical value
at which 0 or 4 mA should be output.
4. In coordinate F-05 (physical maximum) enter the upper limit for the physical value
eintragen, at which 20 mA should be output.
5. In F-06 (current specification) a fixed value can be entered for the current which is
output with the entry 0 in coordinate F-02.
6. In F-07 (damping) the inertia oft he output can be set with values from 0 (mini-
mum) to 0.99 (maximum).
