Description of device parameters
Deltabar FMD71, FMD72
48
Description
Enter the pressure value for the lower point (4 mA) of the current partial regression lines.
Using this parameter and "Curr. Trim 20 mA", you can adapt the current output to the
transmission conditions.
Options
Carry out the current trim for the lower point as follows.
• In the "Simulation Mode" parameter, select the "Current" option.
• In the "Sim current" parameter, configure the "4 mA value".
• Enter the current value measured using the switching unit in the "Curr. trim 4mA"
parameter.
Input range
Measured current ±0.2 mA
Factory setting
