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 4 mA
Curr. trim 20mA (136)
Navigation Expert → Output → Current output → Curr. trim 20mA (136)
Write permission Service engineers/Expert
Description Enter the pressure value for the upper point (20 mA) of the current partial regression
lines. Using this parameter and "Curr. Trim 4 mA", you can adapt the current output to the
transmission conditions.
Options Carry out the current trim for the upper point as follows:
• In the "Simulation Mode" parameter, select the "Current" option.
• In the "Sim current" parameter, configure the value "20 mA".
• Enter the current value measured using the switching unit in the "Curr. trim 20mA"
parameter.
Input range Measured current ±1 mA
Factory setting 20 mA
Offset trim 4mA (137)
Navigation Expert → Output → Current output → Offset trim 4mA (137)
Write permission Service engineers/Expert
Description Display/enter the difference between 4 mA and the value entered for the parameter "Curr.
trim 4mA".
Factory setting 0
