Description
CURR. TRIM 4mA (045)
Entry
Enter the current value for the lower point (4 mA) of the current linear regression line.
You can adapt the current output to the transmission conditions with this parameter and
"CURR. TRIM 20mA".
Perform the current trim for the lower point as follows:
1.
Select the SIMULATION MODE group.
(Menu path: (GROUP SELECTION)

2.
Select the "Current" option via the SIMULATION MODE parameter.
3.
Enter "4 mA" for the SIM. CURRENT parameter.
4.
Select the SYSTEM 2 group.

parameter.
Input range:
Measured current ±0.2 mA
Factory setting:
4 mA
CURR. TRIM 20mA (042)
Entry
Enter the current value for the upper point (20 mA) of the current linear regression line.
You can adapt the current output to the transmission conditions with this parameter and
