Linearization parameters
If the linearization mode "Special Curve" is selected, the "Linearization" leaf must be opened:
■
Up to 32 value pairs can be entered
■
X values must be entered in increasing order, Y values must rise or fall monotonically (red
= error)
■
Range end values must correspond to those in the 4-20 mA leaf
■

Linearization
Upper Limit of
Proportional
Range
Upper limit value of proportional range. The adapter outputs a
warning if the current input exceeds this level.
20.5 mA
Lower Limit of
Proportional
Range
Lower limit value of proportional range. The adapter outputs a
warning if the current input drops below this level.
3.8 mA
Lower Fault-
Current Value
Min. current output by 4 ... 20 mA device when in fault
condition.
The adapter outputs an alarm if the current input reaches or
drops below this level.
3.6 mA
Trim Loop Current
Zero
When pressed, calibrates the 4 mA signal of the connected
device. 4 mA must be simulated or an "empty" calibration
made.
–
Trim Loop Current
Gain
When pressed, calibrates the 20 mA signal of the connected
device. 20 mA must be simulated or a "full" calibration made.
