Feedback Value [mA] Actual measured output current (2 – 22 mA).
Lower Range [mA] Set the lower range value of the current output
(default 3.8 mA).
Upper Range [mA] Set the upper range value of the current output
(default 20.5 mA).
Output Value [mA] Calculated current to output (0/4 – 20 mA).
Error Mode Error Current selection.
0 = HIGH (22 mA)
1 = LOW (2 mA)
Error Value [mA] Current outputted if error events is detected (2 ; 22
mA).
U – I Selection 0 – 10 V (activate voltage output)
0 – 24 mA (activate current output)
Field Calibration
Calibration Test Mode Activates/deactivates test mode of current loop. If
activated, the “Test Current” is output. (Reboot
deactivates test mode automatically).
Calibration Test Value
[mA] Set the output current in test mode (2 – 23.9 mA)
Trim Offset (Calibra-
tion) Current Loop calibration.
Trim Gain
(Calibration)
Current Loop calibration.
Upper Cal. Point Value measured with external amperemeter and
usually used for gain calibration of current loop.
Lower Cal. Point Value measured with external amperemeter and
usually used for offset calibration of current loop.
NOTICE
To calibrate the current output follow the calibration instructions in chapter 6.4.8.
