The signal range of the analog output
should not be less than the smallest
range of the channel. Otherwise the
analog output may exhibit excessive
noise.
Output current:
Select the desired output range in the
"Output current range:" line. The options
are 0...20 mA or 4...20 mA.
Hold output during calibration:
Enable this option to hold the analog out-
put to the last value during calibration.
Pressing the F5 (More...) softkey
changes to the submenus "Output Signal
if Assigned Module Fails" and "Fine Ad-
justment."

Operation mode:
Normal : The absolute measurement sig-
nal will be sent to the analog output.
Adjust 0V: Used to set the display equal
to the analog output for 0V and 0 mA. Life
zero signals (4-20 mA and 2-10V) are set
automatically and cannot be adjusted.
Adjust 10V: Used to set the display equal
to the analog output for 10V and 20 mA.
Select the "Fine adjustment for 0% out-
put" and/or "Fine adjustment for 100%
output" lines with the ↵ or → softkey. Ad-
just to the desired value with the ↑ or ↓
softkey and confirm with the ↵ softkey.
The range of values are:
3000 to 6000 for 0% (default 4096)
600 to 1000 for 100% (default 819)
The last three lines of the "Analog Output
Setup" menu are display only for configu-
ration values of the analog output.
Signal name: The name of the signal
chosen in the "Choose signal" menu.
Current signal value: The current value
of the variable.
Source module: The name of the module
chosen in the "Choose signal source
module" menu.
Pressing the F5 (More...) softkey
changes to the submenu "Special Scaling
for Concentration Signal."
-- Special Scaling for Concentration Signal –
(Scaling is the same as range limits)
