Output(s) value on analyzer
failure
Choose the desired signal level to cause
a failure condition. The choices are:
Actual
BeginOfRange
EndOfRange
BeginOfRange-10%
BeginOfRange+10%
Output number
Choose the output number (1-8) for set-
ting the fine adjustment.
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 → key. Adjust
to the desired value with the ↑ or ↓ key
and confirm with the ↵ key. 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 sig-
nal chosen in the “Choose signal”
