Note
Negative value for 2-wire connection
A negative value is possible in these constellations:
•
Configured conductor compensation > sum of conductor resistance and resistance
•
Short-circuit on the input and configured conductor compensation
With a negative value the value 7FFF
H
is generated. The diagnostic message "Violation of high
limit" is signaled for the channel in question.
