REs":
When the input 'AdjREsInp' is enabled, the error code 123.0
is displayed initially until the resistance has been calculated.
It can take up to 10 s before the value measured for REs is
displayed.
During normal operation, the value entered for REs via the
HMC is displayed.
Normal operation: Neither of the two inputs 'AdjMTRInp' and
'AdjREsInp' is enabled and injection is taking
place.
Note: Only one of the binary inputs may be enabled
at any one time, otherwise an error code is
generated for the measurements Rfs, MTR
and REs (see table below).
