The alignment operation runs also in operating mode. In this case,
settings for bFdn (line 13) and bFuP (line 14) in programming field 2
must be „0" .
b) Two-point alignment by Teach-In
The two-point alignment by Teach-In enables flexible calibration of
the indicated value to the 10 V respectively 20 mA analog signal.
The reference points 1 and 2 can optionally be set anywhere within
the visualized positive measuring range. See fig. 1 and 2.
Prior to the alignment, enter the following settings in programming
field 3: line 41 = 0; in line 26 the offset.
