3.6 Adjustment aid for all input and output values
Definitions:
1. Select output range of unit (according to table on p 31) so that Out
Out are within the output range.

2. Calculate the following auxiliary quantities:
Factor F =
Offset OF =
3. Set all DIP switches to OFF.
4. Calculate input range IR, set output range and offset OF using DIP switches.
4a. If the calculated offset OF does not correspond with an offset which can be
set with the DIP switches, set the closest offset (see table on page 31) and
activate the zero potentiometer (switch 2-5 OFF), short-circuit input and
adjust output to value Out
4b. If the calculated input range IR does not correspond with a range
which can be set with the DIP switches set the largest range within
0.33 x IR ... 3.30 x IR (see table on page 30) and activate the span
potentiometer (switch 2-4 OFF), modulate input with value ≠ 0
(see table on page 30 for terminals) and adjust output to required value
(e.g. apply In
