6.3 Gain setting
6.3.1 Coarse adjustment
The gain is adjusted coarsely on three amplification stages (stages 1 - 3). DIP switches are
assigned to each amplification stage. Multiplying the gain factors set on each stage results in
the total coarse gain V

(also refer to Chapter 4.1.3.1 titled Mounting rail version Page 13).
Stage 1:
The gain can be set with DIP switches S1 S2.

10
100
Only factors of 1, 10 and 100 are available here. It is not possible to combine these factors,
forexample, to obtain 110.
Stage 2:
The gain can be set with DIP switchesS3 S10.

32
The gain factor here can be adjusted with a resolution of 0.25. The switches can be set in any
required combination to obtain, for example, a gain of 33.25.
Stage 3:
The gain here can be set with DIP switches S13 S14.

8
Only factors of 2, 4, 6 and 8 are available here. Combinations are not possible.
The specified gain factors always refer to the 10-V output. The 5-V output and current output
are derived from the 10-V output and are available simultaneously. During subsequent fine
adjustment, only the output requiring the highest degree of precision is observed. The maximum
deviation at the remaining outputs is then 0.2%.
The switch settings are described in detail in Chapter 4.1.3 titled Meaning of the DIP switches
