Set the coarse value with the ZERO DIP switches, the fine adjustment can be
implemented with the Zero potentiometer on the front.
5.4 Set amplification
The amplification is set with GAIN (Fig. 5.2) and the Gain potentiometer
(Front). To achieve the highest possible measured value resolution, you should
use the maximum output voltage of the amplifier ("10 V).
