Set the coarse value with the
ZERO
DIP switches, the fine adjustment can be
implemented with the
Zero
potentiometer on the front.

Set amplification
The amplification is set with
GAIN
Gain
potentiometer
(Front). To achieve the highest possible measured value resolution, you should
use the maximum output voltage of the amplifier (
10V).
