Putting into Operation

5 Putting into Operation
If the manufacturer's settings, such as the coarse measuring range, are
retained the operation is limited to the following points:
5.1

Select Measuring Range

With the factory settings measuring range 1 (±1 mV/V) is always switched on.
Measuring range 2 (calibration at ±0.2 mV/V) can be selected either internally
via DIP switch 24/4 or externally by connecting a single‐pole changeover
switch to pin 25c (see chapter 6.2).
5.2

Bridge Zero Balancing

The bridge zero balancing is carried out by means of the screwdriver poten­
tiometers P23 (fine) and switches S22 (coarse) and S23 (polarity) (see also
chapter 6.4).
5.3

MR Fine Adjustment

The fine adjustment of the measuring range is made seperately for both ranges
by means of the screwdriver potentiometers P21 (measuring range 1) and P22
(measuring range 2). The potentiometers, which are accessible from the front,
permit corrections of approx. 35 % (related to the set measuring range). As far
as measuring range 1 is concerned, the fine adjustment is also possible via an
external potentiometer (see chapter 6.3).
Notice
P22 must not be altered in order not to detune the manufacturer's setting
(MR2 ±0.2mV/V) (see chapter 6.5).
