Because of the high adjustment of the gain the change of the output voltage from -
10V to +10V takes place within a very small alteration range of the variable to be
indicated. Thus the output can be used as „switch“ (HI- and Low-level) for some
applications. The adjustment of the X-Offset determines the „switching level“.
This means:
0...20 %
of the variable to be indicated correspond to
-10 V at A2
20...30 %
of the variable to be indicated correspond to -10...+10 V at A2
30...100 %
of the variable to be indicated correspond to
+10 V at A2
Fig. 6.2.14
Gain (An.19) = 20,00 and X-Offset (An.20) = 25 %,
Example 2:
Following values shall be adjusted for the output A2:
1. Gain adjusted to 20 (-times amplification)
2. X-Offset adjusted to 25 %
