Example 2: Following values shall be adjusted for the output A2:
1. Gain adjusted to 20 (-times amplification)
2. X-Offset adjusted to 25 %
Fig. 6.2.14 Gain (An.19) = 20,00 and X-Offset (An.20) = 25 %,
1.
+10 V
-100%
2.
+10 V
-100%
-10 V
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
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
