As the potentiometer does not possess a scale, one can deploy analog output 6 (X8.1 / X8.2)
as help for the setting (connect the voltmeter, range 0 – 10V). If the potentiometer is
changed, (no PC mode) the analog output is automatically switched over to the output of the
potentiometer value.
The setting range of R309 is relatively large, and extends from 1 – 1500 network periods. For
this reason, the setting help is divided into two intervals:
Interval 1: 0 - 100 periods
0 - 5V, meaning 5V = 100 periods, 2.5V = 50 periods, 1 period = 0.05V
Interval 2: 101 - 1500 periods
5 - 10V, meaning 5V = 100 periods, 10V = 1500 periods, 1 period =
0.00357V (+5V)
The following figure and the table display the respective values:
