Example 3:
The example also shows the popular method. The whole scale of the potentiometer can be
used as desired. In addition to signals of 0 to 10V and 4 to 20mA, the popular voltage signals
also include signals of 0 to 5V, 20 to 4mA or that under 10V. Regarding the setting, please
refer to the following examples.

Example 4:
This example shows a potentiometer range of 0 to 5 Volts. In addition to adjust gain, you also
can set Pr. 01-00 to 120Hz.

Example 5:
In this example a 1-volt negative bias is used. In a noisy environment, it is advantageous to
use negative bias to provide a noise margin (1V in this example).
