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).
