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 and4 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.
Example 5:
In this example a 1 volt negative bias is used. In a noise environment, it is advantageous to use
negative bias to provide a noise margin (1V in this example).
