Adding a 4-20mA Sensor
To add a 4-20mA sensor, perform the following procedure. There are some additional parameters to configure with
this type of sensor, including Unit of Measure and Resolution. 4-20mA sensors can be used for monitoring a variety
of conditions because the measured value corresponds to a current level, which is configured to represent the
conditions being monitored. Follow the steps outlined below to program a 4-20mA sensor.

Example shown, set values as
appropriate for your system.
High and Low Scaled Value are identified on the sensor as the sensing 'range'. It is important to
know this range before selecting the resolution. Low Scaled Value is the lowermost value or the
value equivalent to 4mA. High Scaled Value is the uppermost value or the value equivalent to
20mA indicated on the sensor. See Table 11 on page 14 for available resolution values.
