6.4.6 Current Configuration
Scroll to “ CURRENT CONFIG ” from “ OUTPUT CONFIG ” using the ▲▼ keys and press ENTER.
Use the ◄► keys to select either UNIDIRECTIONAL or BIDIRECTIONAL

For a Bi-Directional configuration the, negative full scale output from the sensor is mapped to the
lowest value of current. A zero load output from the sensor is mapped to the middle value and
the positive full scale output from the sensor is mapped to the highest value of current. For
example if 4-20 mA is selected, the sensor’s negative full scale output is mapped to 4 mA, the
zero load output from the sensor is mapped to 12 mA, and the sensor positive full scale output is
mapped to 20 mA.
This configuration is recommended for bidirectional sensors.

For a Unidirectional configuration, the zero load output from the sensor is mapped to the lowest
value of current and the sensor’s positive full scale output is mapped to the highest value of
current. For example if 4-20 mA is selected, the zero load output from the sensor is mapped to 4
mA, and sensor’s positive full scale output is mapped to 20 mA. For negative values of load,
output current decreases until reach 0 mA.

This configuration is recommended for unidirectional sensors in order to obtain more resolution.
A prompt will be shown to set this value as a default setting.
