Reference box.
D. Set Shunt State (+) to Off.
Automated Controllers:

Task 9 Save the calibration
It is important that you save your sensor calibration values.
Standalone FlexTest SE Controllers: Select Setup > Open/Save Parameters >
<<Save>>
Automated Controllers: On the Station Setup window Inputs panel, click the
Calibration tab, and then Save. This saves current calibration values on the
Calibration, Sensor, and Shunt tabs to the sensor calibration file.
Note Systems equipped with full range conditioners (e.g., Model 493.25
DUCs) do not require or support multiple ranges. They use one range
that is typically set to 100%.
