Calibration Procedures 128
5. Select the control mode to which shunt calibration applies.
Standalone FlexTest SE Controllers:
Select Setup > force or strain> Calibration.
Automated Controllers:
A. In the Station Manager window’s Display menu, select Station
Setup.
B. In the Station Setup window’s navigation pane Channels, locate and
select the control mode needing a shunt calibration (e.g., force or
strain).
C. In the Station Setup window, click .
6. Apply the shunt calibration.
Standalone FlexTest SE Controllers:
A. Locate the shunt calibration controls toward the bottom of the
calibration menu.
B. Apply the shunt by setting the Shunt State (+) control to On.
Automated Controllers:
A. In the Inputs panel, click the Shunt tab.

7. Compare the Current Shunt Value to the Shunt Reference Value.
Consider recalibrating the sensor/conditioner pair if the values differ by
more than 0.2%. For example, if the Shunt Reference Value is displayed in
Volts, consider recalibrating if the Current Shunt Value differs more than
20 mV.
