B. Enter the tension sensitivity value (+mV/V) in the Pos Tension entry
box.
C. Enter the compression sensitivity value (-mV/V) in the Neg
Compression entry box.
D. Enter the calibration excitation value (Vdc) in the Excitation entry
box.
Automated Controllers:
A. On the Inputs panel, enter the full scale force values in the Fullscale
Min/Max entry boxes.
B. Adjust Pos Tension for the required tension sensitivity value (+mV/V).
C. Adjust Neg Compression for the required compression sensitivity
value (-mV/V).
D. Adjust Excitation for the required calibration excitation value (Vdc).
mV/V Positive
Compression Calibration
Use the following procedure if your force transducer is set up so that a positive
output represents actuator extension (compression).
1. Select mV/V Pos Comp for your calibration type.
Standalone FlexTest SE Controllers: Select Setup > Force > Calibration
> Cal Type > mV/V Pos Comp
Automated Controllers: Select mV/V Pos Compression for Cal Type on
the Calibration tab of the Inputs panel
2. From the Calibration Data sheet for your force transducer enter the
following values on the Calibration submenu or tab:
Standalone FlexTest SE Controllers:
A. Enter the full scale force values in the Minimum and Maximum entry
boxes.
B. Enter the tension sensitivity value (-mV/V) in the Neg Tension entry
box.
C. Enter the compression sensitivity value (+mV/V) in the Pos
Compression entry box.
D. Enter the calibration excitation value (Vdc) in the Excitation entry
box.
