Model 493.02 Controller Service
Calibration
155
Automated:
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.
Stand-Alone— Path: Setup > Force > Calibration > Cal Type >
mv/v Pos Comp
Automated— 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:
Stand-Alone:
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.
