B. At each command point, verify both the dial indicator value
(Standard) and its corresponding conditioner feedback value
(Conditioner) by comparing them with the corresponding values on
the Calibration Data sheet.
Automated Controllers:
A. Adjust the Manual Cmd slider for each tensile and compressive force
command point on the Linearization Data window.
B. At each command point, verify both the dial indicator value
(Standard) and its corresponding conditioner feedback value
(Conditioner) by comparing them with the corresponding values on
the Calibration Data sheet
If the data is valid: Stop this procedure.
If the data is not valid: Proceed to the next step.
7. Reset Linearization Data window to default values.
Standalone FlexTest SE Controllers: Select Setup > Force > Calibration
> Cal Type > Gain/Linearization > <<Reset>>
Automated Controllers: Click Reset on the Linearization Data window to
return to default values.
8. Exercise the force standard.
Standalone FlexTest SE Controllers: Enable the front panel Dial, then
adjust the Setpoint to cycle the load standard readout between zero and full
tension three times. This removes sensor hysteresis. Select Status >
Setpoint
Automated Controllers: Use the Manual Cmd slider on the Manual
Command window to cycle the load standard readout between zero and full
tension three times. This removes sensor hysteresis.
Example: When calibrating a ±10 kN range, exercise the actuator between 0
and -10 volts. To calibrate the same force sensor for a different range such as
±5 kN, exercise the load standard between 0 and -5 volts.
9. Apply a tensile force command that is 80% of the range’s full scale.
Standalone FlexTest SE Controllers:
A. Using the Dial, adjust the Setpoint for a tensile force command that is
80% of the full scale range.
