Force transducer
recalibration
If the force transducer has been previously calibrated, use the
following procedure:
1. Locate the calibration data sheet for the appropriate conditioner.
2. Turn off system hydraulics.
3. Click Linearization Data to open the Linearization Data window.
Stand-Alone— Path: Setup > Force > Calibration > Cal Type >
Gain/Linearization > Linearization Data
Automated— Click Linearization Data on the Calibration tab
of the Inputs panel.
4. Transfer Standard and Conditioner data from the conditioner’s
calibration data sheet to corresponding data entries on the
Linearization Data window.
5. Turn on system hydraulics.
6. Verify linearization data.
Stand-Alone:
A. Using the Dial, adjust the Setpoint 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.
Automated:
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.
