B. Record the standard’s readout signal and corresponding conditioner
feedback reading in the +2% row of your record sheet.
C. Repeat steps A and B for other compressive force commands (typically
at +4, +6, +8, +10, +20, +40, +70, and +100 percent of full scale).
8. Turn off system hydraulics
9. On the Linearization Data window, enter the force standard values and
corresponding conditioner feedback readings for all command points
previously recorded on a separate sheet.
Standalone FlexTest SE Controllers: Select Setup > Force > Calibration
> Cal Type > Gain/Linearization > Linearization Data
Automated Controllers: Click Linearization Data on the Calibration tab
to open the Linearization Data window.
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.
Standalone FlexTest SE Controllers: Select Setup > Force > Calibration
> Cal Type > Gain/Linearization > Linearization Data
Automated Controllers: 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.
Standalone FlexTest SE Controllers:
A. Using the Dial, adjust the Setpoint for each tensile and compressive
force command point on the Linearization Data window.
