13. Record conditioner feedback readings at predetermined compressive force
command points.
Standalone FlexTest SE Controllers:
A. Use the Dial to adjust the Setpoint for a +2% compressive force
command.
B. Record the force standard’s readout value 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).
Automated Controllers:
A. Adjust the Manual Cmd slider for a +2% compressive force
command.
B. Record the force standard readout signal and corresponding
conditioner feedback reading at the +2% command line 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).
14. Turn off system hydraulics.
15. 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.
16. Turn on system hydraulics.
17. 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.
B. At each command point, verify both the force standard value
(Standard) and its corresponding conditioner feedback value
(Conditioner).
C. Check validity before entering each pair of values on a new Calibration
Data Sheet.
