B. Verify that your force transducer feedback signal is 80% of the full
scale range.
Automated Controllers:
A. Adjust the Manual Command slider for a compressive force
command that is 80% of the full scale range.
B. Use the Station Signals panel to verify that the compressive force
signal is approximately equal to 80% of the full scale range.
12. Record conditioner feedback readings at predetermined tensile force
command points.
Note After shutting down system hydraulics, you will enter these recorded
readings on the Linearization Data window.
Standalone FlexTest SE Controllers:
A. Use the Dial to adjust the Setpoint for a 0% command.
B. Record the force standard’s readout value and corresponding
conditioner feedback reading in the 0% row of your record sheet.
C. Use the Dial to adjust the Setpoint for a -2% tensile force command.
D. Record the force standard’s readout signal and corresponding
conditioner feedback reading in the -2% row of your record sheet.
E. Repeat steps C and D for other tensile 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 0% command.
B. Record the force standard readout signal and corresponding
conditioner feedback reading at the 0% command line of your record
sheet.
C. Adjust the Manual Cmd slider for a -2% tensile force command.
D. Record the force standard readout signal and corresponding
conditioner feedback reading at the -2% command line of your record
sheet.
E. Repeat steps C and D for other tensile force commands (typically at -4,
-6, -8, -10, -20, -40, -70, and -100 percent of full scale).
