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.
Stand-Alone:
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:
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).
