Automated:
A. Adjust the Manual Cmd slider for a 0% command.
B. Record the force standard’s readout value and corresponding
conditioner feedback reading at 0% command.
C. Adjust the Manual Cmd slider for a -2% tensile force
command.
D. Record the force standard’s readout value and its
corresponding conditioner feedback reading in the -2% row
of your record sheet.
E. Repeat steps E-G for other tensile force commands (typically
at -4, -6, -8, -10, -20, -40, -70, and -100 percent of full scale).
7. Record conditioner feedback readings at predetermined
compressive force command points.
Stand-Alone:
A. Use the Dial to adjust the Setpoint for a +2% compressive
force command.
B. Record the force standard’s readout value in the +2% row of
your record sheet.
C. Enter the corresponding conditioner feedback reading.
D. Repeat steps A-C for other compressive 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 +2% compressive force
command.
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
