and the software will calculate the Pre-Amp and Post-Amp gain
values automatically.
When you are calibrating an DC conditioner, use the Post-Amp gain
control to increase gain. If more gain is needed, you must disable
hydraulics and increase the Pre-Amp gain. You can then turn on
hydraulics and continue to adjust the Post-Amp gain.
1. Select Gain/Delta-K for Cal Type.
Stand-alone— Path: Setup > Force > Calibration > Cal Type >
Gain/Delta-K
Automated— Select Gain/Delta-K for Cal Type on the
Calibration tab of the Inputs panel.
2. Exercise the force standard.
Stand-Alone— After enabling the front panel Dial, adjust the
Setpoint to cycle the load standard readout between zero and full
tension three times. This removes sensor hysteresis. Path: Status >
Setpoint
Automated— Use the Manual Cmd slider on the Manual
Command window to cycle the load standard readout between
zero and full tension three times. This removes sensor hysteresis.
Example: When calibrating a ±10 kN range, exercise the actuator
between 0 and -10 volts.
3. Apply a tensile force command that is 80% of the full scale range.
Stand-Alone:
A. Using the Dial, adjust the Setpoint for a tensile force
command that is 80% of the full scale range.
B. Verify that your force transducer feedback signal is 80% of the
full scale range.
Automated:
A. Open the Manual Command window, and then click on the
Enable Manual Command.
B. Adjust the Manual Cmd slider on the Manual Command
window for 80% of the full scale range.
C. Use the Station Signals panel to verify that your force
transducer signal equals 80% of the full scale range.
