Using a load standard • Adjust Manual Cmd slider for 0 kN. Then zero the load
standard readout.
Using dead weights • Remove all dead weights. On the Inputs panel, click on
the Offset/Zero tab, and then adjust Manual Offset for
a signal value of 0 kN on the DVM or Station Signals
panel.
D. Adjust the Manual Cmd slider to achieve a load standard
reading of 20% compression and record the meter reading.
Repeat this step for 40%, 60%, 80%, and 100% compression.
2. Record the data points for the tension.
Stand-Alone:
A. Adjust the Setpoint to achieve a load standard readout of
zero.
B. Adjust the Setpoint between zero and full tension three
times. This exercises the force sensor to remove hysteresis.
C. Establish the zero reference.
