5. Mount the force standard.
6. If you using the Gain/Delta K or Gain/Linearization for calibration,
set the following initial conditioner calibration values on the
Calibration submenu.
Force Transducer
Load Standard
The illustration shows a load
standard in-line with the force
train coupled with the force
sensor.
The load standard reacts like a
stiff specimen. Be sure the
gain settings (PID) for the
control mode are appropriate.
If the control mode has not
been tuned yet, use some
default values. Then recalibrate
the sensor after the initial
tuning.
