As part of installation checks, the operator can validate and calibrate the system. Once the installation is
done, the operator must validate the system. By choosing the Validation option under Maintenance Routines,
the operator can perform Sine Wave Validation.
Click Go on the Sine Wave Validation screen. The chair should rotate back and forth slowly. Watch the sine
wave. There should be two colored sine waves that are superimposed into one curve. If the curves match,
there is no need to calibrate.

If the curves do not match, then switch to the Calibration Maintenance Routines. Click Go under Drift
Calibration. The chair should be stopped and not drifting. If the chair is moving slowly, remove the drift using
the Drift Offset left / right arrow buttons. Once the chair stops moving, click Stop. Then click Go under
Velocity Tach Calibration. The chair will spin clockwise. Two lines will appear and eventually be
superimposed. The calibration will stop automatically.
