the FOV button.
5. Measure the height of the flat surface of the detector (A) with respect to the top of the gantry base
plate (B), as shown.
6. Use the control buttons on the Tube Head to move the lift down until the measured height at the
detector is 670 ±2 mm (26.4 ±0.1 inches).
Note:
If you move the detector below 670 ±2 mm and too close to 660 mm, the lower optical fork is ob-
structed, invoking a system halt. If you invoke a halt you have to move manually the lift shaft to
raise the detector and start again.
7. When the measured height at the detector is 670 ±2 mm (26.4 ±0.1 inches), press the FOV size but-
ton (behind the Tube Head). This action signals the completion of the lower limit adjustment.
The voltage of the Lift Potentiometer is sent to the firmware of the Lift Board and stored as the Lift
Potentiometer Lower Reference Voltage.
The Gantry LCD updates with the following message:
Lower position successfully calibrated. Move to upper position. When reached press FOV button.

6-2-3 Upper Limit Adjustment (Lift Potentiometer Upper Reference Voltage at 650 mm)
Use the following steps to calibrate the upper limit of the Lift Potentiometer:
1. When the Gantry LCD instructs you to move the lift to the upper position, use the control buttons on
the Tube Head to move the lift up to its highest possible position until it automatically stops.
The movement stops automatically when the lift reaches 650 mm above the lower limit. The 650 mm
is determined by the Lift Encoder which accurately translates lift screw turns to height traveled.
2. Once the lift reaches its highest position and automatically stops, press the FOV size button (behind
the Tube Head). This actions signals completion of the upper limit adjustment.
The voltage of the Lift Potentiometer is sent to the firmware of the Lift Board and stored as the Lift
