Note:
The compression arm angle must be calibrated to allow automatic selection of view names.
Note:
The sign convention for Senographe applications is illustrated here, shown
looking at the tube head or chest wall of the Senographe.
6-1 Principle
• Arm rotation travel limits are factory set; However, if parts have been replaced or disturbed which
affect the software or hardware limits, calibration must be carried out.
• Calibration is necessary to set travel limits in software, defining the maximum positive and negative
usable angles.
- The procedure first calibrates the 0° position to establish a reference point for the measurement
system (potentiometer and encoder).
- Travel limits are then set at the 185° and -165° positions
• Optical sensors ("optical forks") are used to recognize and stop any movement beyond the software
limits, before impact with mechanical stops.
6-2 Calibration procedure
• Move the lift to a height which will allow rotation of the arm between 185° and -165°.
• Select the Rotation Calibration on the ADS LCD screen: Service Desktop/Calibration/Positioner/
Rotation.
• You are asked to follow the instructions displayed on the Gantry readout:
0°
180°
