OTHER ADJUSTMENTS AND CALIBRATIONS
2.2 Calibrating the elbow arm and C-arm gear ratios
Elbow arm gear ratio
NOTE
Technical Manual
The tape material of the traction belt located on the elbow arm has been changed. The X-ray
units with serial number RPX 235922 or greater, manufactured after March 2006, are
equipped with the new traction belts. Because the traction belt with new tape is slightly thicker
than the old one, the correct gear ratio can be selected. The correct ratio has been set at the
factory, but it has to be checked and changed if necessary, when replacing the traction belt.
From the list on the i600 display select Positioning calibration (i640).
Figure 100
From the list on the i640 display that appears select Elbow arm ratio calibration (i64.2).
Change the ratio value by touching the Default field. The Default 1 (336.578) is for old trac-
tion belt and the Default 2 (335.646) is for new traction belt.
Figure 101
The X-ray unit must be switched off and on after changing the ratio value. After switch-
ing the X-ray unit on again, the angle sensors mut be calibrated.
