3.5 FOCAL SPOTS CONFIGURATION
This configuration determines which mA station will be the smallest mA station
for the Large Focal Spot. It is possible to configure all the mA stations for the
Small Focal Spot or for the Large Focal Spot.
The smallest mA station for the Large Focal Spot must be selected according
to the Tube ratings for the Small Filament and the customer preference.
IF THE mA STATION FOR FOCAL SPOT CHANGE IS NOT
CONFIGURED ACCORDING TO THE X-RAY TUBE RATINGS,
THE TUBE FILAMENTS MAY BE PERMANENTLY DAMAGED.
1. With the generator OFF, set dip switch 3024SW2-3 on the ATP Console
CPU Board in “On” position to permit the service mode.
2. Power ON the System. Enter in calibration mode by pressing the “Manual
Calibration” button on the GSM program. Select any workstation (WS)
of the corresponding X-ray Tube and press the “OK” button.
3. Select the smallest mA station for the Large Focal Spot using the
“Increase”or“Decrease” mA buttons. When is required to configure all
mA stations for the Small Focal Spot, select “E01” Memory Location.
Default value is factory set at 200 mA except when using X-ray
Tubes with Small Focal Spot smaller than 0.6 .
4. Press the “Toggle” button to store the select mA station and then press
the “Confirm”or“Dismiss” buttons to confirm or cancel the process.
When it is confirmed, the ATP Console CPU Board emits a
“double-beep”.
IF THE FOCAL SPOT SWITCH-OVER POINT IS CHANGED
AFTER mA CALIBRATION, THE mA STATIONS AFFECTED
MUST BE RE-CALIBRATED.
5. Exit from calibration mode.
