•

Select the I.I. full field of view and open the collimator to the size of the measurement
chamber.

•

Confirm the message

"

with OK.

•

Click Fluoroscopy on.

•

Change the mA value so that the dose rate desired appears on the dosimeter.

Dose rate values to be set:

Note the factor for the chamber. If you are using the Dali -/ Nomex chamber for the mea-
surement, the dose rate value must be increased by 6%.

•

Exit the dose rate adjustment field with OK after the dose rate has been reached.

•

Enter "300 mV" in the B-Signal Value field.

•

Click OK.

•

Wait for the data to be transferred to the generator (may take some time).

•

Click "Fluoroscopy on" in the CCD Brightness Adjust field if the value 0 + 1 is not
reached: Record the nominal-actual values with the algebraic sign. Exit the XCS soft-
ware.

•

In case of deviations:

- Connect the service-PC to the Multiline.
- Call up "Parameter" in the Adjustment menu.
- Click "Get from Unit."
- Select Parameter: "am 7 TV-Iris" in the parameter groups.
- Select Parameter "FLUORO Zoom 0".
- Reduce or increase the TV iris value (nominal/actual) in the Value Actual field.

If the TV iris value is negative (nominal/actual), it should be reduced.
For example, a value of "- 5" means that the nominal/actual value recorded earlier must
be reduced by a factor of - 5 x 10, i.e. by - 50.

- Click Set Value after the change.

The changed value is marked in the parameter window
(i.e. the value is not yet transferred to the unit).

- Click Put to Unit.

The message "Component... to continue" is displayed.

- Click OK after the automatic Reset.
- Switch off the system for a complete reset.
- Switch on the system.
- Record the dose rate again.
