OK and CANCEL

When you complete your editing of ion chamber parameters, you may use OK or CANCEL to exit the Parameter Editor. If you select CANCEL, all modifications are discarded and the original parameter settings of the ion chamber remain. If you select OK, the ion chamber parameters (modified or not) are sent to the instrument where they are stored for use during measurement modes.

NOTE

When Ion Chambers are edited, deleted, inserted, or appended the List box background color will change from ‘white’ to ‘yellow’ indicating that the Dosimeter’s settings have been modified. Permanent storage in the Dosimeter’s memory is made only after depressing the STORE button or by selecting one of the following menu items: BIAS SETTINGS, SPECIAL ITEMS, MEASUREMENT DISPLAYS, or TIMER INTERVALS. Storage in memory may take up to 70 seconds.

APPEND

If you want to add an ion chamber to the end of the list of ion chambers, click on APPEND. The Program Ion Chamber Form appears with the default text and values. Change the text and values to match those of the ion chamber you are adding. Select OK to send the new ion chamber to the Model 35040 Therapy Dosimeter; select CANCEL to discard the ion chamber and stop the append operation.

DELETE

If you want to delete an ion chamber, select it from the List Box. When you click on DELETE, you are asked to confirm the deletion. Select YES to delete the ion chamber; select NO to stop the delete operation.

INSERT

If you want to insert an ion chamber, select a position in the List Box ahead of which to insert a new ion chamber. Click on INSERT. The Program Ion Chamber Form appears with the default text and values. Change the text and values to match those of the ion chamber you are adding. Select OK to send the new ion chamber to the Model 35040 Therapy Dosimeter; select CANCEL to discard the ion chamber and stop the insert operation.

STORE

Click on STORE so that changes made to the instrument’s ion chamber list are stored permanently. This process may last 70 seconds.

NOTE

If changes were made to the ion chamber list and not stored permanently with the STORE button, they are permanently stored when another customization form is selected.
