Checking the Dose Rate
- 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 - 5 x factor 10, i.e. by - 50.
- Click Set Value after entering 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.
