How to execute a P.V. test
The Technician or Application Admin user can execute a Performance Verification (P.V.)
When to perform a P.V. test
There are two ways to perform a P.V. test in DoseControl:
1️⃣ On Demand Users can perform a P.V. test on-demand at any time directly from the P.V. Module main screen.
2️⃣ Timer Prompt The App Admin can set the “frequency” timer in the P.V. Method configuration so that a P.V. test must occur at a specific frequency (e.g. every 24 hours). When the timer expires, the software will automatically prompt the user to execute a P.V. test. The user will not be able to proceed to measuring dosimeters until the P.V. is complete and the reader passes the test. See About P.V. test frequency
