If you are connected to a RadStar Alpha Series device that has completed tests stored on its hard drive, you can use the Completed Tests feature to view tests that are on the device. Each RadStar Alpha Series will store up to 5 tests on its local hard drive. If you already have 5 tests in the local storage, the mobile app will prompt you to delete an old test before you can start a new test. NOTE: You can only delete tests that have been successfully synced to the Radon Management Cloud.
