2.6 Test
A simple manual test of the F10 is achieved by pressing the TEST button.
When pressed the LED will flash, however the output contacts will not operate.
This simple test proves the processor, LED, test button and battery are
healthy. It does not test the integrity of the CT connections or output
contacts.
A primary injection into the CT arrangement is the best local test available.
Nortech supply a portable battery powered test set for this purpose.
