Tests
- AUTOMATIC TESTS
This is the type of test described in the Initial Operation and Routine Operation portions of this manual.
An internal timer has been set to conducts tests automatically at intervals ranging from 1 minute to 24 hours.
- MANUAL TESTS
Tests may be conducted manually, thus temporarily overriding the timer (automatic) setting. This allows a test to
be conducted at will without waiting for the next test interval or having to change the timer setting. To manually
conduct a test, depress the Op Mode button several times as needed until the “Single Check” or “All Check”
menu appears in the display, then depress ENTER. Automatic operation will resume after the manual test has
been completed.
