the push button switch will flash to show that the
test is in progress. The digital-display will
indicate the test number of the current circuit
under test. Should a failure be present, the
flashing light will turn to a steady glow 20
seconds after the failure is detected. Bite test
numbers 0, 1, 2, and 3 are bite tests allocated to
