breaker under test. The breaker must trip. If it does
not – do not use the breaker – consult an electrician.
Main Screen
Line 1: shows an unloaded voltage of 121.5V /
60Hz at the outlet being tested.
Line 2: shows the polarity status
Line 3: The "SET LOAD" switch is set for a test
drawing 15 amps. At 15 amps of current draw, the
voltage at the outlet would drop by 4.2%. Since
4.2% is lower than the NEC recommendation of a
maximum of 5% drop, it would not be flashing.
Line 4: shows that 1.1% of the voltage drop is on
the hot conductor while 3.1% is on the neutral
conductor.
Line 5: shows that the voltage at the outlet would
drop to 116.4 volts with a 15 amp load applied.
Line 6: shows that the resistance of the ground
conductor from the outlet to the point where it is
bonded to the neutral conductor is .27 ohms.
NOTE: The Set Load switch may be changed to
show what the drops and voltage would be at 10,
15, or 20 Amps any time after the first reading is
indicated.
Secondary Screen
Line 1: shows the outlet to have a true rms voltage
of 121.5/60 Hz volts with no load applied by The
Inspector-3.
Line2: shows the polarity status
