#61-183 Alligator Clip Adapter
This adapter allows the SureTest to analyze non-outlet based circuits for branch circuit
safety and performance. Simply plug the alligator clip adapter into the IEC connection on the front
of the SureTest. Then, properly connect the hot (black), neutral (white) and ground (green) alliga-
tor clips onto the circuit. Correct test results are dependent on making good connections with the
alligator clips onto the circuit.
WARNING: The SureTest is designed for 120VAC circuits only. Do not exceed the
rating of the SureTest with this adapter.
This adapter also allows the operator to use the SureTest (#61-165 only) to verify AFCI
protection on non-outlet based circuits in bedrooms, such as on circuits used for lighting, ceiling
fans, and smoke detectors.
#61-175 Ground Continuity Adapter
This adapter allows the operator to verify that a cabinet or equipment chassis has been properly
bonded to the system ground. Plugging the SureTest into the ground continuity adapter isolates
the SureTest from the electrical ground. If the equipment is properly grounded, then connecting the
alligator clip from the ground continuity adapter to the cabinet or equipment chassis should pro-
vide a pathway to ground, and consequently a normal wiring condition on the SureTest.
After the ground continuity adapter has been connected, the SureTest can be used to measure the
ground impedance of the cabinet or equipment chassis back to the panel. See the section on Line
Impedance Measurements for test instructions for ground impedance.
