Optional Accessories
#61-175 Ground Continuity Adapter
This adapter allows the operator to verify that a cabinet or equipment chas-
sis has been properly bonded to the system ground. Plugging the SureTest
into the ground continuity adapter will isolate the SureTest from the electri-
cal ground. If the equipment is properly grounded, then connecting the alli-
gator clip from the ground continuity adapter to the cabinet or equipment
chassis should provide 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.
See the section on Line Impedance Measurements for test instructions.
This adapter can also be used to test GFCI receptacles on 2-wire circuits.
Connect the alligator clip on the adapter to a ground, such as a metal water
or gas pipe prior to testing the GFCI.
#61-176 Isolated Ground Adapter
This adapter allows the operator to verify that a receptacle is completely iso-
lated from the system ground that is bonded to other devices on the branch
circuit.
Test the ground impedance of the receptacle and make a note of the results
(See the section on Line Impedance Testing for details). Remove the
SureTest and plug it into the isolated ground adapter. Attach the alligator
clip to the center receptacle screw or metal junction box, and re-insert the
SureTest into the receptacle and make a note of the result.
The isolated ground adapter creates a parallel pathway to ground, which
results in a lower reading on a receptacle with an isolated ground. If the
two readings are the same, than the receptacle does not have an isolated
ground. If the reading taken with the isolated ground adapter is lower, than
the receptacle has an isolated ground.

#61-183 Lighting Circuit Adapter
This adapter allows the operator to use
the SureTest on residential lighting cir-
cuits to verify that bedroom lighting cir-
cuits are protected by the AFCI (61-155
only), and identify and locate high resis-
tance points within the circuits.
Simply plug the lighting circuit adapter into the IEC connection on the top
of the SureTest, and connect the hot (red), neutral (white) and ground
(green) alligator clips onto the circuit. Correct test results are dependant on
making good connections with the alligator clips onto the circuit.
Note: The SureTest is designed for 120V circuits only. Do not exceed the
rating of the SureTest with this adapter.
