Operation
1. Refer to “Typical Measurements”for specific
measurement instructions.
2. Test the unit on a known functioning circuit or
component.
•If the unit does not function as expected on a
known functioning circuit, replace the battery.
•If the unit still does not function as expected, send
the unit to Greenlee for repair.
3. Take the reading from the circuit or component to be
tested.
4. If the tester is used in a noisy environment, ensure
that the sound level of the tester is perceptible.

•This test is not always appropriate for testing whether a
circuit is not live (off). To determine whether the circuit
is not live, use both probes L1 and L2.
•Firmly grasp the insulated grips of the tester to increase
the sensitivity of this test.
Note: Standing on wooden steps, ladders, or insulated
floor coverings can impair single-pole voltage detection.
Unfavorable lighting conditions, such as direct sunlight,
or a non-operational, grounded AC system can also
impair detection.

Phase Rotation Test (cont’d)
The phases are identified with at least three different
conventions:
•L1, L2 and L3
•A, B and C
•R, S and T
The phase sequence function of the GT-55e and GT-85e
can determine the phase relationship between two AC
voltages.
1. Connect L1 and L2 to two of the phases. Firmly grasp
the insulation grips of the tester to increase the
sensitivity of this test. Compare the result on the
display with the “Phase Sequence Table.”
Phase Sequence Table
2. If the phase rotation is counterclockwise , switch
the wires to produce a clockwise rotation.
Note: Ensure that the test electrodes (probe tips) make
good contact with two phases of a three-phase mains
while testing the phase rotation. For absolute determina-
tion of a clockwise rotation, it is necessary to reverse the
position of the two probes and verify that the phase
indication changes. The indication or can be affected
by unfavorable light conditions, by protective clothing, or
in insulated locations.

RCD Trip Test
During voltage tests in systems equipped with RCD circuit
breakers, a RCD switch can be tripped at a nominal
residual current of 10 mA or 30 mA by measuring the
voltage between L and PE.
The GT-55e and GT-85e are equipped with an internal load
enabling the tripping of an RCD protection device of 10 mA
or 30 mA.
Note: To prevent tripping an RCD, charge the unit first by
connecting the probes between L and N for approximately
5 seconds. Immediately afterwards, connect the probes
between L and PE.
