MEASURING VOLTAGE
Apply test leads to the system under test to measure voltage; the
LED's will light up indicating the voltage present. When DC voltage
is detected the + or – polarity indicator will illuminate revealing
the polarity. When AC voltage is detected, both + and – polarity
indicators will be illuminated at the same time.
NOTE: Test-leads seated in the lead holders on the back of the ET60
are spaced correctly to test tamper-resistant US-style outlets.
GHOST/STRAY VOLTAGES
The low input impedance of ~16kΩ reduces the possibility of falsely
reading ghost or stray voltages on non-energized circuits.
GFCI TESTING
Check the GFCI device user manual for more information.
Always contact a qualified electrician to resolve wiring problems.
Operate the test button on the GFCI device. If the GFCI circuit does
not trip, the device is not functioning properly.
To test the functionality of a GFCI-protected device, apply leads to the
hot/live and ground terminals for 7 seconds.
To resolve wiring or GFCI concerns, contact a qualified electrician.
CAUTION: The maximum testing voltage is 600V. Voltages in
excess of 600V will illuminate the 600V LED indicator. No other
warnings will be delivered for voltages above 600V. Testing voltages
above 600V should not be attempted under any circumstances.

OPERATING INSTRUCTIONS
• If the GFCI device is functioning properly,
the GFCI will trip and the circuit will become
de-energized. The ET60 tester will stop
indicating voltage.
• If the GFCI device is not functioning properly,
the power to the circuit will remain and the
ET60 will continue to indicate voltage
Measuring above 240V
should be limited to
30 seconds continuous,
followed by a recommended
recovery time of at least
240 seconds (4 minutes).
