I. GFCI Testing
The SureTest applies 6mA through a fixed resistor to trip the GFCI. A
functional GFCI will disconnect the power. The reset button for the GFCI
may be at the receptacle or at the panel.
To activate the GFCI test, press the GFCI button (GFCI) from anywhere
within the measurement menu. The actual current being bled from hot to
neutral will be displayed. (6mA is the nominal current sent through the fixed
resistor. The actual current will vary depending on the line voltage per UL
1436.) Test in progress will than appear on the display to let the user know
that the GFCI test is being performed. The unit will bleed the current until the
GFCI trips, or up to 6 seconds.
If the GFCI device is functioning properly, it will disconnect power, and the
display on the unit will go out. When the circuit is reset and power is
restored, the unit will display the actual time that the GFCI took to trip the
circuit. Pressing the down arrow button (
↓
) resets the unit and returns it to
the wiring verification mode.
If the GFCI fails to trip, the SureTest will show invalid on the display
indicating that the GDCI may be installed incorrectly or the GFCI may be
defective.

NOTE:
The SureTest will not allow the GFCI test if a no ground condition exists.
Repair the ground circuit before testing.
NOTE:
In order to test GFCI’s in a 2-wire system (no ground), the # 61-175
ground continuity adapter must be used. Connect the alligator clip on the
adapter to a ground, such as a metal water or gas pipe.
