The Voltage (V) menu displays the True RMS line voltage in real-time. This main menu has
a sub-menu positioned horizontally at the bottom of the screen that displays the line voltage
(RMS HN), ground-to-neutral voltage (RMS GN), Peak voltage (Peak), and Frequency
(Hz). To navigate through the submenu, use the side arrow button (
The Voltage Drop (V

The ASCC screen displays the Available Short-Circuit Current that the branch circuit can
deliver through the breaker during a bolted fault (dead-short) condition.
The Impedance (Z) main menu displays the impedance in ohms (Ω) of the hot conductor.
This main menu has a sub-menu positioned horizontally at the bottom of the screen that

GFCI Test Button
Depressing this button displays the GFCI main menu. Two tests can
be performed in this menu: GFCI and EPD. The GFCI tests Ground
Fault Circuit Interrupting devices by faulting 6-9mA from hot-to-
ground per UL-1436. The EPD tests those breakers, which have an
Equipment Protective Device feature that trips the breaker if a ground fault of greater than 30mA
is detected. Pressing the side arrow button (
desired test is highlighted, depress the GFCI test button on the keypad to activate the test.
AFCI Test Button
Depressing this button displays the AFCI main menu. Two tests
can be performed in this menu: AFCI and NEUT. The AFCI tests
Arc Fault Circuit Interrupting devices by creating a 106-141 amp
short-duration arc between the hot and neutral conductors per
UL1436. The NEUT tests for a Shared Neutral or falsely grounded neutral conductor,
which causes AFCI breakers to nuisance trip with normal loads. This test applies 300mA
between hot and neutral to ensure that the AFCI breaker does not trip.

Testing Procedure
Wiring Verification
Immediately after being inserted into a receptacle, the
SureTest displays the IDEAL logo while it performs a battery
of tests. The first test result displayed is the wiring condition.
The SureTest checks for the following conditions and indicates the test result on
the display.
Wiring Condition
Display Indication
H G N
Correct Wiring
No Ground
Polarity Reversal
Open/Hot Neutral
False Ground
F
If the wiring condition is other than normal, the SureTest is limited on its
measurements that can be performed. If a no ground condition exists, only the
line voltage and voltage drop measurements are available. In a hot/ground rever-
sal, open neutral or open hot condition, the unit will not have any power so the
display will be blank.
Notes:
1) Will not detect two hot wires in a circuit.
2) Will not detect a combination of defects.
3) Will not detect reversal of grounded and grounding conductors.
False Ground Indication
NEC article 250-23(a) only allows for a neutral-to-ground bond to occur at the
main panel. The SureTest suggests any improper neutral-to-ground bonds within
15-20 feet upstream (towards the panel) of the tester. If this bond improperly
occurs in the branch circuit through a bootleg ground via a jumper wire at the outlet
device or inadvertent contact of the ground wire to the neutral connection, the
SureTest indicates a false ground condition. Note that if the SureTest is within 15-
20 feet of the main panel, the unit will indicate a false ground condition on a prop-
erly wired circuit due to its close proximity to the proper ground-neutral bond in the
main panel.
