Introduction

Utilizing patented technology, the SureTest® circuit analyzers

“look behind walls” to identify wiring problems that can lead to

personal shock hazards, electrical fires, or equipment performance issues. Personal shock hazards

stem from poor grounding, false grounds, and/or no ground fault protection. Electrical fires are

primarily caused from arc faults and high resistance points that lead to glowing connections in the

circuit wiring. And, equipment performance issues arise due to insufficient voltage available under

load, poor ground impedance, and high ground-to-neutral voltage. In fact, it’s estimated that 80%

of power quality performance issues are related to the faulty wiring issues stated above.

General Operation

The SureTest

®

Circuit Analyzer takes only seconds to test each outlet and circuit under a short

duration rated load. This test tool checks for various wiring conditions including: correct wiring,

polarity reversal and no ground per UL-1436. A simple menu gives access to measurements of line

voltage, voltage drop under a full load condition, ground-neutral voltage and line impedances. The

ground fault circuit interrupter (GFCI) test is performed separately in accordance with UL-1436 and

disrupts the electrical supply if a functional and grounded GFCI is present.

Note: References to the 61-165 SureTest with AFCI is for informational purposes for legacy users of

this model. This model is no longer available. The SureTest

circuit interrupter (AFCI) devices to ensure that AFCI breakers protecting the circuit have been

installed correctly. This test disrupts the electrical supply if a functional AFCI is present. This tool

also checks for a shared neutral condition that leads to AFCI nuisance tripping.

To maintain stated accuracies during repeated use, allow 20 seconds between insertions to

adequately dissipate any heat buildup during the load testing.

Menu Navigation

The microprocessor’s top priorities are to take live measurements and then analyze the data.

Hence, the microchip occasionally will not recognize the keypad buttons being rapidly depressed,

while it’s executing these routines. To avoid this issue, hold down the keypad button each time

until the menu changes.

The measurements taken by the SureTest are broken into five main menus positioned down the

left side of the display: Wiring Configuration (•••), Voltage (V), Voltage Drop (VD), Amperage

(A), and Impedance (Z). To navigate to each of the main menus, use the down arrow button ( ).

The Wiring Configuration (•••) screen indicates correct wiring, reverse polarity, hot/

ground reversal and no ground conditions by sequencing the three balls. The label on the back of

the product explains the wiring sequence indications.

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 (VD) screen dual displays percent voltage drop with a 15 amp load along with

the resultant loaded voltage (VL). This main menu has a submenu, which also displays the

percent voltage drop and loaded voltage with 20 amp and 12 amp loads. To navigate through the

submenu, use the side arrow button ( ).

WARNING: Do not use on outputs from UPS systems, light dimmers or square

wave generating equipment as damage to the analyzer will occur.

The Amperage (A) menu displays the Estimated Load on Line (ELL) in real-time and holds the

maximum amperage in the upper right of the display. The main menu has a submenu positioned

horizontally which displays (ASCC1), Available Short-Circuit Current from H-N and (ASCC2)

Available Short Circuit Current H-N-G. To navigate through the submenu, use the side arrow

button. ( )

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 also displays

the neutral (N) and ground (G) conductor impedances. To navigate through the submenu, use the

side arrow button ( ). Note that testing the ground impedance will trip a GFCI protected circuit.

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 ( ) navigates between these two tests. Once the 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.

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 reversal, 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.

4) For individual conductor impedance, refer to page 7.

False Ground Indication

The SureTest indicates when a false ground condition exists from an improper bond

via a bootleg (ground jumper wire at the outlet device) or inadvertent contact of the

ground wire to the neutral connection. Note that if the SureTest is within 15-20 feet

of the main panel, the unit will indicate a false ground condition on a properly wired

circuit due to its close proximity to the proper ground-neutral bond in the main panel.

If necessary, simply use a 3 conductor extension cord that is 20 feet long to make the

measurements.

Voltage Measurements

The line voltage measurement should be 120VAC +/-10% fluctuation at 60 Hz. The peak voltage

should be 1.414 times the rms line voltage reading for a clean sine waveform. Ground-to-neutral

voltage should be less than 2 VAC. In a single-phase circuit, a higher ground-neutral voltage

indicates excessive current leakage between the neutral and ground conductors. In a 3-phase

circuit with a shared neutral, a high ground-neutral voltage could indicate an unbalanced load

between the three phases or harmonic distortion on the shared neutral. Excessive ground-neutral

voltage may result in inconsistent or intermittent equipment performance.

Troubleshooting Tips for Voltage Issues

Voltage Drop (VD) Measurements

The SureTest measures the line voltage, applies a load on the circuit, measures the loaded voltage,

then calculates the voltage drop. Results are displayed for 12A, 15A, and 20A loads. The National

Electrical Code recommends 5% as the maximum voltage drop for branch circuits for reasonable

efficiency (NEC article 210-19. FPN 4). And, the voltage under load (VL) should not drop below

108VAC for reliable equipment operation.

A good branch circuit should start out with less than 5% voltage drop at the furthest receptacle

from the panel at the end of the cable run. Then, each receptacle tested in sequence towards the

panel should show a steady decrease in voltage drop. If the voltage drop is above 5% and does

not noticeably decrease as you get closer to the first device on the circuit, then the problem is

between the first device and the panel. Visually check the terminations at the first device, the wir-

ing between the device and the panel, and the circuit breaker connections. High resistance points

can usually be identified as hot spots using an infrared thermometer or by measuring the voltage

W

ARNING: Do not exceed the unit’s maximum voltage rating of 250VAC. The

SureTest is rated for use at 120 and protected to 250 volts in case of miswired circuits.

Immediately unplug the unit and do not press any buttons if 240 volts is displayed.

panel, the circuit may have undersized wire, too long of a cable run, or too much current on the

circuit. Check the wire to ensure that it is sized per code and measure the current on the branch

circuit. If a voltage drop reading changes significantly from one receptacle to the next, then the

problem is a high impedance point at or between two receptacles. It is usually located at a termi-

nation point, such as a bad splice or loose wire connection, but it might also be a bad receptacle.

Estimated Load on Line (ELL) Measurement

The SureTest estimates the load on a branch circuit to provide an indication of how much capac-

ity in the circuit remains or to quickly check if the circuit is dedicated. This function is a rough

estimate (no stated accuracy), as accurately measuring circuit current has to be done with a clamp

meter at the electrical panel. The proprietary way in which these calculations are made allows the

user to plug the unit into an outlet and quickly determine the current load on that branch circuit.

Both the distance of the SureTest from the load and branch circuit impedance will affect accuracy.

Best accuracy is obtained by positioning the SureTest in the same outlet as the largest load on

line; otherwise, try to position the SureTest between the load(s) and the electrical panel. The maxi-

mum amperage reported by the tester is 15A.

ASCC Measurement

The SureTest calculates the Available Short-Circuit Current (ASCC) that the branch circuit can

deliver through the breaker during a bolted fault (dead-short) condition.

The ASCC is calculated by dividing the line voltage by the circuit’s line impedance (hot + neutral).

Depressing the side arrow ( ) displays the worst-case scenario where all three conductors (hot,

neutral, ground) are shorted together -- the neutral and ground provide a lower impedance via

a parallel return path. Note that this second test will trip a GFCI. See the following equations for

clarification.

ASCC1 = Line Voltage (VHN)/ (Hot Ω + Neu Ω)

ASCC2 = Line Voltage (VHN)/ (Hot Ω + 1/(1/Neu Ω+ 1/ Grd Ω)

Voltage Drop <5% High Voltage

Impedance (Z) Measurements

If the voltage drop measurement exceeds 5%, analyze the hot and neutral impedances. If one is

significantly higher than the other, the problem is with the conductor with the much higher imped-

ance. Then, check all connections on that conductor back to the panel. If both impedances appear

high, the source can be undersized wire for the length of run, a bad device, or poor connections at

the pigtails, devices, or panel.

The ground impedance measured should be less than 1 ohm as a rule of thumb to ensure that

fault current has a sufficient path back to the panel. IEEE states the ground impedance should be

less than 0.25 ohms to ensure the ground conductor can safely return any fault current which

could damage equipment on the circuit. Surge suppression systems require a good ground to

adequately protect equipment from transient overvoltages. Note that a current is applied to the

ground conductor to accurately measure its impedance. By the inherent nature of this test, a GFCI

protected circuit will trip unless the device is temporarily removed from the circuit. Due to the

ground impedance test inducing current on the ground conductor, this tester must not be used in

active paitent care areas or in situations where people may be connected through devices to the

electrical grounding system such as ESD strap protection or medical equipment.

GFCI Testing

To test the GFCI device, the SureTest

®

creates an imbalance between the hot and neutral conduc-

tors by leaking a small amount of current from hot to ground using a fixed value resistor. The test

current applied by the SureTest

®

should not be less than 6mA or greater than 9mA per UL-1436.

A functional GFCI should sense the imbalance and disconnect the power. The SureTest displays

To conduct a GFCI test, press the GFCI button to enter the GFCI main menu. The GFCI symbol in

the display should be highlighted as the default test. If EPD is lit, then use the side arrow ( )

to highlight the GFCI symbol. Then, press the GFCI button to activate the test. The actual current

being leaked to ground is displayed. The TEST icon and hourglass symbol appear on the display

to let the user know that the GFCI test is being performed. The GFCI device should trip within the

UL established guideline causing the display to blank out with the loss of power. When the GFCI

device is reset, the unit displays the actual trip time that the GFCI took to respond to the current

imbalance and open the circuit. Pressing the down arrow button ( ) returns it to the wiring veri-

fication mode. If the GFCI fails to trip, the SureTest terminates the test after 6.5 seconds. Further

inspection should determine whether the GFCI circuitry is faulty, the GFCI is installed incorrectly,

or if the circuit is protected by a GFCI device.

UL Guideline

for trip time:

Notes:

1) In order to test a GFCI 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 source, such as

to a metal, water or gas pipe.

2) All appliances or equipment on the ground circuit being tested should be unplugged

to help avoid erroneous readings.

In addition to performing a GFCI test for evaluating personal protection from shock hazards, the

SureTest can also conduct testing to ensure equipment protection from ground faults exceeding

30mA. The method of operation is the same as the GFCI test noted in the first paragraph above

but uses a different resistor to create a 30mA leakage current from hot-to-ground. To conduct an

EPD test on an Equipment Protective Device, press the GFCI button to enter the GFCI main menu.

The GFCI symbol in the display should be highlighted as the default test. Press the side arrow

actual current being leaked to ground is displayed. The TEST icon and hourglass symbol appear

on the display to let the user know that the EPD test is being performed. The EPD should trip

causing the display to blank out with the loss of power. When the EPD is reset and power is

restored, the unit displays the actual trip time that the EPD took to respond to the current imbal-

ance and open the circuit. Pressing the down arrow button ( ) returns it to the wiring verification

mode. If the EPD fails to trip, the SureTest terminates the test after 6.5 seconds. Further inspection

should determine whether the EPD circuitry is faulty, the EPD is installed incorrectly, or if the

circuit is protected by an EPD.

AFCI Testing (#61-165 only)

The SureTest

®

w/AFCI applies 8-12 current pulses in less than a half second across hot-to-neutral

with each pulse no longer than 8.3ms in duration, and having an amplitude of 106-141 amps in

accordance with UL1436. A functional AFCI breaker should recognize these current pulses as a

dangerous arc and disconnect the power to the circuit. To restore power, reset the breaker at the

panel.

To properly test the AFCI, execute the following steps:

1) Consult the AFCI manufacturer’s installation instructions to determine that the AFCI is installed

in accordance with the manufacturer’s specifications.

2) Plug in the SureTest and check for correct wiring of receptacle and all remotely connected

receptacles on the branch circuit. Then, go to the panel and operate the test button on the AFCI

installed in the circuit. The AFCI must trip. If it does not, do not use the circuit - consult an

electrician. If the AFCI does trip, reset the AFCI.

3) Return to the tester and press the AFCI button on the tester to enter the AFCI main menu. The

AFCI symbol in the display should be highlighted as the default test. If NEUT is lit, then use

the side arrow ( ) to highlight the AFCI symbol. Then, press the AFCI button to activate the

test. The TEST icon and lightning bolt symbol light brightly on the display to let the user know

that the AFCI test is being performed. The AFCI device should trip causing the display to blank

out with the loss of power. If the AFCI fails to trip, the SureTest

®

will not lose power and the

display shows a dimly lit lightning bolt. This non-trip condition would suggest:

a) A wiring problem with a totally operable AFCI, or

b) Proper wiring with a faulty AFCI.

Consult with an electrician to check the condition of the wiring and AFCI.

4) CAUTION: AFCIs recognize characteristics unique to arcing, and AFCI testers produce charac-

teristics that mimic some forms of arcing. Because of this, the tester may give a false indication

that the AFCI is not functioning properly. If this occurs, recheck the operation of the AFCI

using the test and reset buttons. The AFCI’s test button function should demonstrate proper

operation.

Note: The AFCI circuitry is protected by a thermal sensor to assure long life. If a

thermometer icon appears in the display during repeated AFCI testing, the sensor delays fur-

ther testing until the circuitry cools. At that point, the testing will automatically

continue.

Shared Neutral Test (#61-165 only)

AFCI breakers are prone to nuisance tripping when wired with a shared neutral or when the neutral

conductor is accidentally grounded before the panel. The AFCI tripping occurs because it senses

an imbalance between the current going out on the hot and the current returning on the neutral.

A shared neutral between two hot conductors creates this imbalance. See the illustration below to

see how this imbalance can occur.

The SureTest can test for these conditions by applying a small load of 300mA between hot and

neutral to simulate a normal load and ensure that the AFCI breaker does not trip. To conduct a

shared neutral test, press the AFCI button to enter the AFCI main menu. Press the side arrow ( )

to highlight the NEUT symbol. Then, press the AFCI button to activate the test. The TEST icon will

light brightly while the test is being conducted. The AFCI breaker should not trip. If the breaker

does trip, a shared neutral is the probable cause.

#61-183 Alligator Clip Adapter

This adapter allows the SureTest to analyze non-outlet based circuits for branch circuit

safety and performance. Simply plug the alligator clip adapter into the IEC connection on the front

of the SureTest. Then, properly connect the hot (black), neutral (white) and ground (green) alliga-

tor clips onto the circuit. Correct test results are dependent on making good connections with the

alligator clips onto the circuit.

WARNING: The SureTest is designed for 120VAC circuits only. Do not exceed the

rating of the SureTest with this adapter.

This adapter also allows the operator to use the SureTest (#61-165 only) to verify AFCI

protection on non-outlet based circuits in bedrooms, such as on circuits used for lighting, ceiling

fans, and smoke detectors.

#61-175 Ground Continuity Adapter

This adapter allows the operator to verify that a cabinet or equipment chassis has been properly

bonded to the system ground. Plugging the SureTest into the ground continuity adapter isolates

the SureTest from the electrical ground. If the equipment is properly grounded, then connecting the

alligator clip from the ground continuity adapter to the cabinet or equipment chassis should pro-

vide 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 back to the panel. See the section on Line

Impedance Measurements for test instructions for ground impedance.

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 isolated from the system

ground that is bonded to other devices on the branch circuit. Test the ground impedance of the

receptacle and record the ohms value. (See the section on Line Impedance Testing for details on

obtaining the ground impedance value). 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 record the ohms value.

The isolated ground adapter creates a parallel pathway to ground, which results in a lower ground

impedance reading with the adapter versus with the receptacle with the isolated ground. If the two

readings are the same, then the receptacle does not have an isolated ground. If the reading taken

with the isolated ground adapter is lower, then the receptacle has an isolated ground.

Gracias a su tecnología patentada, los analizadores de circuitos

SureTest® “ven a través de las paredes” para identificar problemas

de cableado que pueden causar riesgos de descarga eléctrica a las

personas, incendios o problemas en el funcionamiento de los

equipos. Los riesgos personales de descarga eléctrica se originan en conexiones a tierra

incorrectas, tierras falsas y/o ausencia de protección contra fallas de tierra. Los incendios

eléctricos se producen como consecuencias de fallas de arco y puntos de alta resistencia

que crean fuego en las conexiones del cableado del circuito. Finalmente, los problemas de

funcionamiento de los equipos surgen debido a la insuficiencia de la tensión disponible en

carga, una impedancia a tierra deficiente y una alta tensión de tierra a neutro. Como dato,

se estima que el 80% de los problemas de la calidad del suministro eléctrico se relacionan

con las fallas del cableado arriba indicadas.

Operación en general

El analizador de circuito SureTest® toma solo unos segundos para probar cada salida y cir-

cuito con una carga nominal de corta duración. Esta herramienta de prueba comprueba diver-

sas condiciones del cableado, que incluyen: corrección del cableado, inversión de polaridad

y falta de tierra según norma UL-1436. Un sencillo menú permite acceder a las mediciones

de tensión de línea, caída de tensión en condiciones de plena carga, tensión tierra-neutro

e impedancias de línea. La prueba del interruptor de circuito de falla a tierra (GFCI, por sus

siglas en inglés) se realiza por separado de acuerdo con UL-1436 e interrumpe el suministro

eléctrico si está presente un GFCI funcional y conectado a tierra.

Nota: Las referencias al SureTest® 61-165 con AFCI son para fines informativos para usu-

arios legacy de este modelo. Este modelo ya no está disponible. El instrumento SureTest®

con AFCI, Nº 61-165, prueba también dispositivos disyuntores por falla de arco (AFCI)

para asegurar que dichos dispositivos de protección de circuitos hayan sido instalados

correctamente. Esta prueba interrumpe el suministro eléctrico si hay presente un AFCI en

funcionamiento. La herramienta comprueba también las condiciones de neutro compartido

que originan disparos de AFCI injustificados.

Para mantener las precisiones indicadas durante el uso repetido, espere 20 segundos entre

inserciones para disipar adecuadamente cualquier acumulación de calor producida durante

la prueba bajo carga.

Navegación por los menús

Las máximas prioridades del microprocesador son tomar mediciones en vivo y luego anali-

zar los datos. Por lo tanto, ocasionalmente el microchip no reconoce los botones del teclado

que se pulsan rápidamente, mientras está ejecutando estas rutinas. Para evitar este prob-

lema, mantenga oprimido el botón del teclado cada vez, hasta que cambie el menú.

Las mediciones tomadas por el SureTest se dividen en cinco menús principales que se

ubican en el costado izquierdo de la pantalla: Configuración de cableado (•••), Tensión

(V), Caída de tensión (VD), Corriente (A) e Impedancia (Z). Para navegar a cualquiera de los

menús principales, use el botón de flecha abajo ( ).

La pantalla de configuración del cableado (•••) indica la corrección del cableado y las

condiciones de inversión de polaridad, inversión de vivo/neutro y falta de tierra, efectuando

una secuencia con los tres círculos. El rótulo del dorso del producto explica las indicaciones

de la secuencia del cableado.

El menú de tensión (V) muestra el valor eficaz (RMS) de la tensión de línea en tiempo real.

Este menú principal tiene un submenú ubicado horizontalmente al pie de la pantalla, que

muestra la tensión de línea (RMS HN), la tensión de tierra a neutro (RMS GN), la tensión

pico (Peak) y la frecuencia (Hz). Para navegar por el submenú, use el botón de flecha lat-

eral ( ).

La pantalla dual de caída de tensión (VD) muestra la caída de tensión porcentual con una

carga de 15 A, junto con la tensión en carga resultante VL). Este menú principal tiene un

submenú, que muestra también la caída de tensión porcentual y la tensión en carga con

cargas de 20 y 12 A. Para navegar por el submenú, use el botón de flecha lateral ( ).

El menú Corriente (A) muestra la carga estimada en línea (ELL) en tiempo real y retiene la cor-

riente máxima en la parte superior derecha de la pantalla. El menú principal tiene un submenú

posicionado horizontalmente que muestra (ASCC1), la corriente de cortocircuito disponible

entre vivo y neutro (H-N) y (ASCC2), la corriente de cortocircuito disponible en vivo, neutro y

tierra (H-N-G). Para navegar por el submenú, use el botón de flecha lateral ( ).

El menú principal de impedancia (Z) muestra la impedancia en ohmios (Ω) del conductor

vivo. Este menú principal tiene un submenú ubicado horizontalmente al pie de la pantalla,

que muestra también las impedancias de los conductores neutro (N) y de tierra (G). Para

navegar por el submenú, use el botón de flecha lateral ( ). Tenga en cuenta que la prueba

de impedancia a tierra hará disparar un circuito protegido por un GFCI.

Botón de prueba de GFCI

Al oprimir este botón se muestra el menú principal de GFCI. Es

posible realizar dos pruebas en este menú: GFCI y EPD. La prueba

de GFCI verifica los dispositivos disyuntores diferenciales por falla

de tierra enviando del vivo a tierra 6-9 mA según norma UL-1436. La

prueba EPD es para probar los disyuntores que tienen una características de dispositivo protec-

tor de equipos (EPD) que dispara el disyuntor si se detecta una falla de tierra superior a 30 mA.

Oprimiendo el botón de flecha lateral ( ) se navega entre estas dos pruebas. Una vez resaltada la

prueba deseada, oprima el botón de prueba de GFCI del teclado para activar la prueba.

Botón de prueba de AFCI

Al oprimir este botón se muestra el menú principal de GFCI. Es

posible realizar dos pruebas en este menú: AFCI y NEUT. La

prueba de AFCI comprueba los dispositivos disyuntores por falla

de arco creando un arco de corta duración de 106-141 A entre los

conductores vivo y neutro según norma UL1436. La prueba NEUT comprueba si existe un

conductor neutro compartido o falsamente puesto a tierra, lo que causa que los disyuntores

AFCI produzcan disparos injustificados con cargas normales. En esta prueba se aplican 300

mA entre el vivo y el neutro para asegurar que el disyuntor AFCI no se dispare.

Procedimiento de las pruebas

Verificación del cableado

Inmediatamente después de ser insertado en un receptáculo el instrumento

SureTest muestra el logotipo de IDEAL mientras realiza una bat-

ería de pruebas. El primer resultado de prueba mostrado es el

estado del cableado. SureTest comprueba las siguientes condi-

ciones e indica los resultados de la prueba en la pantalla.
