a) Operating Voltage Source

The Hook is designed for use in 12 to 48 VDC electrical sys-

tems and comes supplied with a 20 ft., 10-gauge coax cable

and 2 heavy-duty battery hook-up clips.

b) Connecting to the Vehicle’s Battery

(Voltage Source)

Connect the red clip to the positive terminal of the vehicles

battery source and the black clip to negative or ground. The

Hook start-up tone will sound and the indicator light on the Y-

Connector with Battery Clips will illuminate. This tells you that

the Hook is connected correctly and the internal fuse of the

Y-battery-clip-connector is working properly.

c) Y-Connector with Battery Clips

The Y-Connector with Battery Clips has a safety fuse built into

it. The built-in fuse will blow in the event the 10-gauge coax

power cable gets clamped or pinched in a door or hood caus-

ing a short circuit.

Note: If the Y-Connector with Battery Clips does not light when

properly connected to the voltage source, you probably have a

damaged 10 gauge coax power cable. It is recommended that

the cable be inspected and tested before replacing a new Y-

Connector with Battery Clips.

Contact your distributor or Power Probe, Inc. for a replacement.

d) Auxiliary Ground Lead

The auxiliary ground lead provides ground to circuits and com-

ponents that are not connected to ground. It also serves as the

negative lead for resistance testing.

To test the auxiliary ground lead, contact the probe tip and the

auxiliary ground lead together. The Green LED on the display

should light. This shows that the auxiliary ground lead is work-

ing properly.

If the green LED does not illuminate, check the replaceable

20 amp fuse (5x20mm fast blow) in the auxiliary ground lead.

The fuse is a protection in the event the lead is inadvertently

contacted with battery positive.

e) Flashlight

Flashlight is a standard feature on the Hook. The bright LED

Flashlight is always ON making it possible to probe under

dashboards and in dark areas.

f) Sleep Mode

The Hook will go to sleep after 10 minutes of inactivity and you

will see the word SLEEPING on the display. The Flashlight

and the LCD backlight will turn off. To wake it up, just press

any button or contact the probe tip to a circuit.

a) Voltage Testing in Power Probe

Hook Mode:

Voltage testing is as easy as contacting the probe tip to a

circuit and reading the display. There is no need to select the

voltmeter before probing because the Hook does that automat-

ically. The Hook also provides both the battery source voltage

and the probe tip voltage on the display screen for easy volt-

age comparing.

To test for voltage in Power Probe Hook Mode:

1. Take note of the preference parameters in the display.

2. Contact the probe tip to a voltage potential.

3. Take note of the difference between VOLT and BATT on

the display.

If the voltage difference is within the LED Voltage Drop Prefer-

ences, the Red LED will light and the HOT SHOT®symbol will

be present.

If the voltage difference is greater than the LED Voltage Drop

Preferences, the LED will not light.

4. Voltage is measured from 0 to 99.9 volts.

IV - POWER PROBE HOOK MODE

In Power Probe Hook Mode the “Smart Tip Advantage” gives you several new powerful tools to

help you x electrical problems faster than any other circuit tester in its class. Why?

Because it automatically selects the:

RIGHT METER and the RIGHT FUNCTION for the RIGHT CIRCUIT condition.

b) Resistance Testing in Power Probe

Hook Mode:

Resistance testing is as easy as contacting the probe tip to

a circuit or a component and reading the display. There is no

need to select the Ohm Meter before probing because the

Hook does that automatically. It will also auto-range the deci-

mal point.

To test for resistance in Power Probe Hook Mode:

1. Contact the probe tip to a circuit or component with

resistance to ground. Resistance is measured and

displayed from 0 to 15 mega ohms. When Resistance is

less than 1 Ohm the Green LED will be on.

It is necessary to connect the ground lead to a chassis or other

common ground point to accurately measure 2 Ohms or less.

This will eliminate voltage drops within the 20 ft cable and

improve the accuracy.

When testing resis-

tance on some chassis

grounds even though

the ignition is turned

off, you may experi-

ence a millivolt potential

present. When that

happens, The Hook will

display a Dual Meter.

c) Activating Components, Current Draw

Testing and Calculated Resistance in

Power Probe Hook Mode:

Activating Electrical Components in Power Probe Hook Mode

is one of the main features that make the Hook very useful. The

Power Switch (+) and (–) behave differently according to the

Switch Preferences. Notice the Power Switch Settings on the

preference line (see section III-a), for Power Switch Behaviors

(see section III-d).

On 12 volt systems the incidence of arcing is low for ease of

operation. Arc Detect has been disabled in all modes. Arc de-

tect is functional in Power Probe mode only when the source

voltage exceeds 16V. Arc detect can interfere with the function

of some devices. When using the HOOK on vehicles with 24V

and above source voltage. It may be necessary to use Power

Plus mode when the devices you are powering are electrically

very noisy as on some motors or horns. Use caution and follow

instructions on how to properly power up a circuit. Because of

the danger present with higher voltages to the vehicle and you,

it is recommended to use Power Plus mode for powering up in

these higher voltage systems when possible.

Current Draw Testing and Calculated Resistance are dy-

namic tests that are performed by activating circuits or electrical

components with the vehicle’s battery power through the Hook

and measuring the Amps and Ohms. Since the measurements

are made while under power you are getting a true indication as

to its real operating integrity.

To test the current draw and calculated resistance of an

electrical component in Power Probe Hook Mode:

1. Contact the probe tip to the positive terminal of an electric

component that is properly grounded.

2. Press and hold (+). The Hook supplies power to activate it.

During activation the Hook displays the AMMETER and OHM

METER simultaneously.

3. Read the Current Draw displayed as AMP on the screen.

4. Read the Calculated Resistance displayed as OHM on the

screen.

5. If the display shows CIR BREAKR TRIP when you attempt

to activate the electrical component, you will need to

increase the trip point by adjusting it in the Circuit Breaker

preferences. (See section: III-c)

NOTE: The same measurments also can be taken on a battery

(+) referenced circuits by pressing the (-) button.

e) Dual Meter Feature:

The Dual Meter feature is available only in Power Probe HOOK

Mode. When diagnosing chassis grounds it is possible to have

voltage drops caused by systems within the vehicle operating

when the key is off. It can take several minutes for the systems

to shut down. If you are turning the key on and off for diagnosing

purposes, it can be difcult to get accurate resistance readings

due to the voltage drops. Typically ohmmeters will give you a

reading that is skewed by these voltage drops and if you are

unaware they are there, you could spend time xing problems

that don’t exist.

If there are millivolts present on a chassis ground the Power

Probe HOOK will display a unique feature we call Dual Meter.

You will get a resistance reading on the bottom of the screen

and a millivolt reading on the top of the screen at the same

time. The ohm reading displayed when this feature is active will

have a coarse correction factor intended to improve accuracy.

In Power Probe HOOK mode, this feature will automatically

display when the voltage on ground is between .002 and .200

millivolts and ohms is less than 250. If the voltage drops below

.002 volts, normal ohmmeter will display. If there is between

.002 and .200 volts present and the ohms exceed 250, normal

ohmmeter will display. Above 250 ohms, millivolts will have no

affect on the ohm reading. If the voltage exceeds .200 volts,

AP 0

d) Hot Shot®Testing in Power Probe

Hook Mode:

Hot Shot®is available at all source voltages from 12 to 48. The

rule of thumb is that when the Hot shot feature is available,

you can verify the resistance of that circuit is > or < 1 ohm. If

you get a pass result you know the resistance is < 1 ohm and

you have a good power feed connection. A fail result indicates

>1 ohm. For reference, the source voltage does affect the out-

come of the pass result. All pass results reect less than 1

ohm but there is a value difference depending on the source

voltage. Pass at 12V = <.2 ohms, 24V = <.4 ohms, 36V = <.6

ohms, 48V = <.8 ohms. All are less than 1 ohm, but under-

standing this may help in your diagnosis.

WARNING: HOT SHOT®is only designed for supply powers

and grounds. HOT SHOT®should never be used on any sensi-

tive electronics such as modules, sensors etc.

NEVER: Perform any tests on any SRS system without the

system being completely disabled, modules unplugged and

simulators installed in place of all pyrotechnics. Doing so can

lead to injury do to unwanted deployment and permanent mod-

ule damage.

WARNING: When working on computer grounds or any oth-

er sensitive circuits, HOT SHOT®should not be used. The

components need to be unplugged (modules, relays, sensors,

switches, etc.) Now HOT SHOT®can be used to load the wiring

not the component. This is the true method that HOT SHOT®is

intended for, the wiring not the components.

The Hook has a built in two channel Continuity Tester for testing relays and electrical switches. You will also be apply-

ing power to the relay coil using the auxiliary ground lead and the probe tip.

When the 3 wire continuity plug is inserted into the jack, the Red/Green LED’s are now dedicated to the Continuity

Tester. You can still use the Hook normally to power up or read voltage, ohms or amps.

To test a 5 terminal relay in Power Probe Hook Mode:

1. Pull the Rubber Cover from the Continuity Jack and

swivel it out of the way.

2. Insert the 3 Wire Continuity Plug into the Continuity Jack.

3. Connect the Black lead to relay terminal #30.

4. Connect the Green lead to relay terminal #87a. (the Green

LED should light)

5. Connect the Red lead to relay terminal #87.

6. Connect the Hook Auxiliary Ground Lead to terminal #86

7. Contact the Hook Probe Tip to terminal #85.

8. Press (+). (the Red LED should light and the Green LED

should go off)

9. Release (+). (the Red LED should turn off and the Green

LED should light)

normal voltmeter will automatically kick in. With Dual Meter feature, you can better diagnose grounds in the presence

of voltage drops without having to waste time waiting for the systems to shut down! Now that’s a Smart Tip Advantage!

Interpreting the data: The intention of this data is to inform you that accurate resistance measurements cannot take place

when millivolts are present. Standard ohmmeter readings will provide completely unusable data under this condition.

Is your high resistance reading due to a poor connection or a voltage drop? The Power Probe HOOK is the rst in the industry to

answer this question in one simple test. With the Dual Meter feature you are now alerted to the voltage drop while conducting a

resistance test. The HOOK will supply you a more accurate resistance reading during this scenario. The fact remains that if you

see a voltage drop during the resistance test, you will need to remove the voltage drop to acquire the most accurate resistance

reading, however, now you can continue testing using the Dual Meter with the voltage drop present and the resistance value

as a guide since The HOOK is displaying a more accurate reading under this condition.

Note: Due to voltage drops inherent in the 20 foot power cable the ohm meter may experience some error below .30 ohms

depending on the distance from battery to your measurement.

(a) Arc Detect

On 12 volt systems, the incidence of arcing is low therefore, for ease of operation the Arc Detect has been disabled in all

modes. Arc detect is functional in Power Probe mode only when the source voltage exceeds 16V. Arc detect can interfere

with the function of some devices. When using the HOOK on vehicles with 24V and above source voltage, it may be neces-

sary to use Power Plus mode if the device you are powering are electrically very noisy as on some motors or horns. Use

caution and follow instructions on how to properly power up a circuit. Because of the danger present with higher voltages

to the vehicle and you, it is recommended to use Power Probe mode for powering up in these higher voltage systems when

VI - POWER PLUS MODE

ARC DETECT IS DISABLED! Use CAUTION

This is an active mode used for activating electrical components similar to Power Probe Hook Mode except the Arc Detect

feature is disabled. The Power Switch and Circuit Breaker Preferences apply here in Power Plus Mode as they do in

Power Probe Hook Mode. Power Plus Mode will measure and display the Min/Max Current draw so you capture in rush

and stabilized current. High current can be an indication of a sticking or dragging motor or pump.

To access Power Plus Mode from Power Probe Hook Mode:

1. Press SEL once.

2. Press U once

3. Press SEL.

4. You should see AMP in the display.

To activate an electrical component in Power Plus Mode:

1. If the electrical component is already grounded in the

vehicle, you can skip step 2.

2. Connect the auxiliary ground lead to the ground of the

electrical component.

3. Contact the probe tip to the positive terminal of the

component.

4. Press (+). The component should activate.

5. Read the display for the average current draw along with

the Min/Max measurements.

6. To reset the Min/Max Press R

VII - VOLT METER MODE

The Volt Meter Mode is a passive mode. The (+) Power and (–)

Power buttons are not active so dynamic circuit testing cannot

be performed. This means, no Power will be activated to the

probe tip even when you press the Power buttons.

Volt Meter Mode monitors the probe tip and displays 3 voltage

measurements, Average, Min. and Max.

Min/Max can be reset by pressing the R button.

To access Volt Meter Mode from Power Probe Hook Mode:

1. Press SEL once.

2. Press D, 4 times.

3. Press SEL once.

4. Connect the probe tip to the circuit you want to

monitor and test.

5. Press R to reset the Min/Max

VIII - OHM METER MODE

Ohm Meter Mode monitors the probe tip and displays 3 resis-

tance measurements, Active, Min. and Max. The Ohm Meter

Mode is a passive mode. This means no Power will be activat-

ed to the probe tip even when you press the Power buttons.

To access Ohm Meter Mode from Power Probe Hook Mode:

1. Press SEL once.

2. Press D, 5 times.

3. Press SEL once.

4. Connect the probe tip to the circuit you want to monitor

and test.

5. Press R to reset the Min/Max.

This mode can only display ohms. In order for Ohm Meter

Mode to operate there must be no voltage on the circuit. If the

probe tip comes in contact with voltage the Over Voltage alert

will sound.

It is necessary to connect the ground lead to a chassis or other

common ground point to accurately measure 2 Ohms or less.

This will eliminate voltage drops within the 20 ft cable and

improve the accuracy.

APPLICATION: If you have a wire bundle and suspect the

wiring may have a short or open, you can connect the tip to

the circuit and check that the resistance is within the expected

limits. If it is, reset the Min/Max by pressing the R button, then

move or wiggle the wire bundle. If a wire has an intermittent

open, you will see a sudden change in the Max reading. Its

exact reading may not be of value as much as the change in

reading. If there is a sudden short in the wire, it will be cap-

tured on the Min reading. Again, it is the sudden change more

than the actual reading that tells you there is a problem with

that wire.

Once you have captured Min/Max data, the data will remain on

the display until a new Min/Max either overrides it or until you

press the R button, which will reset the Min/Max to Average.

Ohms Min/Max is a feature of the Ohm Meter Mode only. It is

not available in Power Probe Hook Mode. To return to Power

Probe Hook Mode, press SEL button once or press the L but-

ton to return to the menu. To return back to Ohm Meter Mode,

follow steps described previously.

IX - Injector Mode

Injector Mode serves two purposes.

First the ability to test the fuel injector driver and second to test

the injector circuit itself.

First, unlike standard Noid lights that require you to discon-

nect the injector harness, The HOOK can be back probed into

the fuel injectors control circuits at any location. Once con-

nected, select the Injector Mode. Now if you have a no start,

crank the vehicle and you will see the LEDs ash and hear the

speaker at the same rate the driver is controlling the injector.

Many vehicles today need to have the injector connected for

the driver to function and are impossible to access. A standard

Noid light will not work as a tester because of these limitations.

The ashing LED’s and audio monitoring of the injector driver

are designed for cranking and lower rpm’s.

Second, the display will indicate the inductive kick voltage of

the injector circuit. This is a direct result of the strength of the

injector coil. When comparing all of the injector inductive kick

voltages, the weak coil or circuit with high resistance will stand

out. Think of this as the quickest injector circuit tester on the

planet, scope like data without the scope.

When the inductive kick voltage exceeds 35V, both red and

green LED’s will ash simultaneously at the rate the injector is

ring based on cranking or idle speed letting you know it is op-

erating. This is not to be confused with a Noid light. If you see

voltage dropping below an expected level or an unexpected

disruption in the audible and visual indicators, you will have the

information as to the condition of that injector or circuit.

Let’s understand how to use this data. No ashing LED’s and

no speaker tone can mean the driver is not working or an open

circuit. LED’s ashing/speaker tone means that at least 35

volts has been measured in the inductive kick. This means the

injector driver is working. Now we can pay attention to the ac-

tual voltage reading. Normal inductive kick voltages vary from

manufacturer to manufacturer. With that said, you can expect

a range from approximately 50 to 80 volts. The important point

here is to compare all the voltage readings from the vehicle’s

injectors. The one that is different from the rest will be revealed.

The lower voltage indicates a weak injector coil or high resis-

tance in the circuit. When cranking the engine it may be neces-

NOTES: Counter mode including pulse width and duty cycle

is not intended for use on fuel injectors. Injector mode will not

provide any usable data on the 12volt supply to the injector. It

is designed to read the fast rapid rise of the inductive kick only.

APPLICATION: This can be useful when checking the wiring to

an ECM/ECU. After you have checked out your sensor using

the voltmeter and or ohmmeter, if there is still a problem, you

can simulate the voltages that are put out by sensors in order

to verify the wiring going to the ECM/ECU. Using an OBD scan-

ner you can verify the results out of the ECM/ECU. You can

select voltages from 0 to 5 VDC in .5-volt increments (Default

is 0 volts)

The actual voltage on the tip will be displayed on the top of the

screen and the set point voltage displayed on the bottom. There

is a Set Point Voltage Alarm in case the circuit connected to the

probe tip forces the voltage above or below the set point voltage

by .1 volts. This is separate from the Over Voltage Alarm that

trips at >99.9 Volts. The Set Point Voltage alarm will emit a short

tone and you will notice the difference from the actual voltage at

Safety Information: ALWAYS USE SAFETY GLASSES, OR EYE PROTECTION.

There are a number of safety features built in to the Power Probe Hook to protect the tool, the test circuit and you! Below

is a list and brief description of all the safety features.

1. Circuit Breaker:

Shuts off current to the tip if set value is exceeded. Plays tone specic to Circuit Breaker trip. In momentary you must

re-energize the Power Up buttons, in Latch Mode and Pulse Mode, power re-energizes automatically. Only available in

Power Probe Hook Mode (HookM) and Power Plus Mode.

2. Thermal Overload Trip feature

Powering up loads generates heat within a circuit depending upon the load and the duration. The Power Probe Hook has

built in calculated thermal protection. This means the higher the load and longer the duration, the higher the Power Probe

Hook will assume its internal temperature. The Power Probe Hook can drive a 25 amp load continuously but can only

drive a 65 amp load for about 8 seconds. If the thermal overload is tripped, the power will be terminated and the thermal

overload warning, “OVER TEMP” will appear on the display with a count down bar that will countdown for 10 seconds. You

will hear a tone specic to Thermal Overload. If the load is immediately repowered again after the Thermal Overload, the

run time will continue to shorten before Thermal Overload triggers again.

3. Overvoltage Alarm

If the voltage on the tip exceeds 99.9 Volts AC or DC the display will read Overvoltage and you will hear a specic tone.

The Hook has been rated for + or - 500VDC maximum to protect the tool. Available in all modes.

4. Sleep Mode

Sleep Mode is designed to preserve the life of your Display Back Light. Sleep Mode only works in Power Probe Hook

Mode when not being used. If you leave your meter in any other mode the Hook will stay active. The life of the Backlight

is 10,000 hours. Leaving the Hook Powered Up in any mode other than Power Probe Hook Mode will subtract from the

overall life and is not recommended. If you have powered up the Hook and it is sitting in Power Probe Hook Mode with no

action being taken for 10 minutes, your Hook will enter into Sleep Mode. At this time the Flashlight and Backlight will be

turned off and SLEEPING will appear on the display. If the tip senses a change or any button is pressed, the Hook will

wake up. It is ok to press any button when in sleep mode to wake it up. If a button is pressed when asleep no action will

be taken for the button pressed at that time only. The next press will be active. Available only in Power Probe Hook Mode.

5. Set Point Voltage Alarm

In Voltage Reference Mode only, if the voltage on the tip is different from the set voltage, a tone will sound.

6. Reverse Polarity Hook Up

The Hook has built in protection against reversing the polarity of the Hook Up Clips.

7. Fuse protection

The Power Probe Hook Up Clip set has built in fuse protection. Never try to connect your Power Probe Hook to a battery

without the proper supplied connector. Fire can occur! If the Hook Up Clip set is in proper working order, a light can be

seen glowing within the side of the connector body. If your Power Probe Hook is not powering up, check to see that the

light is lit. If not and the polarity is correct, you need to replace your Hook Up Clip set and have your Power Probe Hook

inspected for possible damage before using again.

The Ground Cable also has a fuse protection in the event that the Ground Cable comes in contact with a positive battery

source or it exceeds 25 amps continuous when using the Ground Cable as ground source. It has a replaceable 20mm

x 5.5 mm automotive fuse. To replace fuse, pry out fuse cover from Ground Cable connector body, remove old fuse and

insert new. Press back into Ground Cable connector body.

• Don’t forget to warranty your product by going to www.powerprobe.com/warranty/ or ll out & mail in the warranty card.

• Power Probe Hook Mode is Auto Selecting and Auto Ranging. This means you don’t have to gure out which button to

press to get Volts or Ohms and Amps will display when you press the power button.

• Take the time to get very familiar with the preference line of the Hook. (See section III-a)

The symbols at the top of the display after boot up are the default preference values. If you change the preference values,

the values at the top will change accordingly. This way you always know how your Hook will operate.

• Battery voltage will always be displayed on the lower line in Power Probe Hook Mode when the tip is unloaded. The rst

thing you must do after power up is look at the battery voltage and decide if it is within operational voltage of the Hook,

9-48 VDC. If the Hook doesn’t power up, check your battery rst, then make sure your battery clips are on the correct

polarity and the LED in the battery clips is lit.

• The menu system is like a corridor. When you rst power up, you will be put into the room Power Probe Hook Mode.

You can enter into to the corridor by pressing the SELECT button. You can move up and down the corridor using the UP

or DOWN ARROW buttons to reach different doors. You can enter any room along the way by using the RIGHT ARROW

button. You can exit these other rooms by pressing SELECT or the LEFT ARROW button.

• All preferences will return to default on the next power up unless you use the Save Preferences function. If you like

where you have set your preferences and want to save them, use the Save Preferences Option. (see section XII)

• If you don’t like your saved settings, use Default reset to restore factory settings. (see section XII)

• Min/ Max are NOT found in Power Probe Hook Mode. It is only found in Volt Meter, Ohm Meter and Power Plus Modes.

• There is an Arc Detect function that is designed to preserve your tip and circuit. It is active in Power Probe Hook Mode

but is not in Power Plus Mode.

• Components that depend on arcs such as horns and motors can be affected by the Arc Detect circuit. Most horns and

motors should not be affected but depending on the component and its age, there may be interference caused by Arc

Detect. If you intend to power up something like a motor or horn you can go directly to Power Plus Mode and apply full

power. Caution must be used on high current devices. Always use the Power Probe Hook safely as described in the

manual.

• The larger the current draw the less run time before Thermal Overload Protection is activated. It is not a sign of com-

ponent failure. The Hook is protecting itself. The longer the cool down time the longer the subsequent run time and vise

versa. Thermal overload will shut down power for 10 seconds if triggered. The Hook can run 25 amps continuously.

• There are 4 types of meters in Counter Mode including a simple pulse counter, positive and negative pulse widths and

duty cycle. All but pulse counter display frequency with the selected meter.

• There can be AC signals in DC systems. If you want to measure them, lower your AC threshold setting to the lowest set-

ting to display a peak to peak voltage when an AC voltage greater than that setting becomes present on the tip. Increase

the sensitivity to only detect higher levels of AC voltage when present. AC Peak to Peak will override Volt Meter when in

Power Probe Hook Mode. Set the AC Threshold preference to the highest setting if you nd that unimportant AC signals

are interfering with your DC voltage readings.

• This device is NOT intended for AC voltage measurements other than those in DC systems from 12-48VDC.

AC Peak to Peak and Frequency are the same function.

• The speaker can only be turned on and off in Power Probe Hook Mode.

• The Red and Green LED’s will not detect Voltage Drop unless in Power Probe Hook Mode.

• You may have to adjust your Voltage Drop preferences to get the Red/ Green LED’s to work as a Voltage Drop Meter.

• When the 3 wire continuity plug is inserted into the jack, the Red/Green LED’s are now dedicated to the Continuity Tes-

ter. They will respond to either the red or green wire respectively when touched to the black. You can still use the Hook

normally to power up or read voltage, ohms or amps.

• The auxiliary ground has a replaceable 25 amp fuse. Always touch it to the tip for continuity before using it to make sure

the fuse is not blown.
