Introduction

Power Probe IV

Thank you for purchasing the Power Probe IV Diagnostic Electronic Circuit and Component tester. The Power Probe IV is the next generation of Power Probe Circuit Testers. Now loaded with powerful multimeter functions, advanced diagnostic test modes, an easy to read color LCD display and a new rugged water and dust resistant housing, the Power Probe IV is designed to give you years of trouble free testing, even in the most demanding work environments.

The unique conﬁ guration of Power Probe testers gives them many advantages over using conventional test lights or multimeters for circuit testing.

(1) Since the Power Probe IV is connected to the battery, you can apply battery power or battery ground directly to the tip of the tool. You can energize and activate components to verify their correct operation. This is real dynamic component testing and the only true way to test an active component.

(2) The Power Probe IV is always connected to the vehicle’s battery, so the tool maintains a permanent connection to the source power and ground voltage. Circuit voltage checks are quickly performed with just a single probe connection, unlike using two meter leads.

(3)Using the PPIV, all your voltage checks are referenced back to the source battery and account for every connection and possible voltage drop between the source and the probe tip.

(4) Automatic Voltage Drop Indication When probing a circuit, if the voltage measured at the tip is 0.5 volts lower (or more) than the source battery voltage, the red LED will not Illuminate and no speaker tone will sound. This will instantly alert you that there is a voltage drop that may need to be investigated or repaired.

Safety

CAUTION - PLEASE READ

To avoid possible electric shock or personal injury and to avoid damage to the Power Probe or item being tested, please use the Power Probe according to the following safety procedures:

• Power Probe recommends reading this manual before using the Power Probe IV.

• This product is designed to be powered from DC power sources such as found in Automotive, Small Craft Marine and Small Craft Aviation electrical systems and will be damaged if connected to line voltage such as 115V AC power sources or 24V AC Control circuits.

• Do not connect to electrical system with higher than rated voltage speciﬁed in this manual.

• Do not test voltage exceeding the rated voltage on the Power Probe IV.

• When testing voltage exceeding 30V AC RMS, 42V AC Peak, or 60V DC, be particularly careful to avoid any electric shock.

• Check the Probe IV case for cracks or damage. Damage to the case can leak high voltage causing a potential electrocution risk.

• Check the Probe IV cables for any insulation damage or bare wires. If damaged, do not use the tool, please contact Power Probe Technical support.

• Use only shrouded leads and accessories authorized by Power Probe to minimize exposed conductive electrical connections to eliminate shock hazard.

• Do not open the Power Probe IV, no serviceable parts are inside. Opening the Power Probe IV voids the warranty. All repairs should only be performed by authorized Power Probe service centers.

• When maintaining the Power Probe, use only replacement parts speciﬁed by the manufacturer.

• Use only in well ventilated areas. Do not operate around ﬂammable materials, vapor or dust.

• Be careful when energizing components that have moving parts, assemblies containing motors or high powered solenoids.

• Power Probe, Inc. shall not be liable for damage to vehicles or components caused by misuse.

• Power Probe, Inc. shall not be held liable for any harm caused by unintentional or intentional misuse of our products or tools.

• If you have any questions please go to our website www.powerprobe. com or contact Power Probe’s Technical Support: 800-655-3585.

Appearance and Controls

Removable Probe Tip - Uses standard 4mm

banana type connector enabling use of different probes, leads, or extensions.

LED, Green (-) - Will light indicating a path

to ground. More than10Ω resistance and/ or more than 0.5 volts on a ground circuit, the Green LED will not illuminate.

LED, Red (+) - Will light indicating (B+)

Battery positive. If the circuit voltage drop is more than 0.5 volts from battery voltage, the Red LED will not illuminate.

Color Screen - Large Hi-resolution LCD

display shows multiple readings on one screen.

Start-Up

Operating Source Voltage

The Power Probe IV is designed to connect to and is powered by 12 to 24 VDC electrical systems. It comes supplied with a 23 ft., heavy duty power cable and a Y-connector with 2 battery clips.

Connecting to the Vehicle’s Battery (Voltage Source)

Connect the red clip to the positive terminal of the vehicle’s battery source and the black clip to the negative or ground terminal. The Power Probe IV start-up tone will sound.

Auxiliary Ground Lead

The auxiliary ground lead provides ground to circuits and components that are not already 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 should illuminate. This shows that the auxiliary ground lead is working properly. If the green LED does not illuminate, check the replaceable 20 amp fuse in the auxiliary ground lead. The fuse is for protection in the event the ground lead inadvertantly contacts the battery positive.

LED Flashlight

Flashlight is a standard feature on the Power Probe IV. The two bright white LEDs are always ON making it possible to see under dashboards and in dark areas.
