This product is designed for use in monitoring car battery voltage, leakage current, and serving as a backup power supply when replacing the battery. The product is connected to the car's OBDII interface via an OBDII connection cable to supply 12V power to the car and monitor the car system's leakage current for diagnosing various faults. It can also serve as a backup power supply for the car during battery replacement, preventing the car's mainboard from losing power and data. Draw Monitor can also monitor battery voltage through the OBDII port. Please read the instruction manual carefully before using the product.

The Power Probe 4 Master Combo Kit combines the Power Probe 4, ECT3000 and various accessories to provide the ultimate combination of diagnostic and circuit-testing capabilities.

The Power Probe 4 provides simplified testing of Motors, Lights, Relays, and Sensors, and even Fuel Injectors. Also, like all Power Probe circuit-testers, it supplies Power and Ground for functional component testing on or off the vehicle. The ECT3000 will help you trace short and open circuits quickly and accurately.

The Power Probe Maestro is a cutting edge circuit tester designed for professional automotive diagnostics. As part of the Pro Series, it features advanced multimeter functions, diagnostic modes, and an easy-to-read color LCD display housed in a rugged, dust- and water-resistant casing.

With scope-like trace mode, DC and AC voltmeter capabilities, and fuel injector testing, the Maestro simplifies troubleshooting for motors, lights, relays, sensors, wires, and communication circuits. It operates on 12V and 24V systems, offering precise voltage, resistance, and frequency measurements.

Additionally, the Maestro pairs wirelessly with the Power Probe app, enabling remote display, data streaming, and recording for enhanced diagnostics.

The Power Probe PP3EZ includes all the powerful testing modes and features of the Power Probe III plus now includes 2 new modes - EZ Learning Mode and EZ Diagnostics Mode. The PP3EZ speeds you through the diagnosing of 12 to 24 volt automotive electrical systems. After connecting the PP3EZ's clips to the vehicle's battery, the automotive technician can determine at a glance, the voltage level and the polarity of a circuit without running for a voltmeter or reconnecting hook-up clips from one battery pole to the other. The power switch allows the automotive technician to conduct a positive or negative battery current to the tip for activating and testing the function of electrical components without wasting time with jumper leads.
