    (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.
  • Page 5: Safety

    • 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.

    7. DRV TST – Supplies safe voltage for testing computer driver circuits. 8. PPECT – Detects the open circuit signal from Power Probe ECT2000 to assist in locating opens. Refer to sections: Testing and Measuring Operations and Advanced Testing Operations for further mode descriptions and suggested applications.

    LED will illuminate and the speaker will make a low-tone. This greatly simplifies testing as the Power Probe IV’s Red/Green LEDs and speaker tones provide a quick indication if there are excessive voltage drops or circuit resistance. If the LEDs do not illumi- nate and there is no tone from the speaker, you know instantly there may be a circuit problem.
  • Page 11: Activating Components

    Activating Electrical Components in VDC Mode is one of the main features that make the Power Probe IV very useful when testing. Being able to ap- ply battery power or ground right to the probe tip gives you the ability to activate and dynamically test electrical components such as lights, motors, and solenoids.
  • Page 12 PFT can also be used like a standard ohmmeter. PFT displays both Battery and Tip voltage simultaneously for easy voltage drop testing. In this mode, the Power Probe IV display will show: - Total circuit Resistance on the center screen. - Probe Tip Voltage.
  • Page 13 Power Probe IV Page 1 1 Testing and Measuring Operations Power Feed Testing To test, first disconnect the device or load being operated from the circuit, then contact the probe tip to the circuit being tested. Removing the component from the circuit prevents the component load from affecting and altering the resistance reading.
  • Page 14: Ac Voltage Measurement (Rms)

    The Power Probe IV can safely measure up to 70 VAC. WARNING Do not use the Power Probe IV to test AC line voltage, such as a 120V wall plug. Attempting to use the Power Probe IV on AC line voltage will damage the probe and could cause personal injury.
  • Page 15: Ac Voltage Measurement (P To P)

    For example, if you have an AC signal that alternates from -50V to +50V the Power Probe IV will display a P-P voltage of 100V, a Min voltage of -50V and a Max voltage of +50V.
  • Page 16: Frequency Measurement

    – Pulse Width and + Pulse Width in milliseconds on the bottom line. The Power Probe IV can measure frequencies from 1Hz to 9999Hz. FRQ CTR can be used for tests where frequency or pulse width are needed such as MAF sensors, wheel sensors, etc.

    ECT Receiv- er alone. When you select the ECT Mode, the Power Probe IV is now specifically tuned to detect the ECT open circuit signal. The Power Probe IV is meant to work by direct contact to the circuit.
  • Page 18: Fuel Injector Mode

    FUEL INJ = Fuel Injector Mode is specifically set-up for fast and easy injector circuit diagnosis. One quick connection to the circuit and the Power Probe IV will display all the needed fuel injector testing information that would normally require using an lab-scope.
  • Page 19 Power Probe IV Page 17 Advanced Testing Operations Fuel Injector Mode • Select FUEL INJ from the Power Probe IV’s test menu. • Back-probe on the negative side of the injector, either at the injector or at the PCM. • These four data points represent the corresponding waveform points.
  • Page 20 When the Power Probe IV is in Driver Test Mode, it will provide the necessary voltage and pull-up resistance to ensure proper driver testing.

    Power Probe IV Page 19 Advanced Testing Operations Driver Testing Driver Testing Explained: Suppose you had a shorted solenoid that was not working. You know the solenoid will have to be replaced, but you don’t yet know if the driver circuit was damaged and you may need to also re- place the module.
