Power Probe 4 PP401AS PP4 / IV 9 Mode Diagonstic Circuit & Component Tester Tool

Features and BenefitsLarge Multi-Line Color LCD Screen (60% larger than the PPIII)Water and dust resistant with loud indicator tonesMeasure DC, AC, and Frequency (HZ)Test resistance on live and unloaded circuitsFuel Injector Tester ModeThe Power Probe IV provides the ability to supply battery ground and power with 9 diagnostic testing modes to provide Automotive Technicians with detailed information on the circuits and signals being tested. The PPIV will test for A/C volts RMS, volts P-P, resistance, hertz, frequency, pulse width (negative and positive), verifies fuel injector driver conditions, supplies computer safe voltage for testing module drivers (transistors), and work as a circuit tracer with the ECT2000 (not included).APPLICATIONS:Test millivolts for parasitic draws, charging system connectors, starting systems, sensors, modules and much moreTest for good source ground and power feedsTest pulse width in fuel injectors and ignition modulesTest frequency (HZ) of regulators, injectors, motors, and sensorsMeasure the resistance of alternators, regulators, switches, solenoids, interlocks, sensor wiring, fuel pumps, and much moreMeasure DC and AC Voltage on diodes, sensors, modules, motors, relays, fuses, actuators, rectifiers, and many more
