Power Probe PP3EZ Automotive Circuit Tester 12V 24V – Voltmeter, Polarity Tester, Continuity Checker & Component Activator with EZ Diagnostics, EZ Learning, 180° Flip Screen, 8A Breaker (Green) POWTK3EZGNCS
DIAGNOSE 12V & 24V ELECTRICAL FAULTS IN SECONDS – Identify voltage level and polarity at a glance with a single probe tip; no need for a separate voltmeter, no jumper leads and no second hand. Press the rocker switch forward to apply battery POWER, or pull it back to apply GROUND directly to any component for instant functional testing on cars, vans, motorcycles, trailers, marine, RVs and 24V commercial vehicles. EZ DIAGNOSTICS – GUIDED VEHICLE TESTS BUILT-IN – The PP3EZ is the only Power Probe with on-screen guided test routines for Battery Check, Charge Test, Fuse Test, Voltage Test, Component Test and 5V Reference (with optional PPT5VA adapter). The tool walks you step-by-step through each procedure and tells you whether the readings are within spec — perfect for apprentices and time-pressed pros alike. EZ LEARNING MODE & 180° FLIP SCREEN – Built-in interactive EZ Learning teaches you exactly how the probe responds in each test condition, so you build confidence faster on real jobs. The 180° rotating LCD lets you read voltage upside down when probing under the dash, behind panels or above the engine bay — no more contorting your neck or fumbling with mirrors. 5 ADVANCED MEASUREMENT MODES FOR DEEPER DIAGNOSIS – DC Voltmeter (0–70V), Peak-to-Peak (4Hz to >500kHz square / >250kHz sine), Max Peak, Min Peak and AC Threshold capture pulses as short as 1ms — ideal for testing fuel injectors, ignition coils, crank/cam sensors, oxygen sensors, hall effect sensors and any pulsed DC signal. Two-level continuity check (LCD <20kΩ, green LED 70V) and over-load (>34Vdc) warnings. Includes a 20ft (6m) power cable for bumper-to-bumper reach. CAT II/III/IV unsafe – designed for 12–24V automotive use only., Weight: 1.6 pounds, Manufacturer: Power Probe
