- WIDE APPLICATION - ANCEL PB100 circuit tester is a fast and efficient electrical scanning probe, works on all 12-24V vehicle electrical systems, including cars, boats, trailers, fuel pumps, relays, and more.
- A MUST-HAVE TOOL - Designed for voltage & polarity testing, continuity testing, signal circuit testing, supply power/activating components, trailer lights & connections testing. It features red/green polarity indicators, follows & locates short circuits, and checks bad Ground contacts.
- 4 WORKING MODES - DC Voltage mode for reading the DC voltage with a resolution of 0.1 volts; AC Voltage mode for reading the Max. voltage, the Min. voltage, and frequency; Resistance mode for reading the resistance between the tip and auxiliary ground lead; Diode mode for checking forward bias or reverse bias.
- SAFETY & DURABLE - An auto circuit breaker makes this tool very safe and sustainable and its short-circuit protection protects the device from overload. A quick self-test is a must before starting to test a circuit or component, which ensures your tool is in excellent condition.
- FRIENDLY DESIGN - A friendly navigate user menu makes it easier to operate, even a beginner without a manual. Built-in 2 headlights allow you to work in the dark area; an extra 20 feet extension cord allows reaching wires in or out of the vehicle or some congested places; a rugged carry case to store the tool whenever.
