Description: Features: Designed to safely and accurately troubleshoot a variety of automotive and household electrical problems. The multimeter uses 2 pieces 1.5V AAA batteries(not included)as power supply and support auto power off function to save power. Its large 4 digit(4,000)display provides accurate, easy-to-read results that enable you to complete your work quickly and efficiently. Supports continuity testing, resistance testing, diode testing and has better anti-magnetic and anti-interference performance.
