Features 1、Comprehensive Functionality: The digital smart multimeter measures AC/DC current, AC/DC voltage, non-contact AC voltage (NCV) detection, live/neutral wire detection, resistance, diodes, capacitance, temperature, and frequency. It provides a wide range of measurements for all your electrical testing needs. 2、Audible Alerts: The transistor testers feature NCV sensors and live/neutral wire detectors that emit audible and visual alerts when AC voltage is detected, ensuring you are always aware of live circuits. 3、Safety and Durability: The ohm diode multimeter tester is equipped with overload protection and 1000V, 10A test leads for safe and reliable use. It features a shockproof and non-slip silicone cover to protect the device from damage and is compact enough to fit in your hand or pocket for easy portability. Additionally, it has an auto-shutdown feature that powers off the device after 15 minutes of inactivity to save battery life.
