【Widely Applicable】 The AstroAI 4000 count tester can accurately measure AC/DC voltage up to 600V, current up to 10A, and resistance up to 40MΩ. It can be used for continuity, diode, and voltage testing. It features 1.5V and 9V battery test modes, allowing for easy testing of various batteries.
【Multifunctional】 Supports true RMS, AC/DC current, AC/DC voltage, auto-ranging, continuity check, resistance, diode, capacitance, and live wire measurement. It also features NCV (Non-Contact Voltage Detection) functionality for added safety.
【Convenient】 Compact size for easy portability. Features a rear stand and test lead storage for added convenience. Low battery prompt and data hold button retain readings for easy reading. Automatic power-off after 15 minutes of inactivity. Large backlit LCD screen allows for use even in dimly lit environments. Easily switch between modes to suit various usage scenarios.
【Safety】 Safety is the top priority; the NCV function minimizes exposure to live wires. It works with outlets, sockets, and terminals. It features overload protection and thick protective rubber, making it shock-resistant and effectively preventing damage from drops.
[Live Wire Detection] The red test lead allows you to detect live wires. This unique function tests for the presence of live wires. When a live wire is detected, the digital tester will sound an audible alarm.
