AstroAI Digital Circuit and Voltage Tester with Measurements for True and Diode with Manual and Automatic and Caustic Identification 4000-Count

---------------------------------------------------------------------- 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ---------------------------------------------------------------------- [Widely Applicable] The Astro AI4000 Count Tester accurately measures AC/DC voltage up to 600V, current up to 10A, and resistance up to 40MΩ. It's ideal for continuity, diode, and voltage testing. Its 1.5V and 9V test modes make it easy to test a variety of devices. Multi-function: Supports true RMS, AC/DC current, AC/DC voltage, auto-ranging, continuity, resistance, diode, capacitance, and caustic measurements. Also, the built-in NCV (non-contact voltage detection) function provides added safety. [Convenient] Compact and easy to carry. Features a rear stand and test lead storage on the back for added convenience. The low prompt and data hold button maintain readings for easy reading. Automatic power-off after 15 minutes of inactivity. The large backlit LCD screen allows for easy use even in dimly lit areas. Switch freely to suit various usage scenarios. [Safety] Safety is our number one priority. The NCV function minimizes exposure to live electrical wiring. It works with outlets, sockets, and terminals. It features overload protection and thick protective rubber for impact resistance, effectively preventing damage from drops. [Live Wire Detection] Use the red test lead to detect live wires. This unique feature tests for the presence of live wires. When a live wire is detected, the digital tester will sound an audible alarm.
