AstroAI Digital Clamp Meter Multimeter 4000 Counts Auto-ranging Amp Voltage Tester Measuring AC/DC Voltage & Current, Resistance, Capacitance, Frequency, Continuity, Live Wire Test, NCV Detection
Note: To measure the current you need to clamp the meter around one of the wires and not the whole power cord. The power cord contains two wires carrying the current and ground wires. The current in two wires always flows in opposite directions, so the magnetic fields from two wires cancel each other, therefore the meter reads 0 A. The NCV function can test the voltage without contact. When the Meter senses a weak AC signal, the green indicator light will be on and the buzzer will emit a slow, audible beep. When the Meter senses a strong AC signal, the red indicator light will be on and the buzzer will emit a brief beep. “For All of Life’s Adventures” is more than a slogan for us; it’s a lifestyle and core philosophy.

The screen will display “ HZ/% ” indicating the measurement function. Detects Live Wires Live wire testing with the red test lead. This unique function tests the presence of live wires. When it detects a live wire, the clamp meter will reflect with the audio alarm. Zero Function This function helps decrease the data error influenced by the Earth’s magnetic field, and helps you to obtain a more accurate measurement. Read more NCV Detection This Clamp Meter features non-contact voltage testing with a sound and light alarm. When the indicator light is on, it means there is voltage, please pay attention to your safety. Continuity Test Connect test leads to the circuit, the buzzer inside the Meter will beep if the resistance<50Ω. Correct Measurement Please measure in the correct way, otherwise the readings will not be accurate. Backlit LCD and Flashlight The Backlit LCD and Flashlight ensure clear measurements in a dimly lit area. The Backlight can be switched manually and shuts off automatically after 15 minutes.
