AstroAI Digital Clamp Meter Multimeter 4000 Counts Auto-ranging Amp Tester Measuring AC DC Voltage & Current, Resistance, Capacitance, Frequency, Continuity, Live Wire Test, NCV Detection

Brand	AstroAI
Power Source	Battery Powered
Style	4000 Counts AC/DC Current
Color	Red
Item Weight	410 Grams

Versatile Digital Clamp Meter: Accurately measures AC/DC Current, AC/DC Voltage, Capacitance, Frequency, Duty Cycle, Resistance, Diode, Continuity and Live Wire Tests. This clamp meter is a really useful tool for solving industrial and household electrical issues.
Non-contact Voltage Testing: This Clamp Meter features non-contact voltage testing with sound and light alarms. When the Meter senses a weak AC signal, the green indicator light will come on and the buzzer will emit a slow, audible beep. when the Meter senses a strong AC signal, the red indicator light will come on and the buzzer will emit a brief beep
Multifunctional & Easy to read: Support Data Hold, Max/Min, Auto power off after 15 minutes inactivity, low battery indicator and continuity buzzer. The LCD Backlit Screen and Flashlight make it easy to use in a dark working area. ZERO function decreases the data error influenced by the Earth’s magnetic field, and helps you to obtain a more accurate measurement.
Large Jaw Opening: The jaw opening measures current in a conductor without touching or interrupting the circuit. Its slim and compact size makes it easy to operate in narrow spaces.
Additional Tips: This clamp meter has passed the environmental pollution test degree 2 and overvoltage category III 600V safety standards.

Product Description

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.

AstroAI 4000 Counts TRMS Clamp Meter

The AstroAI True RMS 4000 Counts Digital CLAMP METER is designed to be safely and accurately used by professionals and weekend DIYer’ s. It is suitable for commercial and household electrical problems. Advanced features have been provided including AC/DC Voltage, AC/DC Current, Frequency, Duty Cycle, Resistance, Capacitance Measurement and NCV Detection, Flashlight, Diode, Live Wire Test and Audible Continuity Testing.


Test AC/DC Voltage, AC/DC Current, Resistance, Capacitance etc. The CM4KOR Clamp Meter can accurately measure AC/DC Voltage, AC/DC Current, Resistance, Capacitance etc.	Frequency and Duty Cycle Test Turn the rotary dial to the “Hz/%” setting (Duty Cycle Test: Please press the FUNC button to duty cycle test.) 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.


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.
