## Overview

The AstroAI Clamp Meter CM4K0R is a versatile, professional-grade digital multimeter designed for precise AC/DC voltage, current, resistance, capacitance, and frequency measurements. Featuring a large jaw opening for non-intrusive current testing, non-contact voltage detection with audible and visual alerts, and a backlit LCD with flashlight for low-light environments, it meets CAT III 600V safety standards. Its zero function reduces magnetic interference, ensuring accurate readings, making it an essential tool for both industrial and household electrical troubleshooting.

## Description

Product Description AC/DC Voltage, AC/DC Current The CM4KOR Clamp Meter can accurately measure AC/DC Voltage, AC/DC Current, Resistance, Capacitance etc. Frequency and Duty Cycle Turn the rotary dial to the “Hz/%” setting The screen will display “ HZ/% ” indicating the measurement function. Detects Live Wires Live wire testing with the red test lead. 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. 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.

Review: Clamp meter - God value for the money just one point every time it's turned on its in dc mode and then one press of the function button will change it to ac
Review: Not that good - Measured amps but not volts

## Features

- 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.To measure the current you need to clamp the meter around one of the wires instead of the whole power cord.
- Additional Tips: This clamp meter has passed the environmental pollution test degree 2 and overvoltage category III 600V safety standards.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Clamp meter
*by D***. on 12 June 2025*

God value for the money just one point every time it's turned on its in dc mode and then one press of the function button will change it to ac

### ⭐⭐ Not that good
*by M***L on 15 May 2026*

Measured amps but not volts

### ⭐⭐⭐ Hard to find a mult-mimeter that reads DC microamps for under £100, but this one does!
*by D***N on 3 November 2025*

Good value but won't read DC current in less than 100 milliamps so not really suitable for automotive use.
