About this item

  • 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 of 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. Combined with Amazon's excellent delivery, we provide lifetime technical support.

Product Description

Product Description

1

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..

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.

Things to consider, the DC and AC modes have to be selected with the FUNC button. and the current display has to be zeroed. The product quality is good.

Totally satisfied with the meter. The only downside is that the leads that come with this are really poor quality. The banana plug end of one of leads broke after a days use. Also the wire is not very flexible in cold temperatures. Be prepared to buy new leads in short order. Otherwise the meter body is ok and the amp clamp function is a very good feature. Great for occasional use. If you need a meter daily spend more and buy a Fluke.

Neat little clamp meter. Helped me diagnose a defective meter lead on another unit as well as playing around with the non-contact voltage detector. Robust unit at a fantastic price. Would recommend.

5.0 out of 5 stars Great clamp meter/multimeter
Reviewed in the United States on May 10, 2024
Style: 2000 countsVerified Purchase
This a really nice AC clamp meter + auto-ranging multimeter that's really easy to use, well-built, sold at a very reasonable price. The AC clamp meter is for measuing AC current on single wires. The multimeter functions are pretty standard: VA, VC, Ohm, continuity, etc... with the bonus that it's auto-ranging, and there are only 2 probe ports (other multimeters have 3), so all you have to do is plug in the red probe, the black probe, and the multimeter auto-senses the range and displays the right value. There is no need to guess what port to plug in the probes. The size is compact and slim. 2 wire probes are included. The 2 required AAA alkaline batteries are included in the box, which is a nice touch. There is a protective cordura nylon carrying case with a handle too. You could buy a regular multimeter for about the same price, but this one has a non-contact clamp meter current sensor + non-contact live wire detector + auto-ranging multimeter, and it's easier to use, so it's a no-brainer.
