Main highlights
- 【USER FRIENDLY】With test lead storage, meter leads can be protected and stored when not in use. The LCD backlight screen and flashlight ensure clear readings, even in dimly lit areas. Additionally, the low battery indicator shows the battery status and reminds you to replace it promptly. To save power, the ammeter automatically shuts off after 15 minutes of inactivity
- 【TRUE-RMS AC DC CLAMP METER】This multimeter can accurately measure AC/DC current, AC/DC voltage, temperature (thermocouple included), NCV, capacitance, frequency, resistance, continuity and diode. Good help for troubleshooting the household solar system, automotive and industrial electrical issues, perfect for electricians, DIY, professionals, etc.
- 【NCV DETECTION】Non-contact voltage testing function helps detect AC voltage without direct circuit contact. By simply pressing the button on the right side of the multimeter tester, it is quick and safe to detect electrical status. Also, it is equipped with audible and visual alarms. The stronger the voltage signal, the faster the buzzer
- 【D-SHAPED JAW】Different from other amp meters on the market, the clamp multimeter features a distinctive D-shaped design, and the amp clamp can be opened up to 1.1 inches, providing a convenient and secure way to clamp on various cables
- 【CUSTOMER SERVICE & SAFETY】Passed IEC61010-1 and CAT III 600V certification. The screen turns orange to warn when the voltage >80V, the current >1A. Comes with a nice carry case, manual and two sets of leads for electrical and temp. KAIWEETS provides 36 months of high-quality service and lifetime technical support

Main highlights
- Versatile Digital Clamp Meter - Accurately measures AC/DC Voltage, AC Current, Capacitance, Resistance, Diode Continuity and Live Wire Tests. This clamp meter is a really useful tool for solving industrial and household electrical issues.
- Thoughtful Design - Support Data Hold, Max/Min, Auto Shut-off, low battery indicator and continuity buzzer. Includes Convenient features like Audial and Visual Alarm, LCD Backlit Screen and Flashlight make it easy to use. Two 1.5V AAA batteries are included in the package.
- Non-contact Voltage Testing - This Clamp Meter features non-contact voltage testing with sound and light alarm. 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 quick beep.
- Important Tips - This CM2K0R clamp meter can not test DC Current. To measure the AC Current you need to clamp the meter around one of the wires and not the whole power cord. Ensure the conductor to betested is in the center of the clamp head. The clamp Jaw is only used to measure current. Do not measure voltage by clamping the conductor being measured.
- Enhanced Safety - The clamp meter has passed the environmental pollution degree 2 and overvoltage category III 600V safety standards. If you have any questions about the product, feel free to contact us! Our California-based support team will respond within 24 hours.
