AstroAI

AstroAI Digital Clamp Meter Multimeter 2000 Counts Amp Voltage Tester Auto-ranging with AC/DC Voltage, AC Current, Resistance, Capacitance, Continuity, Live Wire Test, NCV, Blue

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.

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.

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.
