Versatile Digital Clamp Meter: Accurately measures AC Current (DO NOT MEASURE DC CURRENT)! AC/DC Voltage, Capacitance, Resistance, Diode Continuity and Live Wire Tests. This clamp meter is a really useful tool for solving industrial and household electrical issues.
Large Jaw Opening: The jaw opening measures AC current in a conductor without touching or interrupting the circuit. Its slim and compact size makes it easy to operate in narrow spaces.
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.
Additional Tips: The clamp meter has passed the environmental pollution degree 2 and overvoltage category III 600V safety standards. Combined with Amazon's excellent delivery, we provide lifetime....
