This Clamp Meter is designed to Safely.Accurately and Fast troubleshoot a variety of automotive and household eletrical problems. With a wide range of test functions and features, it is a true clamp multimeter.

Ultra-portable tools for advance electricians. The DC AC current can be tested quickly, accurately and safely without damaging the insulation on the line surface.

Product Advantages:

● Ultra-portable tools for advance electricians, Has True RMS characteristic,The test results are more realistic.

● DC/AC Current Range 0~100A (1 mA Resolution), DCμA Feature: 0~200μA, (1μA Accuracy).

● Max display value: 6000 Counts, Compared with similar products,The ACM91 still has 1mA accuracy (0~6A) for a larger measurement range.

● Has Zero Clear Function and Data hold, Apply to the test to make the test more accurate.

● Can meet the test requirements of different scenarios. It is a true clamp multimeter.

● In the function of the traditional clamp meter, increase DC microampere, Temperature, LoZ low impedance test, Dangerous voltage alarm(NCV), Live/Neutral wire distinguish function.

● Has Dual impedance voltage test mode (Traditional measurement and low impedance measurement), The voltage test is more precise and can meet the needs of professionals.

● Dangerous voltage alarm function, Sound / Red light at the same time reminder, more intuitive.

● Feature-rich: Has DC/AC voltage, DC/AC current, DC microampere, Resistance, Capacitance, Frequency, Temperature, LoZ low-impedance test , Continuity, Dangerous voltage alarm (v~alert/NCV) and live/neutral wire distinguish function. with such a small size it meets the rules of the state has made the most perfect functions.

● Support one-handed switching of all test functions(complete in 1.5 seconds), making operation more convenient and quick.

● LIVE wire check function and V ~ alert function conveniently quickly identify mains connection status.

● Can display voltage or current and frequency at the same time.Quick and easy to complete testing.

● There are three colors, Blue, Black and Gray. There is always one that you like.

● Streamlined design for more comfortable operation; LCD display(1.72 inches) with backlight for clear reading.

● Has Data hold, Low battery indication functions, Auto power off features, Added back hooks.

● Jaw opening size 20 mm;The body size of the product is -17.5CM*5.5CM*3.5CM, which is more convenient to use and carry.
