ACM91 Product Description: 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. Has True-RM characteristic, Max display value: 6000 Counts. DC/AC Current Range 0~100A (1mA Resolution), DCuA Feature: 0~200uA, (1uA Resolution). Compared with similar products, The ACM91 still has 1mA accuracy (0~6A) for a larger measurement range. Has Zero Clear Function, DC test is more accurate. Has low impedance voltage test mode. The test results are more accurate. With temperature test function, the use scene is more extensive and convenient. When testing AC Voltage / Current, Simultaneous Display Frequency. Support one-handed switching of all test functions, making operation more convenient and quick. LCD display with backlight for clear reading. Has Data hold, Low battery indication functions, Auto power off features, Added back hooks. With overload protection on all ranges.
