This ACM91 clamp meter is and simple-to-use multimeter for household electricity maintenance. It supports measuring voltage, ampere, (by jaw minimum 1 mA), temperature, frequency ,capacitance, DC microampere, resistance, it also supports LIVE wire check and dangerous voltage alert to safer operation. display enables it tp display voltage or current and frequency at the same time. LoZ, low impedance voltage detection makes it perfect for maintenance industry. An tool for equipment testing, maintenance and repairing. Feature - Applicable to industry, power sector, smelting, electronics, manufacturing, petroleum, defence, electricity, chemical and more industries. - For measuring DC and current, temperature, DC and voltage, resistance, frequency and capacitance. - Support diode testing, testing, , continuity testing, maximum and minimum testing, backlight and data hold. - Support and measurements. - Pocket clip design allows for easy storage and carrying. - With digital LCD backlight screen for easy viewing, the maximum display value is 6000 digits.
