Features: 1. New upgrade, goodbye to the battery era, convenient and economical with USB cable, lithium charging, safe and more economical! 2. Flashlight illumination: in the dark environment, no longer afraid of invisible measurement of the location to eliminate the danger of electric shock, to assist the night measurement work. 3.Intelligent sensor touch screen, like a cell phone, touch screen use, VA color anti-display screen so that the panel clear touch screen display 4.1000V20A special tip very fine general-purpose soft silicone meter pen, high temperature resistance and good toughness of high- meter pen to use with confidence 5.NCV non-contact power measurement: non-contact and safer, with NCV sensing at the induction, the closer the power supply, the more urgent the alarm flashlight at the flashing red 6. A variety of functional measurements: AC / DC voltage measurement, resistance measurement, diode measurement, measurement of capacitance (capacitance needs to be discharged before measurement), buzzer measurement, AC / DC current measurement, temperature measurement.
