A3005 Digital Multimeter Mini Pen Type Professional Multimeter Pen 4000 Count with Non-Contact Automatic AC/DC Voltage Ohm Diode Continuity Voltage Tester For Tools A. Overview: This digital pen is a small 3 3/4 bit True RMS automatic scanning digital instrument. Depending on the difference between voltage and resistance, the operator does not need to turn the dial to select the function, due to its automatic identification measurement. Stable performance, high precision, high reliability, clear reading, overload protection function is achieved. And this meter is charged by AAA 1.5V low battery. and with large LCD screen, beautiful backlight making the display clear, convenient, it is appreciated by most people. This new type of meter also automatically identifies DC voltage, AC voltage, resistance, continuity, without any selection, in addition to having the function of manually switching to measure electric field induction and fire wire discrimination. it will be an ideal tool for radio enthusiasts and families, thanks to its superior performance.
