Overview
it continues the compact and lightweight concept but with a new generation of 3 in 1 multifunction tester: oscilloscope, signal source and multimeter; A small volume of the non-profit grip by a single hand; The suspendingstand was designed to support multi-angle adjustment; Ultra-low-power, Type C charging interface, each 2 hours battery charge allow working one full day or standbytwo months; High-definition color LCD screen display clear and delicate; Minimalist keyboard design simplifyoperation, easy to use.
Features
-Intelligent charging control: Its lithium batteries can be recharged byeither high current-5V/2A or ordinary computer USB interface. Allow while charging, while using, very convenient and handy;
-Ultra-low power design: Type C charging interface, after every recharge of 2 hours, the device can be used continuously for a full day or standby more than two months;
-Large-capacity lithium battery power supply: 18650 replaceable lithium battery power system, free from replace battery;
-5V/2A charger + Type C charging cable: Type C power + data transfer interface, can share the charger and data cable with your mobile phone;
-AUTO one-key test: Magic tool and essential function for test newbie;
-Volume small, one hand holding: The 45 degree suspension bracket design provide you a work station anywhere anytime;
-One key page out, quick compare two groups of reference waveforms + 6 groups of waveforms storage, simple and effective;
-Digital voltmeter function: automatic frequency and amplitude measurement, convenient and worry-free;
-Its cursor measurement functionsupports time and voltage manual measurement, and measure the required waveforms accurately;
-One-click switching its Chinese and English language menu;
-Color LCD screen: exquisite and smooth lines make the waveforms clear and undistorted when magnify;
-Minimalist keyboard design simplify operation, convenient to use;
-Unibody casing: fine touch feeling, favorable impact resistance, outstanding heat resistance, easy to disassemble;
-Self-calibration function: free from level drift after long time unused;
-Universal multimeter function: voltage, current, resistance, diode, capacitor, on-off test;
-Waveform generator output function: output sine, square, triangle, trapezoidal and other waveforms; sine up to 25MHz;
-Function of video help:scan code on back of machine to get help of video course;
-The PC software supports windows7/8/10 32-bit and 64-bit.
