The oscilloscope has up to 20 ms / s real-time sampling rate and an analog bandwidth of 5 MHz. Equipped with the high efficiency an automatic knob, the measured waveform can be displayed without complicated adjustment. 2.4 inch color screen, 320 * 240 resolution, displays data clearly for easy reading. Day mode and night mode can be changed according to your own preferences. Built in 1500mAh rechargeable lithium battery can be continuously charged for 3 hours at a time. Memory compression technology, waveform refresh screen not flicker. Extremely convenient and fast waveform storage function. Built-in storage space of 16m, maximum storage of 500 waveform images. Powerful waveform file manager, support for thumbnail browsing, visualization, detail viewing, flip, delete and other functions. High measurement voltage range, 1x can measure 0 40 40 v, 10x can measure 40 800 v. Up to 11 measurement parameters: vpp, vmax, vmin, vavg, vrms, frequent, must +, must-, time +, time-, time. At any time, the waveform display (pause function) is frozen. Full function (single, normal, auto). The oscilloscope is a complete function, high utility, high performance and cost effective handheld oscilloscope for the maintenance industry and the industry. With full trigger function (single, normal, auto), both periodic analog signal and dic odic digital signal can be used freely. Large time base scan mode can monitor slow level changes.
