1Memory compression technology, waveform refresh screen does not flicker. 2Built-in 16M storage space, the maximum storage of 500 waveform pictures. 3Powerful waveform file manager, support thumbnail browsing, viewing, details view, flip, delete and other functions. 4High measurement voltage range, 1X can measure 0 ~ 40 V, 10X can measure 40 ~ 800V. 5Up to 11 parameters measurement: VPP, Vmax, Vmin, Vavg, Vrms, Frequent, Duty+, Duty-, Time+, Time-, Time. The Oscilloscope is a full function, high utility, high performance and cost-effective handheld oscilloscope for the maintenance industry and the R & D industry. The oscilloscope has a real-time sampling rate of up to 20MS/s and a 5MHz analog bandwidth. With complete triggering function (single, normal, automatic), both the periodic analog signal and the aperiodic digital signal can be used freely. Large time base scanning mode can monitor slow level changes. Equipped with high efficiency one button AUTO, the measured waveform can be displayed without complicated adjustment. Display the High Definition LCD screen equipped with 2.4 inch 320*240 resolution. Extremely convenient and fast waveform storage function, built-in 16MB storage space, the maximum storage of 500 waveform pictures. Powerful waveform file manager, support thumbnail browsing, viewing, details view, flip, delete and other functions. Built in 1200mAh rechargeable lithium battery can be continuously charged for 3 hours at one time. Day mode and night mode can be changed according to their own preferences. Features: 1.
