The ADS5012H is a versatile, highly practical, cost-effective handheld oscilloscope for the maintenance industry and the R&D industry, with DANIU's real-time sampling rate of up to 500MS/s and 100MHz analog bandwidth.With full trigger function (single, normal, automatic), it can be used freely for both periodic analog signals and non-periodic digital signals. The built-in high voltage protection module can withstand up to 400V continuous voltage and 600V peak voltage. There is no need to worry about the oscilloscope burnout caused by the high voltage not being probed to the 10X position. Large time base scan mode that monitors slow level changes. Equipped with high-efficiency one-button AUTO, the measured waveform can be displayed without complicated adjustment. Display high-definition LCD screen with 2.4-inch 320*240 resolution TFT full-vision technology. Extremely convenient and fast waveform storage function, built-in 64M storage space, can store up to 2000 waveform pictures. The storage process is simple and fast, save the current waveform anytime and anywhere with just one touch. Powerful waveform file manager, support for thumbnail browsing, viewing, detail viewing, page turning, deletion and more. Built-in 3000mah high-quality lithium battery, can be used continuously for 8 hours when fully charged.
