Can freeze at any time waveform display (HOLD function). Comes 1Hz /3.3V square wave test signal source. Waveform storage function: will not lose the waveform after power off. Short-circuit and open-circuit detection: can help the user find out the soldering error. TFT controller recognition function. This kit uses ARM Cortex-M3 processor (STM32F103C8), and includes a 2.4-inch color TFT display screen, can be used as ARM test development board. Can be secondary development on the basis of this kit, for example, it can be changed to Millivoltmeter, data loggers. Packing list: 1 x Digital Oscilloscope 1 x Probe 2 x User Manual(English) 1 x DSO138 acrylic case Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.  Manual measuring,please allow 1-3mm error,thank you.
