Digital Oscilloscope/Multimeter/Generator GD188 GVDA. How to use an oscilloscope and multimeter?
Digital Oscilloscope | Digital Multimeter | Signal generator
The GD188 GVDA battery-powered digital multimeter from GVDA has an excellent design and good electrical characteristics. This is a digital multimeter from Aliexpress. It includes a digital oscilloscope and a signal generator (frequency generator). From the video you will learn how to use a multimeter and how to use an oscilloscope with a generator. This measuring instrument is designed to measure electrical parameters such as current measurement, voltage measurement, resistance measurement, frequency and duty cycle measurement, waveform acquisition and frequency signal generation. This measuring device has other functions (checking diodes and LEDs, continuity of circuits, storing measured values and oscillograms in the internal memory of the device, measuring peak and relative values of electrical parameters).
