3. Funcionament

3.1 General Interface and Navigation

The DST-210 features a 2.8-inch TFT color screen. Use the central Dial de funció i ENTRAR button for mode selection and parameter adjustment. The MODE button switches between main functions (Oscilloscope, Multimeter, Signal Generator) or sub-modes within a function. The RUN/SAVE button is used for starting/stopping measurements or saving data.
