2.3 Accensione/Spegnimento

Premere e tenere premuto il tasto Pulsante di accensione located on the side of the device to turn it on or off. The device features an auto-shutdown function, adjustable from 15 minutes to 1 hour, to conserve battery life.

3. Funzionamento

3.1 Interfaccia generale e navigazione

The DST-210 features a 2.8-inch TFT color screen. Use the central Quadrante di funzione E ENTRARE button for mode selection and parameter adjustment. The MODALITÀ 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.

3.3.1 Specific Multimeter Measurements

• Volume AC/DCtage: Select V~ or V- on the dial. Connect leads in parallel to the circuit.
• Corrente CA/CC: Select A~ or A- on the dial. Connect leads in series with the circuit. Use 10A or mA input as appropriate.
• Resistenza (Ω): Select Ω on the dial. Connect leads across the component.
• Test di continuità: Select the continuity symbol on the dial. A buzzer sounds for low resistance.
• Prova del diodo: Select the diode symbol. Measures forward voltage goccia.
• Frequenza (Hz): Select Hz on the dial.
• Capacità: Select the capacitance symbol.
• Temperatura: Requires a K-type thermocouple (not included).
• Rilevamento del filo fase/neutro: Use the dedicated function on the dial.
