The multimeter function allows for precise measurement of various electrical parameters. To switch to multimeter mode, press the dedicated oscilloscope/multimeter switch button (9).

• Vol. ACtage (V): Connect the test leads to the VΩHz-f and COM jacks. Select the AC voltage gear and measure across the circuit.
• DC Voltage (V): Connect the test leads to the VΩHz-f and COM jacks. Select the DC voltage gear and measure across the circuit, observing polarity.

• Corrent alterna (A): Connect the test leads to the 10A or mA jack and COM. Select the appropriate AC current gear and measure in series with the circuit.
• Corrent DC (A): Connect the test leads to the 10A or mA jack and COM. Select the appropriate DC current gear and measure in series with the circuit.
• Prova de díode: Enter the diode gear, touch the positive and negative electrodes of the diode with the test leads.
• Resistència (Ω): Enter the resistance gear, measure the resistance value on both sides of the component.

• Capacitat (F): Enter the capacitor gear and contact both ends of the capacitor. For safety reasons, it is necessary to short-circuit the capacitor before measurement.
• Buzzer (Continuity): Enter the buzzer gear, detect on and off, and issue a beep, indicating that the fuse line is unobstructed.

5.2 Funció de l'oscil·loscopi

The oscilloscope function allows for real-time waveform visualization and analysis. To switch to oscilloscope mode, press the dedicated oscilloscope/multimeter switch button (9).

5.2.1 Dual Channel Waveform Detection

The AOS03 supports dual-channel input (CH1 and CH2), enabling simultaneous display and comparison of two waveforms. This feature enhances problem diagnosis and signal detection accuracy.

Set and connect to the dual-channel input port, select automatic or manual measurement, and press the SAVE button (8) for 2 seconds to save the waveform.

5.2.2 XY Display Mode

To enter XY display mode, navigate to the fifth page of the extended function menu. Press F1 to select X-Y. This mode displays the frequency relationship between CH1 and CH2, producing Lissajous figures of various shapes.

5.2.3 Ordinador View Forma d'ona

The AOS03 allows you to view saved waveforms on a computer. Enter the menu on the third page, press F3 to enter the data saving mode. Connect the device to your computer using the USB data cable. The device will appear as a USB disk. Open the 'Pic' folder on the disk to view the saved waveform images.

5.3 Funció del generador de senyals

The built-in signal generator can output various waveforms for testing and calibration purposes.

5.3.1 Waveform Output

To output a signal waveform, enter the menu on the sixth page. Press F1 to enter the extended application, select 'signal output', and press the MENU key to confirm and start generating the waveform.

6.3 Neteja

Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents, as they may damage the casing o pantalla.

7. Solució De Problemes

7.1 Current Measurement Precaution

IMPORTANT: When measuring current, the multimeter must always be connected in series with the circuit. Incorrect connection (e.g., in parallel) can damage the device and the circuit.

When measuring electric current, pay close attention to the connection method. Do not mix current and voltage measurement modes. Use the multimeter's current file, choose an appropriate range. If the current value is unknown, start with a larger range. If the multimeter displays "1", it indicates an over-range condition. Insert the red pen into the mA hole, the black pen into the COM hole, then disconnect the circuit and connect the pens in series to measure.
