5. Arahan Operasi
The DSO-2202H + AFG offers three primary modes of operation: Oscilloscope, Multimeter, and Arbitrary Function Generator.
5.1 Mod Osiloskop
This mode allows you to visualize and analyze electrical signals. The device features 2 channels and a 200MHz bandwidth.
- Tekan ke Mod butang untuk memilih mod Osiloskop.
- Connect the oscilloscope probe(s) to the circuit under test.
- Gunakan CH1/2 button to switch between channels or view kedua-duanya.
- Adjust the vertical sensitivity (V/div) and horizontal time base (s/div) using the navigation buttons.
- Gunakan Trig/Δ button to set trigger conditions for stable waveform display.
- The Auto button can automatically adjust settings for a stable waveform.

5.2 Mod Multimeter
The multimeter function allows for precise measurements of voltage, arus, rintangan, kemuatan, dan kesinambungan.
- Tekan ke Mod butang untuk memilih mod Multimeter.
- Connect the test leads to the appropriate input jacks (e.g., VΩ+C for voltage/resistance/capacitance, A or mA for current, COM for common).
- Select the desired measurement function (e.g., DC Voltage, Vol. ACtage, Resistance) using the function buttons (F1-F4) or navigation keys.
- Baca nilai ukuran pada paparan.
5.3 Arbitrary Function Generator (AFG) Mode
The AFG allows you to generate various waveforms for testing circuits.
- Tekan ke Mod button to select AFG mode.
- Connect the output of the AFG to the circuit requiring a signal input.
- Use the function buttons (F1-F4) and navigation keys to select waveform type (sine, square, triangle, etc.), frequency, amplitud, dan ofset.
- Adjust parameters as needed for your application.
5.4 Penyimpanan Data
The USB Type-C port can be used for data storage. Connect the device to a computer using a USB Type-C cable to transfer saved waveforms or measurement data.
6. Penyelenggaraan
Proper maintenance ensures the longevity and accuracy of your device.
- Pembersihan: Bersihkan peranti dengan kerap menggunakan kain lembut dan kering. Jangan gunakan pembersih atau pelarut yang melelas.
- Storan: Simpan peranti di tempat yang sejuk dan kering jauh dari cahaya matahari langsung dan suhu yang melampau.
- Penjagaan Bateri: If the device has an internal rechargeable battery, ensure it is charged periodically if stored for long periods to maintain battery health.
- Penjagaan Probe: Inspect probes and test leads for damage before each use. Replace any damaged accessories immediately.
7. Penyelesaian masalah
If you encounter issues with your device, refer to the following common troubleshooting steps.
- Peranti tidak dihidupkan: Ensure the device is charged or connected to a power source. Check the power button for proper engagement.
- Tiada paparan: If the device powers on but the screen is blank, try adjusting the display brightness (if available) or restarting the device.
- Bacaan yang salah: Verify that probes and test leads are correctly connected and not damaged. Ensure the correct measurement mode and range are selected. Calibrate the device if necessary (refer to advanced settings or contact support).
