5. Nastavení

5.1 Nabíjení zařízení

Before initial use, fully charge the oscilloscope. Connect the provided USB data cable to the device's charging port and a 5V power adapter (1A to 4A recommended). The charging indicator will show the charging status.

5.2 Připojení sondy

1. Locate the BNC connector on the oscilloscope.
2. Align the probe's BNC connector with the oscilloscope's input and twist clockwise to secure it.
3. Attach the ground clip of the probe to the circuit's ground point.
4. Select the appropriate attenuation setting (1X or 10X) on the probe based on your measurement requirements. Ensure the oscilloscope's setting matches the probe's attenuation.

6. Provozní režimy

The ASHATA 5012H oscilloscope offers three primary operating modes to suit different measurement needs:

• Automatický režim: This mode is ideal for testing periodic analog signals, such as sinusoidal waveforms. The oscilloscope automatically adjusts settings to display a stable waveform.
• Jediný režim: Use this mode for capturing unexpected, non-periodic events, such as car ignition signals. The oscilloscope triggers once and then stops, allowing for detailed analysis of a single event.
• Normální režim: This mode is suitable for testing digital logic signals, like those from an infrared remote control. It requires a stable trigger condition to display the waveform.

To switch between modes, press the 'MODE' button on the device. The current mode will be indicated on the screen.

7. Údržba

• Čištění: K čištění zařízení používejte měkký, suchý hadřík. Nepoužívejte abrazivní čisticí prostředky ani rozpouštědla.
• Skladování: Store the oscilloscope in its protective case in a cool, dry place when not in use. Avoid extreme temperatures and humidity.
• Péče o baterie: Chcete-li prodloužit životnost baterie, vyvarujte se častého úplného vybíjení baterie. Zařízení pravidelně nabíjejte, i když jej aktivně nepoužíváte.
• Péče o sondu: Handle the probe carefully. Do not bend or twist the cable excessively. Keep the probe tip clean.

8. Řešení problémů

If you encounter issues with your ASHATA 5012H oscilloscope, consider the following basic troubleshooting steps:

• Zařízení se nezapíná: Ensure the battery is charged. Connect the device to a power source using the USB cable and try again.
• Nezobrazuje se žádný průběh: Check if the probe is correctly connected to both the oscilloscope and the circuit. Verify the probe's attenuation setting matches the oscilloscope's setting. Adjust the trigger level and time base settings.
• Nestabilní tvar vlny: Try adjusting the trigger settings (level, mode). Ensure the signal source is stable.
• Nesprávné hodnoty: Calibrate the probe if necessary. Ensure the input voltage does not exceed the maximum test voltage for the selected probe attenuation.

For persistent issues, please refer to the detailed troubleshooting section in the full user manual or contact customer support.
