5. Подешавање
Follow these steps to set up your VOLTCRAFT DOV1004 oscilloscope for the first time.
- Распакивање: Carefully remove the oscilloscope and all accessories from the packaging. Retain the packaging for future transport or storage.
- Прикључак за напајање: Connect the USB Type-C power adapter to the power input port on the rear of the oscilloscope and then plug the adapter into a suitable power outlet.
- Укључено: Press the power button on the front panel to turn on the oscilloscope. The display should illuminate.
- Веза сонде: Connect the oscilloscope probes to the desired input channels (CH1-CH4) using the BNC connectors. Ensure a secure connection.
- Компензација сонде: Before taking measurements, it is recommended to compensate your probes. Connect the probe to the probe compensation output (usually a dedicated terminal on the front panel, often labeled "Probe Comp" or similar, or use a known square wave source). Adjust the probe's compensation trimmer until a flat-top square wave is displayed on the screen.
- Почетна подешавања: The oscilloscope may perform an automatic self-calibration upon first power-on. You can adjust basic settings like language, date, and time through the system menu on the touchscreen.
