5. Орнотуу

5.1. Баштапкы заряддоо

Before first use, fully charge the built-in lithium battery using the provided USB charging cable and a standard USB power adapter (not included). The charging indicator will show the charging status.

5.2. Зонд байланышы

Connect the oscilloscope probe to the BNC input connector on the top of the device. Ensure the connection is secure. Set the probe attenuation switch (if applicable) to the desired setting (e.g., 1X or 10X) and match this setting on the oscilloscope via the 1X/10X button.

6. Иштөө нускамалары

6.1. Күйгүзүү/өчүрүү

Press and hold the power button (usually located on the side or top) to turn the device on or off.

6.2. Basic Waveform Acquisition

After powering on, connect the probe to the circuit under test. The oscilloscope will display the waveform. Use the directional buttons to navigate menus and adjust settings.

6.3. Waveform Acquisition Modes

ET120M үч сканерлөө режимин колдойт:

• Авто: Automatically adjusts time base and vertical amplitude for a stable waveform display. Press the АВТО button for one-key waveform adaptation.
• Кадимки: Displays a waveform only when a trigger condition is met.
• Бойдок: Captures and displays a single waveform when a trigger condition is met, then stops.
