4. Kurulum

4.1. Açma/Kapama

Press and hold the power button (usually located on the top or side) to turn the device on or off. Ensure the battery is sufficiently charged or connected to a power source.

4.2. Probların Bağlanması

Connect the oscilloscope probe to the input BNC connector. Ensure the probe's ground clip is securely connected to the circuit's ground reference. For signal generation, connect the output cable to the designated signal output port.

4.3. Initial Calibration (if applicable)

Some probes may require compensation. Connect the probe to the calibration output (if available) and adjust the probe's compensation screw until a stable square wave is displayed.

5. Cihazı Çalıştırma

  • Adjusting Vertical Sensitivity (Volts/Div): Use the navigation arrows to adjust the vertical scale, changing the voltage represented by each vertical division on the grid.
  • Adjusting Time Base (Sec/Div): Use the navigation arrows to adjust the horizontal scale, changing the time represented by each horizontal division.
  • Tetikleyici Ayarları: Basmak TETİK to access trigger options. Use KENAR to select rising or falling edge triggering. Adjust the trigger level using navigation arrows to stabilize the waveform.
  • AC/DC Bağlantısı: Basmak AC/DC to switch between AC coupling (blocks DC component) and DC coupling (shows full signal including DC offset).
  • Prob Zayıflaması: Sağlamak 1X/10X setting on the device matches the physical attenuation setting on your probe.
  • Dalga biçimlerini kaydetme: Basın KAYDETMEK button to store the current waveform data.

5.2. Signal Generator Mode

The ET120MPro can generate various waveforms for testing circuits. Access this mode via the main menu or a dedicated function button (if available).

  • Dalga Formu Türünü Seçme: Use navigation buttons to choose between Sine, Ramp, and Square waveforms as shown in the product overview görüntü.
  • Frekans Ayarı: Adjust the output frequency using the navigation arrows. The device supports frequencies up to 3MHz.
