5. ترتیب کول
۱. ابتدايي چارج کول
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. د پلټنې اتصال
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. عملیاتي لارښوونې
6.1. بریښنا فعال/بند
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
The ET120M supports three scan modes:
- اتومات: Automatically adjusts time base and vertical amplitude for a stable waveform display. Press the آټو button for one-key waveform adaptation.
- نورمال: Displays a waveform only when a trigger condition is met.
- واحد: Captures and displays a single waveform when a trigger condition is met, then stops.

6.4. Parameter Measurement
The device can automatically measure 12 different waveform parameters. Access these measurements through the menu system. Parameters include Peak-to-Peak Voltage (Vpp), Root Mean Square Voltage (Vrms), Average Voltage (Vavg), Peak Voltage (Vp), Maximum Voltage (Vmax), Minimum Voltage (Vmin), Frequency (F), Period (T), Positive Pulse Width (T+), Negative Pulse Width (T-), Positive Duty Cycle (Du+), and Negative Duty Cycle (Du-).

6.7. Adjusting Waveform Parameters
You can manually adjust various waveform display parameters to fine-tune your measurements:
- د وخت اساس: Adjusts the horizontal scale (time per division).
- Amplitude (Vertical Sensitivity): Adjusts the vertical scale (volts per division).
- Trigger Slope: Sets the trigger to rising or falling edge.
- د محرک کچه: حجم ټاکيtage level at which the waveform is triggered.

7. ساتنه
7.1. پاکول
To clean the device, use a soft, dry cloth. For stubborn dirt, a slightly damp د نرم صابون سره ټوکر کارول کیدی شي، ډاډ ترلاسه شي چې مایع وسیله ته ننوځي. د کثافاتو پاکونکي یا محلول مه کاروئ.
7.2. ذخیره کول
When not in use for extended periods, store the oscilloscope in a cool, dry place, away from direct sunlight and extreme temperatures. It is recommended to store it in the provided cloth bag to protect it from dust and scratches.
7.3. د بیټرۍ پاملرنه
To prolong battery life, avoid fully discharging the battery frequently. If storing for a long time, charge the battery to approximately 50% every few months.
8. ستونزه حل کول
If you encounter issues with your ET120M oscilloscope, refer to the following common problems and solutions:
- وسیله نه فعالیږي: ډاډ ترلاسه کړئ چې بیټرۍ چارج شوې ده. د USB چارج کولو کیبل وصل کړئ او بیا هڅه وکړئ.
- هیڅ څپې بڼه نه ده ښودل شوې: Check probe connection. Ensure the probe is properly connected to the circuit under test. Adjust vertical sensitivity and time base settings. Try the AUTO function.
- Unstable waveform: Adjust the trigger level and trigger slope. Ensure the trigger mode is appropriate for the signal.
- ناسم اندازه ګیري: Verify probe attenuation setting (1X/10X) matches the device setting. Perform a probe compensation if necessary (refer to advanced operation in a full manual).
