3. 사용 설명서
3.1. 전원 켜기/끄기
전면 패널의 전원 버튼을 눌러 오실로스코프를 켜거나 끄십시오.
3.2. Basic Waveform Display
After powering on, connect a signal to CH1 or CH2. Use the Vertical (Position and Scale) and Horizontal (Position and Scale) knobs to adjust the waveform's position and size on the screen. The oscilloscope features a 110MHz bandwidth and 1GSa/s real-time sampling rate for accurate signal capture.
3.3. Triggering
The Trigger section allows you to stabilize repetitive waveforms. Adjust the Trigger Level knob to set the voltage threshold at which the oscilloscope starts acquiring data. Use the Trigger Menu button to access advanced trigger settings.
3.4. 측정
Press the 'Measure' button to access automatic measurement functions. The oscilloscope can display various parameters such as frequency, peak-to-peak voltage, RMS 볼륨tage, 그리고 그 외 더 많은 것들.
3.5. 데이터 저장
The USB Host interface on the front panel allows you to save waveform data, screenshots, and settings to a USB flash drive. The storage depth for acquired waveforms is not less than 10K samp링 포인트.
4. 유지관리
4.1. 청소
To clean the oscilloscope, use a soft, dry cloth. For stubborn dirt, a cloth lightly dampened with water or a mild cleaning solution can be used. Avoid using abrasive cleaners or solvents that could damage the casin화면 또는 플러그를 뽑으십시오. 청소하기 전에 기기의 전원이 꺼져 있고 플러그가 뽑혀 있는지 확인하십시오.
4.2. 보관
Store the oscilloscope in a clean, dry environment away from direct sunlight, extreme temperatures, and high humidity. When not in use for extended periods, disconnect all probes and power cables.
5. 문제 해결
- 전원 없음: Ensure the power cord is securely connected to both the oscilloscope and the power outlet. Check the power button.
- 파형 표시 없음: Verify that the input signal is connected correctly to CH1 or CH2. Adjust the Vertical Scale (V/div) and Horizontal Scale (s/div) knobs to bring the waveform into view. Check the trigger settings.
- 불안정한 파형: Adjust the Trigger Level and Trigger Mode settings to stabilize the waveform. Ensure the trigger source is correctly selected.
- 잘못된 측정: Calibrate probes if necessary. Ensure the input coupling (AC/DC) is appropriate for the signal being measured.
- 장치 오작동: If the oscilloscope does not function correctly upon receipt, contact customer support for immediate assistance. The manufacturer offers replacement for new items at once for such issues.
