4. 설정
4.1 배터리 설치
- 멀티미터 뒷면에서 배터리함을 찾으세요.
- Using a screwdriver, carefully open the battery cover.
- Insert one 9V 6F22 battery, ensuring correct polarity. (Battery not included)
- 배터리 커버를 교체하고 나사로 고정합니다.
4.2 테스트 리드 연결
- 멀티미터의 전원이 꺼져 있는지 확인하세요.
- 검정색 테스트 리드를 공통(COM) 입력 잭에 삽입하십시오.
- Insert the red test lead into the appropriate input jack for your measurement (e.g., for LCR measurements, use the designated LCR input).
5. 사용 설명서
5.1 전원 켜기/끄기
를 누르세요 전원 버튼 (usually marked with a circle and a vertical line) to turn the multimeter on. Press it again to turn the device off.
5.2 측정 기능 선택
중앙 부분을 회전시키세요 로터리 스위치 to select the desired measurement function (C for Capacitance, L for Inductance, R for Resistance) and the appropriate range. Start with a higher range if the value is unknown to prevent overloading.
5.3 측정 수행
- After selecting the function and range, connect the test leads to the component you wish to measure.
- For resistance measurements, you may need to use the ZERO ADJ. knob to zero out the resistance of the test leads before connecting to the component.
- LCD 화면에 표시된 측정값을 읽습니다.
5.4 데이터 홀드 기능
를 누르세요 DH Button to freeze the current reading on the display. Press it again to release the hold function and resume live readings.
6. 유지관리
- 멀티미터를 깨끗하고 건조하게 유지하십시오. 부드러운 천을 사용하십시오.amp 청소할 때는 천을 사용하십시오. 연마성 세제나 용제를 사용하지 마십시오.
- 본 기기는 직사광선과 극한의 온도를 피해 시원하고 건조한 곳에 보관하세요.
- 장기간 기기를 사용하지 않을 경우 누액을 방지하기 위해 배터리를 분리하십시오.
- Regularly check the test leads for any signs of wear or damage. Replace them if necessary.
7. 문제 해결
If you encounter issues with your BM4070 multimeter, refer to the following common problems and solutions:
- 기기의 전원이 켜지지 않습니다: 배터리가 올바르게 설치되었는지, 충전량이 충분한지 확인하십시오. 필요한 경우 배터리를 교체하십시오.
- 판독값이나 'OL'이 표시되지 않음: Ensure the test leads are properly connected to the component and the correct measurement function and range are selected. 'OL' (Overload) indicates the measured value exceeds the selected range; switch to a higher range.
- 부정확한 판독값: Check for proper test lead connection. Ensure the ZERO ADJ. knob is correctly set for resistance measurements. Verify the component is functioning correctly.
