4. 설정

4.1. 배터리 설치

The Metrel MD9231 is powered by two 1.5 V AAA batteries. To install or replace batteries:

1. 측정기의 전원이 꺼져 있는지 확인하고 입력 단자에서 모든 테스트 리드를 분리하십시오.
2. 측정기 뒷면에서 배터리 덮개를 찾으세요.
3. 드라이버를 사용하여 덮개를 고정하는 나사를 풉니다.
4. Remove the cover and insert two new 1.5 V AAA batteries, observing the correct polarity (+/-) as indicated inside the compartment.
5. 배터리함 덮개를 다시 씌우고 나사를 단단히 조이십시오.

Always use fresh batteries of the specified type. Dispose of old batteries responsibly according to local regulations.

5. 사용 설명서

5.1. 전원 켜기/끄기

To turn the meter ON, rotate the function switch from the 'OFF' position to any desired measurement function. To turn the meter OFF, rotate the function switch back to the 'OFF' position. The meter features an auto power-off function to conserve battery life, which will activate after a period of inactivity.

5.2. 기능 선택

Use the rotary switch to select the desired measurement function. The available functions include:

• AC/DC 볼륨tag전자(V): 부피 측정용tage 최대 1000V.
• 교류/직류 전류(A): For measuring current up to 1000 A using the clamp 턱.
• 저항(Ω): For measuring resistance.
• 연속성()))): For checking circuit continuity with an audible indicator.
• 다이오드 테스트(▶|): 다이오드 테스트용.
• Capacitance (µF): 정전 용량을 측정하기 위해.
• 주파수(Hz): For measuring frequency.
• VFD (Variable Frequency Drive): For accurate measurements in VFD environments.
• NCV(비접촉 Voltag이자형): For detecting live conductors without physical contact.

5.3. 측정하기

For Current Measurement (AC/DC A):

1. Rotate the function switch to the AC A or DC A position.
2. cl을 열어라amp 레버를 눌러 턱을 움직입니다.
3. Encircle only one conductor with the clamp 턱. 턱이 완전히 닫혔는지 확인하세요.
4. LCD 디스플레이의 현재 값을 읽습니다.

볼륨tage, Resistance, Capacitance, Diode, and Frequency Measurements:

1. Rotate the function switch to the desired V, Ω, µF, or Hz position.
2. Insert the black test lead into the 'COM' terminal and the red test lead into the 'VΩHz' terminal.
3. 테스트 프로브를 테스트 대상 회로 또는 부품에 연결하십시오.

7. 문제 해결

MD9231 사용 중 문제가 발생하면 다음의 일반적인 문제 및 해결 방법을 참조하십시오.

• 미터 전원이 켜지지 않습니다:
  Check battery installation and ensure batteries are not depleted. Replace batteries if necessary. Ensure the rotary switch is not in the 'OFF' position.
• No reading or 'OL' (Overload) displayed:
  Ensure test leads are properly connected and making good contact with the circuit. Verify the selected function and range are appropriate for the measurement. If measuring current, ensure only one conductor is within the clamp 턱.
• 부정확한 판독값:
  Check battery level. Ensure test leads are not damaged. Verify the correct function is selected. Environmental factors (e.g., strong electromagnetic fields) can affect readings.
• 디스플레이가 어둡거나 깜빡거립니다:
  배터리를 교체하세요.
