5.1. 볼륨tage 테스트
- Ensure the alligator clip is securely grounded.
- Carefully touch the probe tip to the circuit or component you wish to test.
- The digital display will show the voltage reading. The LED indicator will illuminate (red for positive, green for negative) to indicate polarity.
- 볼륨이tage exceeds the tester's maximum capacity (90V DC), the display may show an error or an "H" indicating high voltage. Disconnect immediately.

5.2. 연속성 테스트
- Ensure the circuit is de-energized before performing continuity tests.
- Connect the alligator clip to one end of the component or wire to be tested.
- Touch the probe tip to the other end.
- If continuity exists, the LED indicator will light up (typically green for continuity, or red if connected to a positive source through the component) and the display may show a low resistance value or a specific continuity symbol.

5.3. Fuse Testing
- With the circuit energized, connect the alligator clip to a known good ground.
- Touch the probe tip to each test point on the top of the fuse.
- If both sides of the fuse show a voltage reading, the fuse is good. If one side shows voltage and the other does not, the fuse is blown.

6. 유지관리
- 청소: 사용 후에는 깨끗하고 마른 천으로 테스터를 닦아주세요. 연마성 세척제나 용제를 사용하지 마세요.
- 저장: Store the tester in a dry, cool place, away from direct sunlight and extreme temperatures. Always replace the protective probe cover before storage.
- 케이블 검사: Regularly inspect the spring wire and alligator clip for any signs of damage, fraying, or corrosion. Replace if necessary.
7. 문제 해결
| 문제 | 가능한 원인 | 해결책 |
|---|---|---|
| No display/LED light | Poor ground connection; No power in circuit; Faulty tester. | Ensure alligator clip has a solid ground. Verify circuit has power. Test tester on a known live circuit. |
| 부정확한 볼륨tag전자책 읽기 | Poor connection; High resistance in circuit. | Clean connection points. Ensure firm contact with probe. |
| "H" or error message on display | 권tage exceeds 90V DC. | Immediately disconnect the tester. This tester is not designed for voltages 90V DC 이상. |
