4. 설정
4.1 배터리 설치
The digital torque meter requires 3 AAA batteries (not included) for operation.
- 장치 뒷면에서 배터리함을 찾으세요.
- Open the battery cover using the provided screwdriver if necessary.
- 배터리 3개를 넣고, 배터리 칸 안쪽에 표시된 대로 극성(+/-)을 올바르게 맞춰 넣으세요.
- 배터리 덮개를 단단히 닫으세요.
4.2 라쳇 렌치에 부착하기
The digital torque meter is designed to be used in conjunction with a standard ratchet wrench. It effectively converts your existing wrench into a digital torque wrench.
- Select a ratchet wrench with a square drive size compatible with your torque meter model (e.g., 1/4", 3/8", or 1/2").
- Insert the square drive of the torque meter into the square hole of the ratchet wrench.
- Ensure the connection is secure. If necessary, use appropriate adapters (e.g., 1/2" to 3/8" adapter) for compatibility.
Note: The ratchet wrench and any necessary adapters are typically purchased separately.
5. 사용 설명서

- Peak (P) Mode: Captures and displays the maximum torque value achieved during a measurement.
모드를 전환하려면 누르세요. PT 단추.
5.3 토크 단위 선택
The device supports four common torque units:
- kgf.cm
- Nm(뉴턴미터)
- Ibf.ft (Pound-force foot)

- 저장: Store the torque meter in its protective case in a dry, cool place when not in use. Remove batteries if storing for extended periods to prevent leakage.
- 충격 방지: Protect the device from drops and strong impacts, as this can affect its accuracy and functionality.
7. 문제 해결
| 문제 | 가능한 원인 | 해결책 |
|---|---|---|
| 장치의 전원이 켜지지 않습니다. | 배터리가 방전되었거나 잘못 설치되었습니다. | 배터리 극성을 확인하세요. 새 AAA 배터리로 교체하세요. |
| 부정확한 판독값. | Device not properly calibrated (unlikely for new device) or damaged. | Ensure proper connection to the wrench. If issues persist, contact customer support. |
| Alarm not sounding/lighting up. | Target torque not set or reached. | Verify the target torque setting. Ensure the applied torque exceeds the set value. |
8. 사용자 팁
- Always ensure the digital torque meter is securely attached to your ratchet wrench before use.
- For critical applications, perform a test measurement on a known fastener to confirm accuracy.
- When setting target torque, consider the material and specifications of the fastener to avoid over-tightening or damage.
- The device is suitable for a wide range of applications, but always use the correct model and torque range for the task at hand.
