3.2 측정 수행
To perform an earth/ground resistance measurement:
- Ensure the unit is powered ON by rotating the dial to the desired measurement mode (Ω).
- cl을 열어라amp 레버를 눌러서 턱을 움직이세요.
- cl을 놓다amp around the earth conductor or ground loop to be measured, ensuring the jaws close completely and smoothly. The flat core ends are designed for optimal contact.
- The meter will automatically begin measuring. The resistance value will be displayed on the LCD.
- If operating in an electrically noisy environment, activate the Noise Filter Function as per the detailed instructions in the full user manual to ensure stable readings.
- To save a reading, use the data storage function. Readings are time and date stamped for easy record-keeping.
The DET14C can measure ground resistance within a range of 0.05 Ω to 1500 Ω, with varying accuracy across sub-ranges:
- 0.05 Ω - 0.99 Ω
- 1.00 Ω - 9.99 Ω
- 10.0 Ω - 99.9 Ω
- 100.0 Ω - 199.9 Ω
- 200 Ω - 400 Ω
- 400 Ω - 600 Ω
- 600 Ω - 1200 Ω
- 1200 Ω - 1500 Ω
4. 유지관리
4.1 청소
To maintain accuracy and prolong the life of your DET14C, regularly clean the unit, especially the clamp jaws and flat core ends. Use a soft, dry cloth. For stubborn dirt, a slightly damp cloth may be used, but ensure no moisture enters the device. Do not use abrasive cleaners or solvents.
4.2 배터리 교체
When the low battery indicator appears on the display, replace the batteries promptly to ensure continued accurate operation. Refer to Section 2.2 for battery installation instructions.
4.3 보관
When not in use, store the Megger DET14C in its protective carrying case in a cool, dry place, away from direct sunlight and extreme temperatures. If storing for extended periods, remove the batteries to prevent leakage.
5. 문제 해결
This section addresses common issues you might encounter with your Megger DET14C. For more detailed troubleshooting, refer to the comprehensive user manual.
일반적인 문제:
- 전원 없음: 배터리 설치를 확인하고 배터리가 방전되지 않았는지 확인하세요.
- 부정확한 판독: CL을 확인amp jaws are fully closed and clean. Verify the conductor is properly positioned within the clamp. Activate the noise filter function if operating in an electrically noisy environment.
- 디스플레이가 응답하지 않음: Try turning the unit off and on again. If the issue persists, replace batteries.
If problems persist after attempting these steps, contact Megger customer support or a qualified service technician.
