6. 유지관리
- 청소: 본체와 프로브를 부드러운 천으로 닦으십시오.amp 천. 연마성 세척제나 용매를 사용하지 마십시오.
- 배터리 교체: Replace batteries when the low battery indicator appears on the display. Ensure proper battery type and polarity.
- 저장: When not in use for extended periods, remove the batteries and store the device in a cool, dry place away from direct sunlight and extreme temperatures.
- 재보정: Due to the nature of humidity sensors, periodic recalibration is recommended to maintain accuracy. Refer to the NIST-Traceable certificate for recommended recalibration intervals.
7. 문제 해결
| 문제 | 가능한 원인 | 해결책 |
|---|---|---|
| 화면이 안 나오거나 아주 희미하게 나옵니다. | Dead or weak batteries; incorrect battery installation. | 배터리를 새 배터리로 교체하고 극성이 올바른지 확인하세요. |
| 부정확한 판독 | Sensor contamination; need for recalibration; probe not properly connected. | Clean the probe gently; perform recalibration; ensure probe is securely connected. |
| RS-232 communication failure | Incorrect cable; software settings mismatch; port issue. | Verify cable connection and type; check software communication settings (baud rate, parity); try a different USB/serial port. |
