소개
This manual provides detailed instructions for the proper use, setup, and maintenance of your Traceable® Digital Thermometer with Bottle Probe. This precision instrument is designed for accurate temperature monitoring, particularly in environments requiring stable temperature readings such as refrigerators, freezers, and water baths. It features a sealed bottle probe that mimics the temperature of stored liquids, preventing false alarms from temporary door openings.
Each unit comes with a NIST-traceable certificate from an ISO/IEC 17025:2017 (1750.01) accredited calibration laboratory, ensuring accuracy and reliability.

그림 1: 전면 view of the Traceable Digital Thermometer with Bottle Probe. The display shows current, minimum, and maximum temperatures. The bottle probe is connected via a cable.
Figure 2: The Traceable Digital Thermometer with its bottle probe positioned inside a refrigerator, demonstrating its typical application for stable temperature monitoring.
The Traceable Digital Thermometer is equipped with a triple-display, allowing simultaneous viewing of the current, minimum, and maximum temperatures. The sealed bottle probe is filled with a non-toxic glycol solution, which buffers temperature changes, providing a more accurate representation of the temperature of stored contents rather than ambient air fluctuations.
- Triple-Display: Shows high, low, and current temperature simultaneously.
- 최소/최대 메모리: Stores minimum and maximum temperatures until cleared.
- Bottle Probe: Sealed bottle filled with glycol solution for stable temperature readings, ideal for refrigerator/freezer monitoring.
- NIST 추적 가능 인증서: Ensures accuracy and compliance with regulatory requirements.
- 다양한 배치: Features a fold-out stand for desktop use, magnetic strips for metal surfaces, and a wall-mount keyhole.
설정 및 설치
- 배터리 설치: The thermometer requires one AA battery (included). Open the battery compartment on the back of the unit and insert the battery, observing polarity.
- 프로브 배치:
- Place the bottle probe inside the environment you wish to monitor (e.g., refrigerator, freezer). Ensure the probe is positioned where it will accurately reflect the temperature of the contents.
- Route the probe cable carefully to avoid pinching or damage.
- 유닛 배치:
- Use the fold-out stand to place the unit on a flat surface.
- Utilize the magnetic strips on the back to attach the unit to a metal surface (e.g., refrigerator door).
- Hang the unit on a wall using the keyhole slot.
- 초기 전원 켜기: The unit should power on automatically once the battery is installed. The display will show the current temperature, along with the minimum and maximum recorded temperatures since the last reset.

작동 지침
디스플레이 기능
The thermometer's display shows three temperature readings simultaneously:
- 현재 온도: The real-time temperature reading from the bottle probe.
- 최저 온도: The lowest temperature recorded since the last memory clear.
- 최대 온도: The highest temperature recorded since the last memory clear.
버튼 기능
| 단추 | 기능 |
|---|---|
| 메모리 지우기 | Press to clear the stored MIN and MAX temperature readings. The display will update with the current temperature as the new MIN/MAX. |
| 방법 | Toggles between Celsius (°C) and Fahrenheit (°F) temperature units. |
| ALARM ON / OFF 스위치 | Activates or deactivates the audible alarm function. When activated, the alarm will sound if the temperature goes outside the set high/low alarm limits. |
| RESET (on back) | A small button on the back of the unit (often recessed) used to perform a hard reset of the device, typically requiring a pointed object like a paperclip. This will clear all settings and memory. |
| LO/HI (on back) | Buttons on the back of the unit used to set the low and high temperature alarm limits. Refer to the alarm setting section for details. |
Setting Alarms (Optional)
The thermometer can be configured to sound an alarm if the temperature exceeds or falls below user-defined limits. The alarm setting buttons (LO and HI) are located on the back of the unit.
- Ensure the ALARM ON/OFF switch is in the OFF position before setting limits.
- 를 누르고 계세요 LO button on the back of the unit. The LO temperature will flash. Use the 방법 button on the front to adjust the desired low alarm limit. Release the LO button to set.
- 를 누르고 계세요 HI button on the back of the unit. The HI temperature will flash. Use the 방법 button on the front to adjust the desired high alarm limit. Release the HI button to set.
- Once limits are set, slide the 알람 ON / OFF switch to the ON position to activate the alarm.
- If the temperature goes outside the set range, the alarm will sound. To silence the alarm, slide the ALARM ON/OFF switch to OFF.

유지 보수 및 관리
- 청소: Wipe the unit and probe with a damp cloth. Do not immerse the main unit in water. The bottle probe is sealed and can be wiped clean.
- 배터리 교체: When the display becomes dim or erratic, replace the AA battery. Ensure proper polarity.
- 저장: Store the thermometer in a dry environment away from extreme temperatures when not in use for extended periods.
- 구경 측정: This thermometer comes with a NIST-traceable certificate. For continued accuracy and compliance, periodic re-calibration by an accredited laboratory is recommended, especially in regulated environments.
문제 해결
| 문제 | 가능한 원인 | 해결책 |
|---|---|---|
| 디스플레이가 없거나 어둡습니다 | 배터리 방전 또는 배터리 잔량 부족; 배터리 설치 오류. | Replace the AA battery, ensuring correct polarity (+/-). |
| 부정확한 판독 | Probe not properly placed; probe damage; unit malfunction. | Ensure the bottle probe is fully immersed in the monitored environment. Check the probe cable for visible damage. If issues persist, contact customer support. |
| 알람이 울리지 않음 | Alarm switch is OFF; alarm limits not set correctly. | Slide the ALARM ON/OFF switch to ON. Verify that the LO and HI alarm limits are set to the desired range. |
| MIN/MAX readings not clearing | MEMORY CLEAR button not pressed firmly or unit malfunction. | Press the MEMORY CLEAR button firmly. If it still doesn't clear, try a hard reset using the RESET button on the back. |
