1. 서론
The TRACEABLE Jumbo Calibrated Digital Fridge/Freezer Thermometer (Model AO-94460-73) is designed for precise temperature monitoring in refrigerators, freezers, water baths, heating blocks, and incubators. This device simultaneously displays current, minimum, and maximum temperatures, offering a comprehensive overview of environmental conditions. Its built-in memory stores temperature data, and programmable alarms provide alerts for critical temperature deviations.
주요 특징:
- Simultaneous display of current, minimum, and maximum temperatures.
- Built-in memory for tracking temperature conditions over time.
- Precise high and low temperature alarms, adjustable in 1° increments.
- Submersible temperature probe with a 10-ft (3-m) micro-cable.
- Multiple mounting options: hook-and-loop strips, wall-mount slots, or flip-open stand.
- NIST-traceable calibration certificate included.

3. 설정
3.1. 배터리 설치
- 장치 뒷면에서 배터리 칸을 찾으세요.
- 배터리 덮개를 제거합니다.
- Insert the supplied AAA alkaline battery, ensuring correct polarity (+/-).
- 배터리함 덮개를 단단히 다시 닫으십시오.
3.2. 프로브 배치
The bottle probe is designed to buffer rapid temperature changes, providing a more stable and accurate reading of the stored contents. The 10-ft (3-m) micro-cable allows the probe to be placed inside the monitored environment while the main unit remains outside.
- Place the bottle probe inside the refrigerator, freezer, or other environment where temperature monitoring is required. Ensure the probe is positioned to accurately reflect the temperature of the items being stored.
- The micro-cable is thin enough to allow refrigerator or freezer doors to close without damaging the cable or compromising the seal.

3.3. 본체 장착
The main thermometer unit can be mounted in several ways:
- Hook-and-Loop Strips: Attach the adhesive-backed hook-and-loop strips to the back of the unit and a clean, flat surface (e.g., side of a refrigerator, wall).
- 자석 띠: Use the magnetic strips for attachment to metallic surfaces.
- Wall-Mount Slots: Utilize the integrated slots on the back of the unit to hang it on screws or hooks.
- Flip-Open Stand: For benchtop use, extend the integrated stand on the back of the unit.

4. 사용 설명서
4.1. 전원 켜기/끄기
The unit powers on automatically upon battery installation. There is no dedicated power button. To turn off, remove the battery.
4.2. 온도 측정
The large LCD display shows three temperature readings simultaneously:
- 현재 온도: The real-time temperature measured by the probe.
- Minimum Temperature (MIN): 마지막 재설정 이후 기록된 최저 온도입니다.
- Maximum Temperature (MAX): 마지막 초기화 이후 최고 기온이 기록되었습니다.
4.3. 온도 단위 변환 (°F/°C)
를 누르세요 화씨/섭씨 button (if available, or a similar labeled button) to toggle between Fahrenheit and Celsius temperature scales.
4.4. Viewing and Clearing Min/Max Memory
The thermometer automatically records the minimum and maximum temperatures reached since the last memory reset. These values are continuously displayed.
- To clear the MIN/MAX memory and begin a new recording cycle, press the 분명한 button. The display will show the current temperature for MIN and MAX until new minimum and maximum values are recorded.
4.5. 알람 설정
The thermometer features programmable high and low temperature alarms. An alarm will sound when the temperature exceeds the high set point or falls below the low set point. The alarm continues to sound even if the temperature returns to the non-alarm range until acknowledged.
- 를 누르세요 세트 버튼을 누르면 알람 설정 모드로 들어갑니다.
- 사용하세요 UP 그리고 아래에 arrow buttons to adjust the desired high temperature alarm limit.
- 누르다 세트 again to confirm the high limit and proceed to set the low temperature alarm limit.
- 사용하세요 UP 그리고 아래에 arrow buttons to adjust the desired low temperature alarm limit.
- 누르다 세트 a third time to exit alarm setting mode and save the settings.
- To enable or disable the alarm, press the 알람 ON / OFF button. An alarm icon will typically appear on the display when the alarm is active.
- To silence a sounding alarm, press any button. The alarm will reactivate if the temperature remains outside the set limits.
5. 유지관리
5.1. 청소
Regular cleaning helps maintain the accuracy and longevity of your thermometer.
- Wipe the main unit and probe with a damp cloth. A mild soap solution can be used if necessary.
- Do not use abrasive cleaners or solvents, as these may damage the plastic casing 또는 디스플레이.
- Ensure the main unit does not get wet, as it is not waterproof. The probe is submersible.
5.2. 배터리 교체
When the display becomes dim or the unit stops functioning, it is time to replace the battery. Refer to Section 3.1 for battery installation instructions.
5.3. 프로브 관리
The bottle probe is designed for durability. Avoid sharp bends or kinks in the cable, which could damage the internal wiring. The probe is freezer safe and can remain in the monitored environment continuously.
