1. はじめに
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.
主な特徴:
- 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. セットアップ
3.1. バッテリーの取り付け
- ユニットの背面にある電池ボックスを見つけます。
- 電池ボックスのカバーを取り外します。
- Insert the supplied AAA alkaline battery, ensuring correct polarity (+/-).
- 電池収納部のカバーをしっかりと取り付けてください。
3.2. Probe Placement
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. 本体の取り付け
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).
- Magnetic Strips: 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. 操作手順
4.1. 電源のオン/オフ
The unit powers on automatically upon battery installation. There is no dedicated power button. To turn off, remove the battery.
4.2. 温度の読み方
The large LCD display shows three temperature readings simultaneously:
- 現在の気温: The real-time temperature measured by the probe.
- 最低気温（MIN）: 前回のリセット以降に記録された最低気温。
- 最高温度（MAX）： 前回のリセット以降に記録された最高気温。
4.3. 温度単位の切り替え（°F/°C）
を押す °F/°C 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 クリア button. The display will show the current temperature for MIN and MAX until new minimum and maximum values are recorded.
4.5.アラームの設定
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.
- を押す セット ボタンを押してアラーム設定モードに入ります。
- 使用 UP そして 下 arrow buttons to adjust the desired high temperature alarm limit.
- プレス セット again to confirm the high limit and proceed to set the low temperature alarm limit.
- 使用 UP そして 下 arrow buttons to adjust the desired low temperature alarm limit.
- プレス セット a third time to exit alarm setting mode and save the settings.
- To enable or disable the alarm, press the アラームのオン/オフ 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. メンテナンス
5.1. 清掃
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.
- 研磨剤入りの洗剤や溶剤はプラスチックの表面を傷つける恐れがあるので使用しないでください。asing またはディスプレイ。
- Ensure the main unit does not get wet, as it is not waterproof. The probe is submersible.
5.2. バッテリーの交換
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. プローブのケア
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.
