1. Введение
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.
Основные характеристики:
- 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.
2. Содержимое упаковки
Убедитесь, что все перечисленные ниже предметы присутствуют и находятся в исправном состоянии:
- TRACEABLE Jumbo Calibrated Digital Fridge/Freezer Thermometer (Model AO-94460-73)
- 1 5-mL Bottle Probe (submersible)
- Сертификат калибровки, соответствующий стандартам NIST, с указанием данных.

3. Настройка
3.1. Установка аккумулятора
- Найдите батарейный отсек на задней панели устройства.
- Снимите крышку батарейного отсека.
- Insert the supplied AAA alkaline battery, ensuring correct polarity (+/-).
- Надежно закройте крышку батарейного отсека.
3.2. Размещение зонда
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. Монтаж основного блока
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).
- Магнитные полосы: 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. Инструкция по эксплуатации
4.1. Включение/выключение питания
The unit powers on automatically upon battery installation. There is no dedicated power button. To turn off, remove the battery.
4.2. Измерение температуры
The large LCD display shows three temperature readings simultaneously:
- Текущая температура: The real-time temperature measured by the probe.
- Минимальная температура (МИН): Самая низкая температура, зафиксированная с момента последнего сброса показаний.
- Максимальная температура (МАКС): Самая высокая температура, зафиксированная с момента последнего сброса показаний.
4.3. Единицы измерения температуры переключения (°F/°C)
Нажмите °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 ПРОЗРАЧНЫЙ button. The display will show the current temperature for MIN and MAX until new minimum and maximum values are recorded.
4.5. Установка будильника
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.
- Нажмите НАБОР кнопку для входа в режим настройки будильника.
- Используйте UP и ВНИЗ arrow buttons to adjust the desired high temperature alarm limit.
- Нажимать НАБОР again to confirm the high limit and proceed to set the low temperature alarm limit.
- Используйте UP и ВНИЗ arrow buttons to adjust the desired low temperature alarm limit.
- Нажимать НАБОР a third time to exit alarm setting mode and save the settings.
- To enable or disable the alarm, press the БУДИЛЬНИК ВКЛ / ВЫКЛ 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. Техническое обслуживание
5.1. Уборка
Regular cleaning helps maintain the accuracy and longevity of your thermometer.
- Протрите основной блок и проверьте его с помощью AD.amp ткань. При необходимости можно использовать слабый мыльный раствор.
- Не используйте абразивные чистящие средства или растворители, так как они могут повредить пластик.asinг или дисплей.
- Ensure the main unit does not get wet, as it is not waterproof. The probe is submersible.
5.2. Замена батареи
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. Probe Care
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.
6. Поиск Неисправностей
If your thermometer is not functioning as expected, please refer to the following common issues and solutions:
| Проблема | Возможная причина | Решение |
|---|---|---|
| Нет дисплея или тусклый дисплей | Разряженная или неправильно установленная батарея | Вставьте батарейку типа AAA, соблюдая полярность. |
