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.
Кључне карактеристике:
- 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. Садржај пакета
Verify that all items listed below are present and in good condition:
- TRACEABLE Jumbo Calibrated Digital Fridge/Freezer Thermometer (Model AO-94460-73)
- 1 5-mL Bottle Probe (submersible)
- NIST-следљиви калибрациони сертификат са подацима
- Hook-and-loop strips for mounting
- Magnetic strips for mounting
- Једна ААА алкална батерија
3. Подешавање
3.1. Инсталација батерије
- Пронађите одељак за батерију на задњој страни уређаја.
- Уклоните поклопац одељка за батерије.
- Insert the supplied AAA alkaline battery, ensuring correct polarity (+/-).
- Вратите поклопац одељка за батерије безбедно.
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. Монтирање главне јединице
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. Упутство за употребу
4.1. Укључивање/искључивање
The unit powers on automatically upon battery installation. There is no dedicated power button. To turn off, remove the battery.
4.2. Reading Temperatures
The large LCD display shows three temperature readings simultaneously:
- Тренутна температура: The real-time temperature measured by the probe.
- Минимална температура (MIN): Најнижа температура забележена од последњег ресетовања.
- Максимална температура (MAX): Највиша температура забележена од последњег ресетовања.
4.3. Switching Temperature Units (°F/°C)
Притисните тастер °Ф/°Ц 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 ЦЛЕАР button. The display will show the current temperature for MIN and MAX until new minimum and maximum values are recorded.
4.5. Подешавање аларма
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.
- Притисните тастер СЕТ дугме за улазак у режим подешавања аларма.
- Користите UP и ДОВН arrow buttons to adjust the desired high temperature alarm limit.
- Притисните СЕТ again to confirm the high limit and proceed to set the low temperature alarm limit.
- Користите UP и ДОВН arrow buttons to adjust the desired low temperature alarm limit.
- Притисните СЕТ a third time to exit alarm setting mode and save the settings.
- To enable or disable the alarm, press the АЛАРМ УКЉУЧЕН / ИСКЉУЧЕН дугме. Икона аларма ће се обично појавити на екрану када је аларм активан.
- To silence a sounding alarm, press any button. The alarm will reactivate if the temperature remains outside the set limits.
5. Одржавање
5.1. Чишћење
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 casinг или приказ.
- Ensure the main unit does not get wet, as it is not waterproof. The probe is submersible.
5.2. Замена батерије
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.
