1. Introduction
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.
Caractéristiques principales :
- 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. Contenu du colis
Vérifiez que tous les éléments énumérés ci-dessous sont présents et en bon état :
- TRACEABLE Jumbo Calibrated Digital Fridge/Freezer Thermometer (Model AO-94460-73)
- 1 5-mL Bottle Probe (submersible)
- Certificat d'étalonnage traçable NIST avec données
- Hook-and-loop strips for mounting
- Magnetic strips for mounting
- Une pile alcaline AAA
3. Installation
3.1. Installation de la batterie
- Localisez le compartiment à piles à l’arrière de l’appareil.
- Retirez le couvercle du compartiment à piles.
- Insert the supplied AAA alkaline battery, ensuring correct polarity (+/-).
- Replacez soigneusement le couvercle du compartiment à piles.
3.2. Placement de la sonde
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. Montage de l'unité principale
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).
- Bandes magnétiques : 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. Mode d'emploi
4.1. Marche/Arrêt
The unit powers on automatically upon battery installation. There is no dedicated power button. To turn off, remove the battery.
4.2. Lecture des températures
The large LCD display shows three temperature readings simultaneously:
- Température actuelle : The real-time temperature measured by the probe.
- Température minimale (MIN) : La température la plus basse enregistrée depuis la dernière réinitialisation.
- Température maximale (MAX) : La température la plus élevée enregistrée depuis la dernière réinitialisation.
4.3. Switching Temperature Units (°F/°C)
Appuyez sur le °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 CLAIR button. The display will show the current temperature for MIN and MAX until new minimum and maximum values are recorded.
4.5. Réglage des alarmes
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.
- Appuyez sur le ENSEMBLE pour accéder au mode de réglage de l'alarme.
- Utilisez le UP et VERS LE BAS arrow buttons to adjust the desired high temperature alarm limit.
- Presse ENSEMBLE again to confirm the high limit and proceed to set the low temperature alarm limit.
- Utilisez le UP et VERS LE BAS arrow buttons to adjust the desired low temperature alarm limit.
- Presse ENSEMBLE a third time to exit alarm setting mode and save the settings.
- To enable or disable the alarm, press the ALARME 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. Entretien
5.1. Nettoyage
Regular cleaning helps maintain the accuracy and longevity of your thermometer.
- Essuyez l'unité principale et la sonde avec un produit nettoyant pour appareils électroniques.amp Un chiffon. Une solution de savon doux peut être utilisée si nécessaire.
- Do not use abrasive cleaners or solvents, as these may damage the plastic casing ou affichage.
- Ensure the main unit does not get wet, as it is not waterproof. The probe is submersible.
5.2. Remplacement de la batterie
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. Entretien de la sonde
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. Dépannage
If your thermometer is not functioning as expected, please refer to the following common issues and solutions:
| Problème | Cause possible | Solution |
|---|---|---|
| Aucun affichage ou affichage faible | Batterie morte ou mal installée | Remplacez la pile AAA en respectant la polarité. |
| Lectures de température incorrectes | Probe not properly placed or damaged | Ensure the probe is fully immersed or correctly positioned. Inspect the probe and cable for damage. |
| L'alarme ne sonne pas | Alarm disabled or settings incorrect | Verify that the alarm is enabled (check for alarm icon) and that high/low limits are set appropriately. |
| MIN/MAX values not resetting | CLEAR button not pressed | Appuyez sur le CLAIR button to reset the memory. |
