1. Einleitung
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.
Hauptmerkmale:
- 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. Einrichtung
3.1. Einlegen der Batterie
- Suchen Sie das Batteriefach auf der Rückseite des Geräts.
- Entfernen Sie die Abdeckung des Batteriefachs.
- Insert the supplied AAA alkaline battery, ensuring correct polarity (+/-).
- Bringen Sie den Batteriefachdeckel wieder fest an.
3.2. Sondenplatzierung
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 der Haupteinheit
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).
- Magnetstreifen: 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. Bedienungsanleitung
4.1. Ein-/Ausschalten
The unit powers on automatically upon battery installation. There is no dedicated power button. To turn off, remove the battery.
4.2. Temperaturmessung
The large LCD display shows three temperature readings simultaneously:
- Aktuelle Temperatur: The real-time temperature measured by the probe.
- Minimum Temperature (MIN): Die niedrigste seit dem letzten Reset gemessene Temperatur.
- Maximum Temperature (MAX): Die höchste seit dem letzten Reset gemessene Temperatur.
4.3. Umschalten der Temperatureinheiten (°F/°C)
Drücken Sie die °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 KLAR button. The display will show the current temperature for MIN and MAX until new minimum and maximum values are recorded.
4.5. Alarme einstellen
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.
- Drücken Sie die SATZ Taste, um in den Alarmeinstellungsmodus zu wechseln.
- Verwenden Sie die UP Und RUNTER arrow buttons to adjust the desired high temperature alarm limit.
- Drücken SATZ again to confirm the high limit and proceed to set the low temperature alarm limit.
- Verwenden Sie die UP Und RUNTER arrow buttons to adjust the desired low temperature alarm limit.
- Drücken SATZ a third time to exit alarm setting mode and save the settings.
- To enable or disable the alarm, press the ALARM EIN / AUS Taste. Normalerweise erscheint ein Alarmsymbol auf dem Display, wenn der Alarm aktiv ist.
- To silence a sounding alarm, press any button. The alarm will reactivate if the temperature remains outside the set limits.
5. Wartung
5.1. Reinigung
Regular cleaning helps maintain the accuracy and longevity of your thermometer.
- Wipe the main unit and probe with a damp Ein Tuch. Bei Bedarf kann eine milde Seifenlösung verwendet werden.
- Do not use abrasive cleaners or solvents, as these may damage the plastic casing oder Anzeige.
- Ensure the main unit does not get wet, as it is not waterproof. The probe is submersible.
5.2. Batteriewechsel
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. Sondenpflege
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. Fehlerbehebung
If your thermometer is not functioning as expected, please refer to the following common issues and solutions:
| Problem | Mögliche Ursache | Lösung |
|---|---|---|
| Keine oder nur schwache Anzeige | Leere oder falsch eingesetzte Batterie | Tauschen Sie die AAA-Batterie aus und achten Sie dabei auf die richtige Polarität. |
| Falsche Temperaturwerte | Probe not properly placed or damaged | Ensure the probe is fully immersed or correctly positioned. Inspect the probe and cable for damage. |
| Der Alarm ertönt nicht | 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 | Drücken Sie die KLAR button to reset the memory. |
