1. Einleitung
This manual provides comprehensive instructions for the proper setup, operation, and maintenance of your VWR 10500-584 Traceable Refrigerator/Freezer Ultra Thermometer. This device is designed to accurately monitor temperatures in refrigerators and freezers, displaying current, minimum, and maximum readings simultaneously. It is engineered to meet stringent requirements for critical temperature monitoring, including CDC guidelines for vaccine storage.
2. Produktmerkmale
- Dreifachanzeige: Simultaneously shows current, minimum, and maximum temperatures.
- Großer Temperaturbereich: Misst von -50 °C bis 70 °C (-58 °F bis 158 °F).
- Hohe Auflösung: 0.1° resolution for precise readings.
- Ultra Accuracy: ±0.5°C accuracy between -30°C and 50°C; otherwise ±1°C.
- CDC Compliance: Designed to meet current CDC requirements for vaccine storage and monitoring.
- Sondenauswahl: Features a switch for selecting between two probes (if applicable, based on image).
- Memory Clear Function: Button to reset minimum and maximum temperature records.
3. Einrichtung
Follow these steps to prepare your thermometer for use:
- Einlegen der Batterie: Open the battery compartment (typically on the back) and insert the required batteries, observing correct polarity.
- Platzierung der Sonde: Connect the temperature probe(s) to the designated ports. Place the probe(s) in the desired monitoring location within the refrigerator or freezer. Ensure the probe cable is not pinched or damaged by the door seal.
- Erstes Einschalten: The device should power on automatically once batteries are installed. Verify the display shows temperature readings.
- Einheitenauswahl: If applicable, select the desired temperature unit (°C or °F) using the appropriate button (often the 'MODE' button or a dedicated switch).

4. Bedienungsanleitung
Understanding the display and controls:
- Aktuelle Temperatur: The largest number on the display indicates the real-time temperature reading from the selected probe.
- Minimum (MIN) Temperature: Shows the lowest temperature recorded since the last memory clear.
- Maximum (MAX) Temperature: Shows the highest temperature recorded since the last memory clear.
- MEMORY CLEAR Button: Press this button to reset the recorded minimum and maximum temperatures. The current temperature will then become the initial MIN and MAX values until new extremes are reached.
- MODE-Taste: This button typically cycles through display modes or switches between Celsius and Fahrenheit units. Refer to the specific device markings for its exact function.
- PROBE Switch (1/2): If your model has two probes, use this switch to select which probe's readings are displayed as the current temperature. The MIN/MAX values will correspond to the currently selected probe.
5. Wartung
- Reinigung: Wipe the thermometer unit and probes with a damp cloth. Do not immerse the main unit in water. Avoid using abrasive cleaners or solvents.
- Batteriewechsel: When the display becomes dim or the low battery indicator appears, replace the batteries promptly. Use the specified battery type.
- Sondenpflege: Handle probes carefully. Avoid bending or kinking the probe cables excessively. Ensure probe connections are secure.
- Lagerung: When not in use for extended periods, remove batteries and store the thermometer in a cool, dry place.
6. Fehlerbehebung
| Problem | Mögliche Ursache | Lösung |
|---|---|---|
| Keine oder nur schwache Anzeige | Leere oder schwache Batterien; falsche Batterieinstallation. | Ersetzen Sie die Batterien durch neue und achten Sie dabei auf die richtige Polarität. |
| Ungenaue Temperaturwerte | Probe not properly connected; damaged probe; external interference. | Check probe connection. Inspect probe for damage. Ensure probe is correctly positioned. |
| MIN/MAX values not resetting | 'MEMORY CLEAR' button not pressed firmly or device malfunction. | Press the 'MEMORY CLEAR' button firmly. If issue persists, contact support. |
