1. Johdanto
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.
Tärkeimmät ominaisuudet:
- 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. Asennus
3.1. Akun asennus
- Paikanna paristolokero laitteen takana.
- Irrota paristolokeron kansi.
- Insert the supplied AAA alkaline battery, ensuring correct polarity (+/-).
- Aseta paristolokeron kansi kunnolla takaisin paikalleen.
3.2. Mittapään sijoitus
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. Pääyksikön asentaminen
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. Käyttöohjeet
4.1. Virta päälle/pois
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:
- Nykyinen lämpötila: The real-time temperature measured by the probe.
- Minimum Temperature (MIN): The lowest temperature recorded since the last reset.
- Maximum Temperature (MAX): The highest temperature recorded since the last reset.
4.3. Lämpötilayksiköiden vaihtaminen (°F/°C)
Paina °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 TYHJENNÄ button. The display will show the current temperature for MIN and MAX until new minimum and maximum values are recorded.
4.5. Hälytysten asettaminen
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.
- Paina SARJA -painiketta siirtyäksesi hälytyksen asetustilaan.
- Käytä UP ja ALAS arrow buttons to adjust the desired high temperature alarm limit.
- Paina SARJA again to confirm the high limit and proceed to set the low temperature alarm limit.
- Käytä UP ja ALAS arrow buttons to adjust the desired low temperature alarm limit.
- Paina SARJA a third time to exit alarm setting mode and save the settings.
- To enable or disable the alarm, press the HÄLYTYS 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. Huolto
5.1. Puhdistus
Regular cleaning helps maintain the accuracy and longevity of your thermometer.
- Wipe the main unit and probe with a damp liinaa. Tarvittaessa voidaan käyttää mietoa saippualiuosta.
- Do not use abrasive cleaners or solvents, as these may damage the plastic casing tai näyttö.
- Ensure the main unit does not get wet, as it is not waterproof. The probe is submersible.
5.2. Pariston vaihto
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. Anturin hoito
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.
