1. Taw qhia
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.
Cov yam ntxwv tseem ceeb:
- 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.

- Tshem lub roj teeb lub hau npog.
- Insert the supplied AAA alkaline battery, ensuring correct polarity (+/-).
- Hloov lub roj teeb lub hau npog kom ruaj ntseg.
3.2. Kev Tso Chaw Soj Ntsuam
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. Mounting lub Main Unit
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.

4.1. Fais fab / Off
The unit powers on automatically upon battery installation. There is no dedicated power button. To turn off, remove the battery.
4.2. Kev nyeem ntawv kub
The large LCD display shows three temperature readings simultaneously:
- Tam sim no kub: 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. Switching Temperature Units (°F/°C)
Nias lub ° 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 TSHIAB button. The display will show the current temperature for MIN and MAX until new minimum and maximum values are recorded.
4.5. Teem Lub Ceeb Toom
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.
- Nias lub SET khawm kom nkag mus rau lub tswb teeb hom.
- Siv cov UP thiab POM arrow buttons to adjust the desired high temperature alarm limit.
- Xovxwm SET again to confirm the high limit and proceed to set the low temperature alarm limit.
- Siv cov UP thiab POM arrow buttons to adjust the desired low temperature alarm limit.
- Xovxwm SET a third time to exit alarm setting mode and save the settings.
- To enable or disable the alarm, press the ALARM 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. Kev tu
5.1. Kev ntxuav
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 casing lub tso saib.
- Ensure the main unit does not get wet, as it is not waterproof. The probe is submersible.
5.2. Hloov roj teeb
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.
