This image demonstrates different ways to position the wireless sensors within a refrigerator or freezer.
The main display unit can be placed on a countertop using its integrated stand or mounted on a metallic surface using its rear magnets.
Operating Instructions
Display Overview
The main display unit shows current temperatures for two channels, along with max/min records and status icons.
The display shows temperatures for two channels (CH1 and CH2), along with their respective maximum (MAX) and minimum (MIN) recorded temperatures. Signal strength indicators for each sensor and battery level indicators are also present.
1. Temperature Unit Selection (℃/℉)
On the back of the main display unit, locate the small "C/F" button. Press this button to toggle between Celsius (℃) and Fahrenheit (℉) temperature units.
This image highlights the C/F switch on the back of the main unit and other key features.
2. Max/Min Temperature Records
The display shows the maximum and minimum temperatures recorded over a 24-hour period. To view historical max/min records (since the last reset or power cycle), briefly press the "UP" or "DOWN" buttons on the main unit. To reset the max/min records, press and hold the "CLEAR" button (usually indicated by a trash can icon or similar) for a few seconds.
3. 2-Channel Alarm Setting
The thermometer allows you to set high and low temperature alarms for each channel.
- Briefly press the channel button (e.g., "CH1" or "CH2" button, or a general "Channel" button) to enter alarm setting mode for that channel.
- Use the "UP" and "DOWN" buttons to adjust the desired high and low temperature thresholds.
- Press and hold the "Alarm" button (often indicated by a bell icon) to toggle the alarm function ON or OFF for the selected channel.
- An audible alarm will sound if the temperature exceeds the set high threshold or falls below the set low threshold.
This image illustrates the alarm function, showing how to set upper and lower temperature limits for alerts.
4. Backlight Function
To illuminate the display for easier reading in low-light conditions, touch the light bulb icon on the top of the main unit. The backlight will activate for approximately 10 seconds.
Key Features
- Dual Wireless Sensors: Monitor two separate locations simultaneously.
- Wide Temperature Range: Measures temperatures from -40°C to 37°C (-40°F to 98.6°F).
- Max/Min Record: Tracks the highest and lowest temperatures recorded over 24 hours or historically.
- Audible Alarms: Alerts you when temperatures exceed or fall below preset thresholds.
- Low Battery Indicator: Displays icons for low battery on both the main unit and sensors.
- Backlight: Provides temporary illumination for clear reading in dim environments.
- Versatile Placement: Main unit features a stand and magnets; sensors can be hung, magnetically attached, or secured with suction cups.
The thermometer is suitable for various applications, including refrigerators, freezers, and wine coolers.
Maintenance
- Cleaning: Wipe the main unit and sensors with a soft, damp cloth. Do not use abrasive cleaners or immerse the devices in water.
- Battery Replacement: Replace batteries promptly when the low battery indicator appears on the display. Refer to the "Battery Installation" section for instructions.
- Storage: If storing the device for an extended period, remove all batteries to prevent leakage. Store in a cool, dry place.
Low Battery Indicator
The display unit features separate low battery indicators for the main unit and each sensor. When a battery icon appears, it indicates that the corresponding battery needs replacement.
This image highlights the low battery indicators for the sensors and the main display unit.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display on main unit. | Batteries are dead or incorrectly installed. | Check battery polarity and replace with fresh AAA batteries. |
| Sensor reading "---" or inaccurate. | Sensor batteries are dead, sensor is out of range, or interference. | Replace sensor CR2032 batteries. Move sensor closer to the main unit. Avoid placing near large metal objects or electronics that may cause interference. |
| Alarm not sounding. | Alarm function is off or thresholds are set too wide. | Ensure the alarm is enabled for the desired channel. Adjust alarm thresholds to appropriate levels. |
| Backlight not working. | Main unit batteries are low or depleted. | Replace main unit AAA batteries. |
