3.2 Temperature and Humidity Readings

The display shows current temperature and humidity for each channel. Trend arrows indicate whether the temperature or humidity is rising, falling, or remaining stable.

3.3 Max/Min Records

The device records the maximum and minimum temperature and humidity values over the last 24 hours. Press the 'MEM' button to cycle through current, maximum, and minimum readings.

3.4 Comfort Indicator

A face icon on the display indicates the comfort level based on current temperature and humidity:

• Dry: Humidity < 40%
• Comfort: 40% ≤ Humidity ≤ 70% and 20℃ ≤ Temperature ≤ 28℃
• Wet: Humidity > 70%

3.5 Unit Selection (°C/°F)

Press the '℃/℉' button to switch between Celsius and Fahrenheit temperature units.

3.6 Temperature and Humidity Alerts

You can set high and low alert values for temperature and humidity for each channel. When the readings exceed or fall below these preset values, an audible alarm will sound, and the corresponding HI AL or LO AL symbol will appear on the screen.

4. Maintenance

4.1 Battery Replacement

Replace batteries in the main unit and sensors when the low battery indicator appears on the display. Always replace all batteries in a unit at the same time with new ones of the same type.

4.2 Cleaning

Wipe the device and sensors with a soft, damp cloth. Do not use abrasive cleaners or immerse the units in water.

5. Troubleshooting

• No display on main unit: Check battery installation and polarity. Ensure batteries are not depleted. If using USB power, check the cable connection.
• Remote sensor not displaying data:
  • Ensure sensor batteries are correctly installed and not depleted.
  • Verify the sensor channel switch matches the selected channel on the main unit.
  • Move the sensor closer to the main unit to check if it's out of range.
  • Avoid major metal obstructions between the sensor and the main unit.
• Inaccurate readings:
  • Ensure sensors are not exposed to direct sunlight, heat sources, or extreme drafts.
  • Allow the units to stabilize for 15-30 minutes after initial setup or battery replacement.
• Alerts not sounding: Check that alert values are correctly set and the alert function is enabled.
