Product Usage Instructions

Powering On/Off
To power on the device, press and hold the power button for a few seconds until the display lights up. To power off the device, press and hold the power button again until the display turns off.
Temperature Measurement
To measure the ambient temperature, ensure the device is powered on. Hold the device in your hand or place it in the desired location, making sure it is not exposed to direct sunlight or any other heat sources. The temperature reading will be displayed on the LCD screen.
Humidity Measurement
To measure the humidity, ensure the device is powered on. Hold the device in your hand or place it in the desired location, away from any moisture sources. The humidity reading will be displayed on the LCD screen.
Dew Point Temperature Measurement
The device is capable of measuring the dew point temperature, which indicates the temperature at which air becomes saturated and condensation occurs. To measure the dew point temperature, ensure the device is powered on and follow the same procedure as temperature measurement. The dew point temperature reading will be displayed on the LCD screen.
Wet Bulb Temperature Measurement
The wet bulb temperature is a measurement that takes into account the evaporative cooling effect of water. To measure the wet bulb temperature, ensure the device is powered on and follow the same procedure as temperature measurement. The wet bulb temperature reading will be displayed on the LCD screen.

Frequently Asked Questions (FAQ)

Q: Can this device be used outdoors?
A: Yes, this device can be used outdoors as long as it is within the specified working temperature range of -20°C to 60°C.
Q: How often should I replace the batteries?
A: The device has a low power consumption and the batteries should last for an extended period of time. However, it is recommended to replace the batteries when the display becomes dim or if the device fails to power on.
Q: Can I calibrate the device?
A: This device does not support user calibration. It has been factory calibrated and should provide accurate measurements within the specified accuracy range.
