13307 Thermo-Hygrometer FAQs
Why is the temperature way off from what I expected?
The temperature display is set to the external probe and you want the internal sensor or vice versa. Press the “Int/Ext” button to correct.
Why is the temperature not changing?
The “Min” or “Max” reading is showing. Press the “Min/Max” button to set the display for real-time.
Why is the Thermo-Hygrometer showing “-.-“ for humidity?
The humidity went above the maximum range or dew point was reached and moisture formed on the sensor. Allow the unit to dry in a low humidity environment until it starts reading again. At very low humidity such as below 13% the unit will stop reading until the humidity rises. If the temperature goes below freezing (0.0°C, 32°F) the humidity will no longer be displayed until the temperature rises above freezing.
How long does it take for the Thermo-Hygrometer to stabilize before getting a stable reading?
It is a good idea to leave the unit in a stable environment for at least 30 minutes to get an accurate reading. This is dependent on the amount or temperature/humidity change and the air flow in the area.
Should I put my 13307 Thermo-Hygrometer in direct sunlight?
If placed in direct sunlight for prolonged periods the LCD display will darken and may not fully recover.
I put my 13307 Thermo-Hygrometer in a freezer and it no longer displays humidity or temperature – what happened?
At around -10°F the LCD will fade until the numbers can no longer be seen. This is inherent to LCD technology and the display will recover when it warms up. Try placing the base unit outside the freezer and the probe only inside.
