Dew Point temperature
Dew point is the saturation point of the air, or the temperature to which the air has to cool in order to
create condensation (100% humidity). Dew Point Temperature reflects the point at which
condensation and evaporation are equal. Dew Point Temperature is the accurate measure of the
quantity of water vapor in the air.
Dew Point Temperature does not change with air temperature changes. It only changes with moisture
content changes with barometric pressure stable.
Note:
Dew Point is lower than the actual temperature.
Note:
A Frost Point occurs when the Dew Point Temperature is below freezing.
MIN/MAX temperature readings
View:
With the temperature and humidity icon flashing, press the MEMORY button to recall a current
temperature and humidity, minimum temperature and humidity or maximum temperature and humidity
at the remote location.
Reset:
Hold the MEMORY button for five seconds to clear all MIN/MAX readings.
Wind Transmitter
The wind sensor reads directly to the weather station. It is not dependent on the thermohygro sensor
for signal reception.
2-AA batteries power the wind sensor.
Cups spinning slow or not spinning
Check for debris or ice in cups.
Be sure cups are below mast holder.
Check
mounting
location. Look for obstructions that prevent the wind from reaching the transmitter.
The mast should not be more than 1¼ inch thick.
The wind transmitter needs to be 4 to 6ft above the highest point on the roof to read accurately.
A 50-foot clearance in all directions is best.
Push up firmly on the center of the cups to reseat them. Occasionally they drop a bit.
Cups are replaceable.
Replace wind cups and set wind direction
Replace wind cups
The cups attach with a single screw through the side of the wind cups.
Loosen the screw.
Gently and firmly pull the cups straight down to remove.
Notice the metal stem where the cups attach.
There is a flat spot on one side of the stem. It is important that the screw be aligned with the flat spot
to prevent them from dropping in high winds.
Install replacement wind cups aligning the screw with the flat spot on the stem.
Tighten the screw.
Test to assure the wind cups are securely mounted on the anemometer shaft and spin freely
Note:
If wind speed shows 0.00 but direction works, check that the wind cups did not drop.
Set Wind Direction
Check that all the sensor readings are received by the weather station.
Remove the battery cover (not the batteries) from the wind sensor.
Manually point the wind direction vane to the North (use a compass or map if necessary).
