WTH600 - WIRELESS WEATHER STATION
WITH WIRELESS TRANSMITTER SENSOR
1. INTRODUCTION
Thank you for selecting the Extech WTH600 Wireless Weather Station with 5-in-1 wireless sensor.
The sensor includes a self-emptying rain collector for measuring rainfall, an anemometer for wind
velocity, a wind vane for wind direction, a temperature sensor, and a relative humidity sensor. The
WTH600 comes fully assembled and calibrated for convenience. The sensor transmits data up to
492 ft. (150m), line of sight, to the main display unit via low power radio frequency. The main unit
displays all of the weather data received from the sensor and the user can recall stored weather
data (24-periods). The WTH600 is a powerful and unique personal weather station that, with
proper use, will provide years of reliable service.
FEATURES
HI/LO Alarms alert the user when programmed weather limits are exceeded
Barometric pressure is computed and helps forecast the weather and possible storms
Min/Max feature includes date/time stamp
View Rainfall rate and daily/weekly/monthly amounts
Wind-speed levels are shown expressed in Beaufort scale
Wind-chill, Heat Index, Dew point, and Comfort level are computed and displayed

Wireless Sensor
The wireless sensor measures wind-speed, wind-direction, rainfall, temperature and humidity. The
sensor ships fully assembled and calibrated for easy installation.
Battery and installation
Unscrew the battery door at bottom of unit and insert the batteries
according to the “+/-”polarity indicated. Screw the battery door
compartment on tightly. Note:
1. Align the watertight O-ring to ensure water-resistance.
2. The red LED will begin flashing every 12 seconds.

Install the wireless sensor in an open location with no obstructions above and around the sensor
for accurate rain and wind measurement. Install the sensor with the smaller end facing to the
North (proper orientation of the wind direction vane). Secure the mounting stand and bracket
(included) to a post or pole, and allow a minimum distance of 1.5m off the ground.
Mounting guidelines
1. Install the wireless sensor at least 1.5m off the ground for accurate wind measurements.
2. Choose an open area within 150 meters from the Main Unit.
3. Install the wireless sensor as level as possible to achieve accurate rain and wind measurements.
The included leveling device ensures a level installation.
4. Mount the wireless sensor with the wind meter end pointing to the North.
5. Pole mount shown below left and railing mount below right.
