WTH600 - WIRELESS WEATHER STATION
WITH WIRELESS TRANSMITTER SENSOR
FOR USE IN NORTH AMERICA ONLY
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

- Page 8 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.
- Page 9 5. MAIN UNIT OPERATION, BATTERIES, MOUNTING Battery Installation and Mounting The WTH600 can be placed on a desktop or can be wall mounted for easy viewing. 1. Remove the battery door of the main unit. 2. Insert three ‘AA’ batteries according to the “+/-” polarity marks on the battery compartment. 3.
- Page 10 2. Always place the unit away from interfering sources such as TV monitors, computers, etc. 3. Avoid placing the unit on or next to metal plates. 4. Enclosed areas such as airports, basements, or factories are not recommended. Setting the Date and Time The unit automatically sets itself accordingly to the Radio Controlled Clock signal it receives.
- Page 11 Set the Alarm Clock 1. Press and hold [ALARM] for 2 seconds to enter alarm setting mode. HOUR will begin to flash. 2. Use [UP]/[DOWN] buttons to adjust HOUR, and press [ALARM] button to proceed to MINUTE. 3. Repeat step 2 above to set MINUTE, then press [ALARM] button to exit. Note: Pressing the [ALARM] button twice when alarm time is displayed will activate the temperature-adjusted pre-alarm (alarm will sound 30 minutes earlier if it detects outside temperature is below 26°F (-3°C)).
- Page 12 3. The built-in barometer detects the environmental absolute atmospheric pressure changes. Based on the data collected, it can predict weather conditions for the next 12 hours. The weather indicators will change according to the detected absolute atmospheric pressure after 1 hour. 4.
- Page 13 Select the Wind Display mode Press [WIND] button to toggle between: • AVERAGE The AVERAGE wind speed will display the average of all wind speed numbers recorded in the previous 30 seconds • GUST The GUST wind speed will display the highest wind speed recorded from last reading The wind level provides a quick reference and is indicated by a series of text icons: Select Wind Speed Units 1.
- Page 14 Strong breeze 39–49 km/h Large branches in motion. Whistling heard in 25–30 mph overhead wires. Umbrella use becomes difficult. Empty plastic bins tip over. 22–27 knots 10.8–13.8 m/s High wind 50–61 km/h Whole trees in motion. Effort needed to walk against the wind.
- Page 15 View Dew point (Indoor) Press the [INDEX] button repeatedly until DEWPOINT appears. Note: The dew point is the temperature below which the water vapor in air, at a constant barometric pressure, condenses into liquid water at the same rate at which it evaporates. ‘Dew’ is the term used to describe the condensed water that forms on a solid surface.
- Page 16 Set the HI / LO alert 1. Press the [ALERT] button to select the desired display field. 2. Use [UP] / [DOWN] buttons to adjust the settings. 3. Press [ALERT] button to confirm and continue to the next setting. Enable/disable the HI / LO Alarm Alert 1.
- Page 17 Note: 1. Comfort indication can vary at the same temperature, depending on the humidity. 2. There is no comfort Indication when temperature is below 32°F (0°C) or above 140°F (60°C). 17. CLEARING STRAY READINGS During installation of the wireless sensor, the sensors are typically triggered which results in erroneous rainfall and wind measurements.
