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

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. Points to NORTH 1.5 meter off the ground Mounting guidelines 1. Install the wireless sensor at least 1.

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. Replace the battery door. 4. Once the batteries are inserted all of the LCD segments will be shown briefly before entering the radio-controlled time reception mode. 5.
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. To set the clock/calendar manually, first disable the reception by holding the RCC button for 8 seconds. Manually Setting the Clock and Time Zone 1.

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)). 6.

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. The relative atmospheric pressure is based on the sea level, but it will change with the absolute atmospheric pressure changes after operating the clock for 1 hour. Select the Measurement Units for the Barometer 1.

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. The dew point temperature is calculated from the indoor temperature/humidity measured at the Main Unit. 12.

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. Press the [ALERT] button to select the desired display field. 2. Use [ALARM] to turn the alert on or off. 3. Press [ALERT] to continue to the next setting. Note: 1. The unit will automatically exit setting mode in 5 seconds if no button is pressed. 2.

Too cold Comfortable Too hot 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.
