6. WEATHER FORECAST

The WTH600-E includes a sensitive pressure sensor that predicts weather for the next 12 ~ 24
hours within a 19-31 miles (30 to 50km) radius.
Note:

1. The accuracy of a general pressure-based weather forecast is about 70% to 75%.

2. The weather forecast does not necessarily reflect the current weather conditions.

er forecast is not based on atmospheric pressure; it is based on outdoor
temperature. When the outdoor temperature is below 26°F (-3°C)
will be displayed on the LCD.

7. BAROMETRIC / ATMOSPHERIC PRESSURE

Atmospheric Pressure is the pressure at any location of the Earth caused by the weight of the
column of air above it. One atmospheric pressure refers to the average pressure and gradually
decreases as altitude increases. Meteorologists use barometers to measure atmospheric pressure.
Since variation in atmospheric pressure is greatly affected by weather, it is possible to forecast the
weather by measuring the changes in pressure.

Select the Display mode

Press and hold the [BARO] button for 2 seconds to toggle between:

ABSOLUTE the absolute atmospheric pressure of your location
RELATIVE the relative atmospheric pressure based on sea level

EU/UK Version 11 WTH600-E-en-GB_v1.0 4/18

Find Quality Products Online at: [e-mail]

www.GlobalTestSupply.com

Set the Relative Atmospheric Pressure

1. Obtain the atmospheric pressure data for the sea level (the relative atmospheric pressure for
your current location) through the local weather service, internet or other channel.

2. Press and hold [BARO]

3. Press [UP] [DOWN] buttons

4. Press [BARO] button pheric pressure digit flashes.

5. Press [UP] [DOWN] buttons to change its value.

6. Press [BARO] button to save and exit the setting mode.
Note:

1. The default relative atmospheric pressure value is 29.91 inHg (1013 hPa), which refers to the
average atmospheric pressure.

2. When you change the relative atmospheric pressure value, the weather indicators will change.

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. Press the [BARO] button to enter the unit setting mode.

2. Use the [BARO] button to change the units to inHg (inches of mercury) / mmHg (millimeter of
mercury) (millibars per hectopascal) /hPa.

3. Press the [BARO] button to confirm.

15. WIRELESS SIGNAL RECEPTION

EU/UK Version 16 WTH600-E-en-GB_v1.0 4/18

Find Quality Products Online at: [e-mail]

www.GlobalTestSupply.com

The sensor transmits data wirelessly over an approximate range of 150m (line of sight).
Occasionally, due to intermittent physical obstructions or other environmental interference, the
signal may weaken or be lost. If the sensor signal is lost completely, please relocate the main unit
or the wireless sensor.

16. TEMPERATURE/HUMIDITY COMFORT LEVELS

Comfort Indication

The comfort pictorial indication is based on indoor air temperature and humidity.

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. After the installation, the user may clear all of the
erroneous data from the Main Unit, without having to reset the clock and re-establish pairing.
Simply press and hold the [HISTORY] button for 10 seconds. This will clear all data.

18. POINTING SENSOR TO THE SOUTH

The outdoor sensor is calibrated to be pointing to North by default. However, in some cases, users
may wish to install the product with the arrow pointing towards the South, especially for those
living in the Southern hemisphere (e.g. Australia, New Zealand).

1. Install the outdoor sensor with its arrow pointing to the South.

2. On the main unit, press and hold [WIND] for 8 seconds until the upper part (Northern
Hemisphere) of the compass lights and starts blinking.

3. Use [UP] / [DOWN] buttons to move to the lower part (Southern Hemisphere).

4. Press the [WIND] button to confirm and exit.
Note: Changing hemispheres will automatically switch the direction of the displayed moon phases.
