2. Press MODE until is displayed.
3. Tilt the tipping funnel on the rain gauge several times
and verify a numerical reading on the base station.
TIP If no reading is displayed for a sensor, press the
SEARCH button on the base station to initiate a wireless
sensor search.
MOUNTING / PLACING OF SENSORS
WIND SENSOR
NOTE The sensor should be positioned in an open area
away from trees or other obstructions.
ab
Secure the sensor connector in the desired location:
a. Align the back of the sensor connector to an existing
pole. Secure in place by inserting the ends of the
U-bolt into the holes on the sensor connector and
securing it with washers and bolts.
OR
b. Insert 4 type A screws into the holes of the sensor
connector. Screw firmly into place, i.e., fence.
Slide wind vane onto the smaller end of the sensor
connector.
IMPORTANT Ensure that the wind sensor is pointing
North to enable it to record accurate readings.
TEMPERATURE / HUMIDITY SENSOR
1.5 m (5 ft)
TIP Ideal placements for the sensor would be in any
location on the exterior of the home at a height of not
more than 1.5 m (5 ft) and which can shield it from direct
sunlight or wet conditions for an accurate reading.
Secure the sensor in the desired location using the wall
mount bracket or table stand.
RAIN GAUGE
The base station and rain gauge should be positioned
within an effective range: about 100 meters (328 feet)
in an open area.
The rain gauge should be mounted horizontally about 1
meter (3 feet) from the ground in an open area away from
trees or other obstructions to allow rain to fall naturally
for an accurate reading.

6
EN
To ensure a level plane:
Put a few drops of water on the cross at the base of the
funnel to check the horizontal level.
1
23
4
Water will pool to the center of the cross when the rain
gauge is level.
If water remains on 1-4, the gauge is not horizontal.
If necessary, adjust the level using the screw.
NOTE For best results, ensure the base is horizontal to
allow maximum drainage of any collected rain.
TIP Press RESET button on base station to erase all
testing data.
CLOCK RECEPTION

UVI / BAROMETER / RAINFALL
The weather station works with one UV sensor and
one rain gauge. The station is capable of storing and
displaying the hourly history data for the last 10 hours
of UV index, and 24 hours of rainfall and barometric
pressure readings.
UVI BAROMETER RAINFALL
The bar chart display shows the current and historical
data for the UV index, barometric pressure and rainfall
readings.
NOTE The number shown in the horizontal axis (Hr)
indicates how long ago each measurement was taken (e.g.
3 hours ago, 6 hours ago, etc.). The bar represents the
measurement taken for that specific 1 hour period. E.g., if it
is 10:30 pm now, the bar plotted directly above -1 shows the
reading recorded from 9 to 10 pm and -6 shows the reading
recorded earlier in the evening, between 4pm-5pm.
To view the UV / Barometer / Rainfall readings:
1. Press SELECT to navigate to the UV / Barometer /
Rainfall Area. will show next to the Area.
2. Press MODE to toggle between UVI / Barometer
/ Rainfall readings. The corresponding icon will

switch between:
• Barometer: Millimeters of mercury (mmHg), inches
of mercury (inHg), millibars per hectopascal (mb).
• Rainfall: Millimeters (mm), inches (in), recorded for
that hour.
NOTE As the purpose of the bar graph is only to provide
a quick comparison between the records of the past 24
hours, the vertical axis cannot convert from inches to mm.
Therefore, changing the measurement unit will have no
effect on the bar graph display.
UV INDEX
The UV index levels are as follows:
UV INDEX DANGER LEVEL ICON
0-2 Low
3-5 Moderate
6-7 High
