DIRECTION CALIBRATION

Before pairing a wind sensor, make sure the head of the wind vane of that sensor
point to the north while pressing KEY for 2 seconds in the transmitter box to calibrate
the direction. If the calibration is successful, red light flashes once. You can use a
compass to look for an accurate direction of north if necessary.
However, if you are the user in North America, there are already 15°(degree)
variations existing between the true north and a compass reading of north. You
can consult your local observatory about this issue.
If it is difficult to control the wind vane after installation, you can calibrate through
setting on main unit.
1. Make a compass approach to the wind vane.
2. Calculate the angle between the current direction
and the north direction.
3. Press wind area to activate.
4. Press and hold , and then
press or to calibrate
the angle value.
5. Press again to confirm setting.
For example, inputting the angle value that you
want to set as north. If current direction is 25
degree and you want to set it as north, then you
input 25 degree in the calibration mode. Once
you return to the idol mode, the direction reading
displays 0 degree, which is the north.
NOTE You need to calibrate the wind sensor again if you want to relocate the sensor.

WIND SPEED / DIRECTION

To select wind display mode:
Press wind area to toggle between:
GUST (Gust)
•
AVG (Average)

To select wind speed unit:
Press to switch among:
Knots (knots)

NOTE The wind chill factor is based on the combined effects of temperature and
wind speed. Displayed wind chill is calculated solely from channel 1 thermometer
and humidity sensor.

BAROMETRIC PRESSURE

The altitude reflects distance from sea level at your position.
To set the altitude level compensation for the barometric readings:
1. Press area to activate.
displays at the below of the screen.
2. Press the area until ALT displays on the screen. You are in altitude mode.
3. Press and hold on the tool bar.
4. Press or
altitude unit between M (Meter) and FEET (Feet) while editing.
5. Press to confirm or touch panel area (except tool bar/barometer
area) to confirm.
6. After setting altitude, the new altitude setting will not be effective immediately.
The ALT icon flashes and stops flashing until the next pressure sampling. The
new altitude setting takes effect on the new pressure sampling.
NOTE When altitude is set to 0 meter, the pressure reading is the local pressure.
If the altitude is set to the current location, the new pressure reading is an offset
pressure to the sea level.
To select the measurement unit for the barometer:
1. Press barometer area to toggle between altitude and current barometer.
2. Press to select inHg (inches of mercury) / mmHg (millimetres of
mercury) / mb (millibars per hectopascal) / hPa.
To view pressure trend:
The barometric pressure trend icons are based on recent sensor readings.
The trend lines are shown next to the pressure readings. The trend is shown
as follows:

RAINFALL

To select rainfall display mode:
Press rain area to toggle between:
THIS HOUR (Hourly rainfall)
•
RATE (Rain rate)
•
• ACCUM (Accumulated rainfall)
• PAST 24 hrs (Rainfall recorded in the past 24 hours)
To select the measurement unit for the rainfall:
Press to select between mm (millimeter) and in (inch).
To select the measurement unit for the rainfall rate:
Press to select between in/hr (inch per hour) and mm/hr (millimeter
per hour).

ACCUMULATED RAINFALL

To display accumulated rainfall:
Press rain area repeatedly until ACCUM display. (SINCE displays in the
clock area that displays the start date / time of rainfall recording simultaneously).
To reset SINCE time:
Press and hold MEM to set current time as start of accumulated rainfall records.
The rainfall record is cleared and reset to 0.
