Wind speed, rain and atmospheric pressure
1. In normal display mode, press and hold in [ MODE/SET ] and [ MAX/MIN/ALARM ]
at thesame time for about 5 seconds to enter thecalibrationmode. Thevalue for
thewind speed calibration factor will begin to flash (default=1).
2. Adjust thefactor to avalue in therange0.75–1.25 where:
calibrated wind speed = calibration factor x measured windspeed.
3. Press [ MODE/SET ] once more to adjust thevalue for theamount of rainfall.
Thevalue for therainfall calibration factor will begin to flash (default=1).
4. Adjust thefactor to avalue in therange0.75–1.25 where:
calibrated rainfall = calibration factor x measured rainfall.
5. Press [ MODE/SET ] once more to adjust thevalue for absolute atmospheric
pressure. Theabsolute atmospheric pressure reading will start toflash.
6. Adjust thevalue to your referencevalue. Thevalue can be adjusted in
increments of0.1hPa.
7. Press [ MODE/SET ] once more to adjust thevalue for relative atmospheric
pressure. Therelative atmospheric pressure reading will start toflash.
8. Adjust thevalue to your referencevalue. Thevalue can be adjusted in
increments of0.1hPa.
Installation
Information
We recommend that you familiarise yourself with theindoor and outdoor units before
you install them in their working locations. Thiswill allow you to calibrate thesensors
and test theoperation of theweather station.
Choosing a location
Things to consider before choosing where to install theoutdoor unit:
• The rain sensor should be cleaned every 3 months and thebatteries should be
replaced everyyear. Makesure that theoutdoor unit is mounted in anaccessible
location.
• Make sure that theoperation of theoutdoor unit is not hindered by nearby
structures such as trees and buildings. Arule of thumb is to install it at adistance
of at least four times theheight of nearby obstacles. E.g. ifanearby building is 6 m
in height, theoutdoor unit should be installed 4×6= 24 m away from thebuilding.
• Avoid radiant heat from surrounding buildings, roofs, etc.
• Test theoperation of theoutdoor unit in theintended location before installingit.
Therange can also be affected by thetype of obstacles located between
theindoor unit and theoutdoor unit (e.g. aconcrete wall will interfere with
thesignal more than aplasterboard wall).
• Other wireless equipment using thesame frequency band (433 MHz) can reduce
thetransmissionrange.
