Wind speed, rain and air pressure
1. In normal mode, press and hold [ MODE/SET ] and [ MAX/MIN/ALARM ]
simultaneously for approx. 5 seconds to enter calibration mode. Thevalue for
thewind speed’s calibration factor will begin to flash (default = 1).
2. Adjust thevalue between 0.75 and 1.25, where:
calibrated wind speed = calibration factor x measured wind speed.
3. Press [ MODE/SET ] again to adjust thevalue for theamount of rain. Thevalue for
theamount of rain’s calibration factor will begin to flash (default = 1).
4. Adjust thevalue between 0.75 and 1.25, where:
calibrated amount of rain = calibration factor x measured amount of rain.
5. Press [ MODE/SET ] again to adjust thevalue for absolute air pressure.
Thevalue for absolute air pressure will begin to flash.
6. Adjust thevalue to correspond with your reference value. Thevalue can be
changed in steps of 0.1 hPa.
7. Press [ MODE/SET ] again to adjust thevalue for relative air pressure.
Thevalue for relative air pressure will begin to flash.
8. Adjust thevalue to correspond with your reference value. Thevalue can be
changed in steps of 0.1 hPa.
Final mounting
Information
We recommend that you familiarise yourself with theweather station and its sensors
before you mount thedevices in their final locations. This gives you theopportunity to
easily calibrate thesensors and to test thevarious functions of theweather station.
Choice of location
Things to consider before you mount thedevices:
• Therain gauge should be cleaned once per year, and batteries must be replaced
once every two years. Ensure, therefore, that thesensors are mounted in easily
accessible locations.
• Ensure that therain gauge and anemometer are not obstructed by any nearby
trees or buildings. Thegeneral rule is to mount thesensors at adistance that is
at least 4 times theheight of nearby obstructions – e.g. if abuilding is 6 m high,
thesensors should be mounted (4×6 =) 24m away.
• Avoid radiated heat from nearby buildings, roofs, etc. Generally speaking, temperature
sensors should be mounted in theshade approx. 1.5m above theground.
• Test thesensors in their intended locations before mounting them. Therange can be
affected by thetype of obstacles located between thetransmitter and thereceiver
(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 also
have anegative impact on thetransmission range.
