Weather forecasting and trend

The weather station can sense variations in atmos-

pheric pressure and hence is able to forecast the

weather 12-24 hours ahead within a radius of

30-50 km from the receiver.

Trend

When

appears the atmospheric pressure is

rising and the weather is expected to improve.

When

appears the atmospheric pressure is

falling and the weather is expected to take a turn

for the worse.

When

appears variations in atmospheric

pressure are stable.

Atmospheric pressure history

The curve shows the atmospheric pressure trend

over the past 12 hours.

Notes:

• When the weather station has been newly installed

you should disregard its weather forecasts for the

ﬁrst 12-24 hours as it needs some time in a new

location before it can give reliable forecasts.

• Absolute precision cannot be guaranteed. The

weather forecasting function has a reliability of

75% because it has been designed for use in

many different types of environment.

• If the weather station is moved to a location

with a notably different height above sea level

compared to its original location, remove the

batteries and re-insert them after ca. 20 seconds.

Doing this prevents the weather station from

sensing differences in the atmospheric pressure

and thereby giving a wrong forecast. Disregard

weather forecasts the ﬁrst 24 hours after changing

batteries. By doing this the weather station is not

tricked into sensing difference in pressure and

thus give an incorrect forecast.

Temperature and humidity trend

The trend arrows appear to the right of the tempera-

ture and humidity readings.

Appears when the most recent temperature or

humidity measurements are 1 °C or 5 % higher than

the preceding temperature or humidity readings.

Appears when the most recent temperature or

humidity measurements are 1 °C or 5 % lower than

the preceding temperature or humidity readings.

Appears when the most recent temperature or

humidity measurements are within +/- 1 °C or +/- 5 %

of the preceding temperature or humidity readings.

Reading max. and min. temperatures

1. Press MEM/DUAL TIME to read the highest

temperature, humidity and pressure readings.

“MAX” appears in the display.

2. Press MEM/DUAL TIME again to read the lowest

temperature, humidity and pressure readings.

“MIN” appears in the display.

Resetting max. and min.

When the max. - and min. temperature appear press

and hold MEM/DUAL TIME to reset the highest and

lowest temperature readings.

Care and maintenance

Wipe off the device with a dry rag. Never use

solvents or abrasive cleaning agents.

Troubleshooting

The display

is blank.

• Press once the RESET button at

• Check and replace the

receiver batteries.

The tempe-

rature and

appears on the display

synchronisation has succeeded.

Temperature,

humidity or

All of a sudden, my weather station has started beeping every 5 minutes and that's not the alarm. A sign appears in the left corner when it beeps. Have reset but it does not help.

Carefully open the weather station so that the cables do not come loose. Carefully disconnect the round black sound sensor. Throw. Reassemble the weather station. You can not have an alarm function now, but otherwise it works!

It happened to us now, too, after many years. I took the batteries out of both the weather station and transmitter and left them without power overnight. When I connected them again in the morning, the beeping sound was gone :)

Frequently Asked Questions about Clas Ohlson IW003 Weather Station

Our support team searches for useful product information and answers to frequently asked questions. If you find an inaccuracy in our frequently asked questions, please let us know by using our contact form.

My weather station prediced it would rain, but this didn't happen. Why is that? Verified

The prediction on the weather station is based on air pressure. In general low pressure means bad weather and high pressure means good weather. It's possible the weather pattern develops differently than the air pressure predicts.

What is the best location for a weather station and its sensors? Verified

The weather station itself is placed inside and needs to be kept away from heat sources such as the kitchen, windows or electrical appliances. A separate outside temperature sensor needs to placed in shadow and at least 1,25m above the ground. A rain sensor needs to be placed in an open area where it can always collect rain. A wind sensor needs to be placed in an open area too, with any obstacles influencing the wind.

My weather station has a rain gauge, can it also measure the amount of snowfall? Verified

Some rain gauges are equipped with a heating element, making the snow melt and allowing it to be measured. Without heating element the rain gauge will clog and no measurement can be performed.

A battery in my device is oxidized, can I still safely use it? Verified

Ja, the device can still be safely used. Firstly, remove the oxidizd battery. Never use bare hands to do this. Then clean the battery compartment with a cotton swab dipped in vinegar or lemon juice. Let it dry and insert new batteries.

Can I leave a replacable battery in a device for a long time? Verified

Replacable batteries can remain in a device for a long time if the device is in use. When a device is being stored for a long time it is advisable to remove the batteries to prevent oxidation.
