| On the other hand some conditions might occur that don’t allows correct measurements for some time like very heavy snowfall or reflections of already fallen snow. I did not investigate those things, but I want to say that it’s important to choose the parameters according to your needs. I suggest a ratio that the filter is renewed between 40 and 60 minutes. | On the other hand some conditions might occur that don’t allows correct measurements for some time like very heavy snowfall or reflections of already fallen snow.
