Outside Temperature Multiplier

[colinpb]

Due to the positioning of my WH3080 it’s needed a temperature calibration since I first set up. However sensors are no longer available for my Oregon Scientific BAR 113, so I have finally got a BAR 206; a fine unit, with the clever feature of automatically scanning up to 3 sensors at 5 second intervals. Now I can see what’s needed, so my question is as follows.

I would like to use the temperature multiplier, is it possible to put a 3 decimal place figure in cumulus; e.g. 0.925. Or should I put it directly into the cumulus.ini which appears to handle this sort of figure; e.g. wind multiplier and 0.0079 conversion factor. If I use 0.925 to produce a lower (cooler) value what happens below zero, does cumulus give a larger (cooler) number? For example -5.0 would become -5.4

Yes, the calibration settings allow 3 decimal places.

If I use 0.925 to produce a lower (cooler) value what happens below zero, does cumulus give a larger (cooler) number? For example -5.0 would become -5.4

It's simply a multiplier; it multiplies the actual reading by the figure you supply. -5 * 0.925 = -4.625
