Wet Bulb Calibration

Post by hopeyeu »

I can't seem to get the wet bulb calibration to work.

Cumulus is set up for an Instromet station and the 'extra sensor' box checked to reveal the wet bulb sensor as the extra temperature sensor. However, when I change the wet bulb calibration setting nothing happens.

Calibration of relative humidity is fine when the 'extra sensor' box is unchecked.

Maybe the extra sensor being shown is not the station's wet bulb sensor?

With 'extra sensors' selected, the second temperature reading is used simply as an extra temperature reading (with no calibration possible). With it unselected, the second temperature reading is used as the wet bulb temperature, to which the wet bulb calibration settings are applied.
