If you set an altitude in your WMR200 console it will mean that the console and WD will show different pressure values unless you set an equivalent offset value for pressure in Control Panel => Initial Rain & Offsets.
Here’s some background…
Setting an altitude in the WMR200 makes the console display a sea level equivalent value.
WD receives the raw (i.e. not adjusted to sea level equivalent) value from the WMR200.
Setting a altitude in WD does not affect the storage or presentation of the pressure value.
So, to get the sea level equivalent value in WD you need to apply an offset.
