Hello Nico
The Vue, GE Druck graph indicates that “my” Davis Vue console pressure transducer in operating well within the Davis specification of ±1.0 mbar. You can also conclude this from the Vue, ASI DBX2 graph Of course, the Vue and DBX2 barometers get periodically single-point calibrated (due to long-term drift) to insure they meet specifications. The Vue console is setup to send altimeter/ QNH pressure, so the data going to CWOP is correct.
I should say that the GE Druck Barometer introduced no significant error into the study.
Thanks,
James
