I put a Perfectflight MAWD and SLCF in a homemade vacuum chamber contraption. Christmas tree lights as deployment events. Both altimeters record the same altitude, but with a slight time shift. No biggie on that. However, during the test, I clearly noticed that the MAWD charges went off several seconds before the SLCF charges. Indeed, the data download of the SLCF shows Drogue and Main events occurring essentially on the ground at the end of my simulated flight (the MAWD does not report Drogue and Main event times.)
These MAWD and SLCF altimeters fly just fine in real life and fire the events correctly. Any idea why the vacuum ground test may confuse the SLCF (but apparently not the MAWD?)
I would contact Perfectflight directly, but recent threads show that their communications are MIA at this time.
