Human Factors
I purchased and had installed a Garmin G5 Electronic Flight Instrument. Although the system has an altimeter with Kollsman window; the existing altimeter must be retained per STC. During preflight (and following the checklist) I set the altimeter to current conditions/altitude on the old altimeter and forgot to set the one on the G5. The systems are not slaved and due to improper settings; the G5 read a couple hundred feet low.Because I have only flown with the G5 a couple of times; I used the older altimeter for takeoff. Once out of the pattern and on cruise; I started using the G5 and climbed to 3400 ft; leveled off; and set the altitude hold on the auto pilot. This would have kept me outside the Bravo which was 3500/10000 in my location. I was notified by ATC that I was in the Bravo. Looking at the both altimeters I saw (and then remembered) the G5 had the incorrect barometric pressure setting. I entered the correct setting (which caused the G5 to read 3600); descended below the bravo; and continued my flight without incident.
PA28 pilot reported penetrating class B airspace due to an incorrect setting on his new Garmin G5 electronic flight instrument display.
