Altimeter high when cold

[LOb]

Hi, now that the fall has come with lower tempratures my D10A agian shows to high altitude when powered on. On the ground it is about 50 feet high. I have an analogue altimeter as well and both are on the same QNH. The altimters will align after a while, maybe 10 minutes, but it looks strange when doing the checks on the ground befeore take off.

This is expected behavior. In extreme cold conditions, the EFIS needs a few minutes to temperature-stabilize as it self-heats on power-up. How cold is it when you're first powering up?

OK, last Saturday it was like +7C and it showed 130 ft when powered on while it on warmer days shows 60ft which also is the correct altitude for the airfield.
