That new tester firmware made my bench read 30 volts high

Updated the firmware on my Fluke 787 last Tuesday before a 737 pitot static check. Everything looked fine on the display, but the actual output was way off, nearly flagged a bad air data computer that was totally fine. Tech support said the calibration values got wiped during the update, something in the release notes I skipped. Anyone else had a firmware update mess with their calibration constants? What do you guys use to verify after updates?

Whoa, that's scary. I always run a quick loop check against my calibrator after any update now.
