My new magnetic level gave me a false reading on a 1980s Otis controller
I was setting up the guide rails in a Portland office building last week, and my new digital level showed everything was perfect. When we ran the car, it had a bad sway and we found the level was being thrown off by the strong magnets in the old motor generator. Has anyone else had a tool fail because of magnetic interference on a job?

Read an NTSB report that blamed magnetic interference for an elevator crash.
