Narrative:

I was making the welcome aboard PA and the first officer was climbing the aircraft to FL280. We set and acknowledged FL280 (which a check airman jump seater also said he saw). As I was finishing the PA, I noticed we were climbing through FL280. We climbed to FL285 before descending to FL280. Somehow the altitude alert system was set at FL290. There were no traffic conflicts.
