Narrative:

WX: local fog conditions RVR varying from 600-1000'. As we were taking runway for takeoff, tower stated 'we lost our rollout RVR' and reported 600,600, and 0. We discussed this and decided that with one transmissometer out we could go with 2 reporting 600-600. After takeoff some doubt about whether the rollout transmissometer was out or the RVR was down to 0 feet occurred. If the last was true, it would have changed our decision to takeoff.
