Narrative:
We had been cleared to maintain 2000 ft until established. The localizer was bracketed and I had a clear view of the runway straight ahead. A distraction occurred in the cockpit -- the autoplt was engaged. As the distraction was addressed, approach control indicated low altitude warning. This was immediately addressed. Solution: never deviate from normal procedures, no matter how good the WX or what the reason.
