Narrative:
On the VOR runway 8 approach into pns with scattered thunderstorms and occasional moderate turbulence we had a loss of 400 ft. This occurred after capturing in altitude mode 2000 ft; and then selecting 800 ft; which was the MDA for the approach. I was the PNF and told the first officer to climb back up to 2000 ft. Tower advised; 'low altitude alert;' at approximately the same time; this altitude deviation occurred just prior to the FAF. At the gate the first officer and I confirmed we captured altitude mode before selecting MDA. I believe later vertical speed mode was selected by accident due to the turbulent conditions.

Title: EMB140 FLT CREW HAS AN ALTDEV DURING APCH TO PNS.
Narrative: ON THE VOR RWY 8 APCH INTO PNS WITH SCATTERED TSTMS AND OCCASIONAL MODERATE TURB WE HAD A LOSS OF 400 FT. THIS OCCURRED AFTER CAPTURING IN ALT MODE 2000 FT; AND THEN SELECTING 800 FT; WHICH WAS THE MDA FOR THE APCH. I WAS THE PNF AND TOLD THE FO TO CLB BACK UP TO 2000 FT. TWR ADVISED; 'LOW ALT ALERT;' AT APPROX THE SAME TIME; THIS ALTDEV OCCURRED JUST PRIOR TO THE FAF. AT THE GATE THE FO AND I CONFIRMED WE CAPTURED ALT MODE BEFORE SELECTING MDA. I BELIEVE LATER VERT SPD MODE WAS SELECTED BY ACCIDENT DUE TO THE TURBULENT CONDITIONS.
