dpreview does not comment (that I could find) on a 2/3 stop ISO error on 
the A200 as they do on the A1.  But I can testify as did AG that the A1 
definitely has 2/3 stop greater sensitivity than indicated by the ISO 
dial.  You didn't say which way your exposures were going but if you're 
getting overexposure with the handheld meter then try setting your meter 
for 2/3 stop higher ISO than indicated on the camera, ie;
  50 =   80
100 =  160
200 =  320
400 =  640
800 = 1280

Tha A2 may also have its own peculiarities and you may have to do some 
testing to figure out what the error is.  But, given there's a precedent 
in the Minolta line I wouldn't be too quick to blame the meter.
