Notice in the "group" field of this linked photo
that the fields of data the 200 20V 3b put out (10 readings) are on "GROUP"
000 not 0....
the photo shows my first attempt in reading these blocks. hence the 001 ,
002, 004 "looking" for datd fields......... The Bentley shows what each value
range is in the tables section of the back of the book Vol1 AFAIK. Page D2 -
440 -1 thru 450-4
