Decoders may at first appear to be quite difficult to understand but they are really quite simple. You need only remember:

Consequently, the manufacturer's data sheet must be consulted for each possible input code group.
Convert a reading of 18 in Hg vacuum to psia
A) 18 in Hg/2 = 9 psia (rounded) B) 30 + 18 in Hg vacuum = 48 in Hg absolute (rounded)48 in Hg absolute/2 = 24 psia (rounded) C) 30 — 18 in Hg vacuum = 12 in Hg absolute (rounded)12 in Hg absolute/2 = 6 psia (rounded) D) 18 in Hg + 30 = 48 psia (rounded)
