Pressure Transducer Maximum Rating
(P HI)
The Pressure Transducer Maximum Rating
establishes the maximum rating of the
pressure transducer. This number can be
found stamped on the pressure transducer. If
the transducer has a maximum rating of 145
psi (10 bar in SI mode) and the number is
shown on the display, advance to the next
step by pressing the Program key. If the
maximum rating is 363 psi
(25 bar in SI mode), use the Plus or Minus
keys to change the value. Press the Program
key to advance to the next step.
