Read the pressures in PR003
to PR006.
Do PR003 to PR006 match
the readings taken with the
pressure gauge (to within
0.2 bar)?Read the recommended
pressures in the UCH
(PR009 to PR012)
Do the values of these
parameters match the
manufacturer's
recommended
pressures?Write the recommended
pressures with command
