Checking measured values

1. Call up the "Measurement functions" selection
menu with <F7>.
2. Select the "Automatic on/off" menu item and
activate the automatic mode function with <F12>.
? The automatic mode symbol flashes in the
operating status display.
? The specified values are set and the waiting time
commences. On completion of the waiting time,
the system software switches automatically to the
next test step.
3. In the event of the message "
No further test step! Results with
F12 >>.
" call up the protocol with <F12>.
4. At all verification points, compare the measured
values Test bench pressure value and Test bench
press.val. upst.of filter to External pressure value.
The difference in pressure must not exceed 0.5 MPa.
Calibration must be repeated if the pressure differ-
ence is > 0.5 MPa.
