Checking measured values

1. Call up the "Meas. funcs" 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 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>.
Fig. 28: Excerpt from the test protocol
1 Measured value: External pressure value
2 Measured value: Test bench press.val. upst.of filter
3 Measured value: Test bench pressure value
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
(refer to Fig. 28). The difference in pressure must
not exceed 0,5 MPa.
Calibration must be repeated if the pressure
difference is > 0,5 MPa.
