When the wait phase ends, the pressure verification phase, true and proper, begins (LEAKAGE PERIOD), with a duration of 10 minutes:
VACUUM TEST
LEAKAGE PERIOD
10:00
-0.79 bar 06:48
In this phase, a variation of up to ±0.02 bar is allowed, compared to the initial phase value.
Higher variations cause the test to fail. The time is counted down until the phase is completed.
When this phase is also completed, the pressure is brought back to atmospheric pressure.
VACUUM TEST
LEVELLING
-0.29 bar 17:19
When the program finishes, the display will read:
VACUUM TEST
TEST PASSED
-0.01 bar 17:44
The end of the program is signaled with a beep.
e If the pressure change exceeds the pre-set limit, the program is interrupted and alarm message is generated. See a complete description
of the alarms in Problem solution.
The duration of the test is about 18 minutes.
When the door is opened at the end of the program, a report of the test cycle is printed with all the salient data.
For complete details about printed reports, refer to Print report examples.
