Performing leak test
With the leak proof test, the system is checked by the device (incl. the con-
densate separator) up to the probe spike on undensity. The internal gas
pump generates in addition a sub pressure which is measured over the built-
in draft sensor and is observed for a period of 10 seconds. Based on the de-
crease of pressure the leakness of the system will be determined.
Operation:
►
Connect the hose to the analyzer as shown in the figure below.
►
Go to the Extras menu.
►
Select Leak proof test.
►
Press OK.
The menu Leak proof test appears.
►
Ensure that the hose is installed.
Pressure is established.
A message appears if the leak test was passed or not.
►
Remove the hose.
If the leak proof test is not passed the probe must be checked including the
hosing as well as the condensate separator.
If no undensity is ascertained in these external parts the analyzer has to be
checked in a service department (worldwide service departments see
