2.2. TEST TYPE SELECTION
Four types of test are available.
The PARAMETERS menu gives
access to four possible types of test :
leak test (LEAK TEST), pressure test
(BLOCAGE), desensitised mode test
(D. MODE) and an operator test
(OPERATOR); see the following
paragraph for explanations.
Put the cursor in front of the required
test type and confirm with the ENTER
key.

2.2.1. Leak test
The leak test is most suitable for measuring small
leaks (pressure drop). The following formula is used
to convert a leak expressed in units of flow to a drop
in pressure:
)(cm V x 0,0006
/min)(cm F
(Pa/s) P

=∆
F(cm
3
/min) = Leak flow
0.0006 = constant
V (cm

) = volume of the test part
∆P (Pa/s) = pressure drop
Example :
Part which has dP/dt = 50 Pa/s Part which has dP/dt = 1 Pa/s

The choice of working in Pa or in Pa/s depends on the application.
In all events, it must not be forgotten that the full scale of the sensor in Pa or Pa/s is
limited to 50 or 500 Pa depending on the instrument configuration.
