The measurement phase ends when the time

This mode is used to save time and switch immediately to a new test before the time
runs out.
Used to calculate the leak rate Q equivalent to the pressure drop in time

parameter, programmed in the active test
leak rate Q, expressed in scc/m or scc/h.
The leak rate Q is calculated using the following formula which derives from the gen-
eral laws of (ideal) gases and which can also be applied to air, when it is close to am-
bient conditions:
T3 = 5 s =5/60 minutes, air temperature= 273 °K:
Q= (0.27 * (- 0.35) * 31.2 * 60) / (5 * 273) = - 0.13 scc/m
