VOLUME MEASURE
Selected test is v alid for volume pipes up to 25 dm
3
(25 liters). It is not
required to know and enter the volume of the pipe since it is assumed to
be 25 dm
3
. In this way the leakage rate is actually rounded up and better
guarantee the v alidity of a “compliant” result. The test procedure is not
described in details because it is the same as the calculated volume
shown in the f low chart except f or the v olume size.
Automatically.
When the v olume
measurement procedure
is correctly terminated,
The 4400 shows the
m e as ured v a lue ,
otherwise it requires to
repeat the gas injection
with the syringe.
