VOLUME MEASURE
Selected test is valid for volume pipes up to 18 dm
3
(18 liters). It is not
required to know and enter the volume of the pipe since it is assumed to
be 18 dm
3
. In this way the leakage rate is actually rounded up and better
guarantee the validity of a “compliant” result. The test procedure is not
described in details because it is the same as the calculated volume
shown in the flow chart except for the volume size.
Automatically.
When
the
volume
measurement procedure
is correctly terminated,
Chemist 400 shows the
m e a s u r e d
v a l u e ,
otherwise it requires to
repeat the gas injection
with the syringe.
