USER MANUAL DM9600
MRU GmbH, D-74172 Neckarsulm
38 / 57
Operation
To
be able to calculate the leakage rate first the pipe capacity must be
determined.
In the first screen of the usage capability test you are asked if you want
to determine the pipe capacity automatically. As alternative you can in-
sert the pipe capacity manually.
No - Enter pipe capacity manually
Automatic capacity determination
The capacity determination is done by extracting a defined volume from
the closed pipe system using the syringe. The analyzer uses the pressure
drop to calculate the pipe volume.
Please follow the instructions on the analyzer screen.
The syringe volume is not big enough to achieve the wanted differential
pressure, if the pipe volume is bigger than (>200 Liter). This will be indi-
cated with a red pressure value.
In this case the syringe volume can be increased using the
button
and you can take an additional syringe volume.
Continue with entering all additional parameters
Entering pipe volume manually
Enter the calculated pipe volume.
Entering range is 3 to 1000 l (standard value is 20 l).
The DM9600 will calculate with 3 l should the calculated value be small-
er than 3 l.
