7.7. Usage capability test (option)
What is the usage capability test?
The Usage capability test helps to determine and judge leakages (gas leakage) in low
pressure gas pipes.
Tested will be all in operation or repaired pipes with all faucets, however without gas units and
their regulators and security devices. The gas meter can be included in this test (using
backward test).
The usage capabilities test my not be performed when:
New installed pipes (= pipes within warranty)
Pipes that had a limited usage capability or a NO usage capability and had been repaired to
be used
Not in use pipes which want to be used again
Pipes in middle- and high-pressure range.
Test medium: Air or Methane
Test pressure: 23 mbar according to DVGW worksheet G600.
Unlimited usage capability: > 0 l/h to < 1,0 l/h
The pipe can be used for unlimited time without repair.
Limited usage capability: >1,0 l/h up to < 5,0 l/h
The pipe may be used for a maximum of 4 weeks. Within these 4 weeks the pipe must be
repaired to achieve Unlimited Usage Capacity again (Leak-tight test).
NO usage capability: > 5,0 l/h
The use of this pipe must be stopped immediately. Take action to determine the defect.
Important is the technical security judgment:
Also, a leak tight gas pipe can have limited or no usage capability. The physical condition
must be considered as well!
Once you smell gas the system is leaking. The above-mentioned usage capability grading’s
do not apply.

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 insert 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 DM9600 uses the pressure drop to calculate the pipe volume.
Please follow the instructions on the DM9600 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 indicated 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 smaller than 3 l.
Entering additional parameters
Entered operating pressure lower than 30 mbar – a reference operating pressure of 23 mbar
will be used for calculations.
Entered operating pressure higher than 30 mbar – the actual entered value will be used for
calculations.
Under “MEDIUM” you can select between air and Methane. It is important to select the
medium that you are using to get the correct results. Methane can escape easier than air in a
leakage situation.
The results are always based on Methane

8. Data storage
8.1. Data storage structure
The main component of data storage is the site. Each site has a distinct site number and 8
user definable text components which can be used for the address, customer name and so
on. The DM9600 can save up to 500 different sites.
New sites can be generated. Modifications and additions can be transferred using the PC
program MRU Win.
Attention: Sites that have been created in the DM9600 will NOT be transferred back to the
PC. Only measurement results will be transferred from the DM9600 to the PC which will be
identified by the site number.
Measurement results are stored and must be assigned to a site.
8.2. Measurements in the data storage menu
View measurements
Measured results can be viewed in the menu „view measurements“.
Once selected you will see an overview of the different measurement modes with the number
of saved results for each mode.
• Select one of the available modes.
• You will first see context information about the stored measurement. Use
the arrow buttons to jump in between different stored measurements.
• Press „view“to s ee the details of the selected measurement. Results will be
displayed as they are defined in the measurement screen.
With „back „you will return to the context information screen.
Only logged measurements will display the measured time, the interval and the number of
measurements.
Attention:
It may take a bit longer to read the results if the number of measurements or the logged
measurements have a high data volume.
Delete measurements
You can:
• Delete single measurements when pressing the delete button while the
measurement is being displayed.
• Or delete all measurements of a measurement mode. You will be asked to
confirm your intention to delete all measurements.

In the menu sites, you can:
• View all data of the stored site
• Add new sites
• Delete sites
• Any modifications to the sites will not be transferred to the PC
Attention:
Sites created in the DM9600 will not be transferred to the PC.
View sites
In the menu „Sites administration“each site will be displayed with:
• The distinct site number, which is displayed in blue to indicate it’s
significance,
• And addition 8 user definable fields.
You can page through the sites using the arrow buttons left and right.
Add new sites
New sites can be added and modified in the „Sites administration“menu.
Select “new” to add a new site. You will then see:
• The first line which must have a distinct site number for identification. The
DM9600 can also create a new site number (the next available site number
will be selected).
• All other lines are user definable lines for address, customer name and so
on.
(These lines can only be filled with a PC program like the MRU4Win)

8.4. Data transfer using the SD-Card
For data transfer, we use the CSV format
CSV is a simple file format used to store tabular data, such as a spreadsheet or database.
Files in the CSV format can be imported to and exported from programs that store data in
tables, such as Microsoft Excel or OpenOffice Calc. CSV stands for "comma-separated
values"
• Import of sites Anlagen
• Export of sites
• Export of saves measurements
Import of sites
This function can be used to transfer a CSV file that has been created on a PC.
IMPORTANT: The file name must be “analgen.csv”!
The file may not contain any header information, meaning, the first line will contain actual
data.
Each line that is not empty and which doesn’t start with a comma (both would result in an
empty site number which is not permitted) will be transferred.
Each line and/or data set a maximum of nine lines will be transferred. A maximum of 24
numbers and letters are allowed for each line, everything longer than 24 letters/numbers will
be cut off.
A1-F1,A1-F2,A1-F3,A1-F4,A1-F5,A1-F6,A1-F7,A1-F8,A1-F9
A2-F1,A2-F2,A2-F3,A2-F4
A3-F1,A3-F2,,A3-F4,
A4-F1,,,A4-F4
A5-F1
Examples with 3 invalid sites: (reason for error)
,A1-F2,A1-F3,A1-F4,A1-F5,A1-F6,A1-F7,A1-F8,A1-F9 (Comma at the beginning)
(Space)
,A3-F2,A3-F3,A3-F4,A3-F5,A3-F6,A3-F7 (Comma at the beginning)
Important:
No check is performed inside the file or the DM9600 for duplicate site numbers (line1).
The DM9600 can handle duplicate numbers, however that can be difficulties later to assign
measurements to site numbers when exporting these back to the PC.
(see also 3. + 4. Export of measurements)
The DM9600 will mark duplicate site numbers after import. If the same file is imported to the
same DM9600 an indication will be displayed in red letters.

Exporting sites
This function can either be used as backup of the sites to a PC or to transfer them to a
different DM9600. This is very useful especially when modifications (like modified telephone
number, etc.) have been made manually in the Sites Administration of the DM9600 and these
modifications need to be updated in the PC program. Or, if the same sites must be installed in
a second DM9600.
The format of this file is identical as the one described in “Import of sites”.
Only the file name is different, in this case “ANLxxxxx.csv”. The xxxxx in the file name are
consecutive numbers containing zeros. The exported file can be used to import the sites into
another DM9600, however the name must be changed to “anlagen.CSV” before it can be
used for import.
Exporting measurements
This function is used to export measurements to a PC.
Attention: this is not a backup function and the results can’t be transferred to another
DM9600!
The created file has the file name “TMPxxxxx.csv” the xxxxx in the file name are consecutive
numbers containing zeros
The created file has a header with information like, Site number, Date/time, measuring values
and units, all the information that is also stored inside the unit.
Here is an example:
Attention:
It can take up to 2 minutes to export measurements, depending on the number of
measurements that are being exported.
8.5. Information about the data storage
In the „menu storage „you select „Memory info” to get information about
the available storage capacity of the unit. You will see the number of
stored sites (max 500) and the number of stored measurements (max
1000).
