. Data processing
.1. Data storage
The measurements made with the equipment can be assigned to a customer. For
each customer a file with file name is created on the memory card (e.g.:
DP3_0001.DAT). Into this file all measurements belonging to the customer are
written.
The files can be transferred to the PC using a card reader. ith the software
"DP3Report" a protocol for each check can be made. The following conditions
must be fulfilled for using a multi media card:
- min. card volume 32 MB - max.32 GB (UHC)
- card formatted on 16 bit FAT or FAT32
- SD cards from SanDisk recommended
- PC with card reader
.2. Edit customer
If the instrument gets switched on and a SD or MM
Card with no customer data is inserted the inquiry
follows whether you would like to edit a customer. If
the measurement is to be assigned to a customer,
press the key <F1> (<F > = no: Measurement is
made without allocation). Proceed as follows:
-select line to be filled out with the cursor keys
<up/down> and confirm with <Enter>
-select keyboard <F3>
(4 keyboard are available)
-select a character with the cursor keys
<up/down/right/left>
(selected character is black deposited)
-take over the character with <Enter> (the last
character can be deleted with <F2>)
-repeat the procedure, until the desired designation
is complete
-if a character is to be corrected, proceeded as
follows:
-interrupt the character selection with <F >
No customer
existing!

YES
NO
Never pull out cards during data record - data loss and damaging
of the data carrier possible!

-select the character to be corrected with the
cursor keys <right/left>
-activate the character selection with <F > and
correct the character
-return to line selection with <F1> and choose
the next line
If all necessary lines are filled out, a file is created
with <F1>. ith <ESC> you can leave to select a
control program.
.3. Select customer
ith the help of the software „DP3Report“ customer
data can be stored for the use at the DP3 on SD or
MM Card. If the instrument gets switched on and a
SD or MM Card with customer data is inserted a
customer for allocation can be selected with "Search
for/Scroll" / <Enter>:
Scroll:
Select „Scroll“, if you want to find the customer with the help of the cursor keys
<up/down>. Further functions are:
<F1> = to the first customer
<F2> = 10 customers forward
<F3> = 10 customers backward
Search for:
Select „Search for“, if you want to find the customer by the input of at least 3
connected characters. Edit 3 characters as described in the chapter before and
start the search with <Enter>. All agreements with the character sequence are
picked out. The selection can be paged through with <F3> (with <F1> to the be-
ginning of the selection).
If the desired customer is found, select with <Enter>. ith „View/Modify“ the
customer data can be viewed and modified.
Format:
This function is usually needed by initial adjustment of the instrument at our facto-
ry (preparation of SD or MM Card for data recording).
Caution: All stored values will be cancelled! Please switch instrument after
formatting off and on again!

5.3.2. Pressure test
The pressure test acc. to TRF at liquid gas pipes is
registered as a control pragram in the ecom-DP3.
Proceed as follows:
1. Scroll with the cursor keys <up/down> in the
menu "Liquid gas" to the menu point „Pressure
test“. Activate the menu point with <Enter>.
2. Check if necessary the values of stabilisation time,
measurement time and test pressure with <F1>
(back with <ESC>).
3. Lock the gas pipe with a suitable adapter (test
stopple, high pressure stopple or one-pipe counter
cap).
4. Connect the components as described in
chapter 3.
5. Start the control program with <Enter> (the pump
of the instrument is building up the adjusted pres-
sure).
6. ait for stabilisation time (if the pressure remains
in the range „test pressure - 10%" during stabilisation
time, so the measurement time will start). If neces-
sary the stabilisation time can be terminated with
<F1>.
7. Once the measurement time is over, the result is
displayed and can be printed with <Print>.
8. If the menu „Pressure test“ is selected again, so
the result can be called up with <F > (as long as the
ecom-DP3 is on) or a new measurement can be
started with <F1>.

5.3.3. Pressure test 0 – 0 bar
The pressure test 0 - 40 bar at liquid gas pipes is
registered as a control pragram in the ecom-DP3.
Proceed as follows:
1. Scroll with the cursor keys <up/down> in the
menu "Liquid gas" to the menu point „Pressure
test 0 – 0 bar“. Activate the menu point with <En-
ter>.
2. Check if necessary the values of stabilisation time,
measurement time and test pressure with <F1>
(back with <ESC>).
3. Connect the external pressure sensor to the liquid
gas pipe.
4. Connect the external pressure sensor as de-
scribed in chapter 3.
5. Start the control program with <Enter> (the pump
of the instrument is building up the adjusted pres-
sure).
6. ait for stabilisation time (if the pressure remains
in the range „test pressure - 10%" during stabilisation
time, so the measurement time will start). If neces-
sary the stabilisation time can be terminated with
<F1>.
7. Once the measurement time is over, the result is
displayed and can be printed with <Print>.
8. If the menu „Pressure test 0 – 0 bar“ is select-
ed again, so the result can be called up with <F >
(as long as the ecom-DP3 is on) or a new meas-
urement can be started with <F1>.
