4. Data processing

4.1. 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. With 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

4.2. 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> (<F4> = 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 <F4>

No customer

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 <F4> 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>. With <ESC> you can leave to select a
control program.

4.3. Select customer

With 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 be­ginning of the selection).

If the desired customer is found, select with <Enter>. With „View/Modify“ the
customer data can be viewed and modified.

Format:
This function is usually needed by initial adjustment of the instrument at our facto­ry (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!

6.1. Single measurement

Beside the control programs the ecom-DP3 can be
used also to measure pressures, temperatures and
flow rates. Under „More measurements / Single
measurment“ all measured values are displayed on
a view. The measurement of the flow rate is made
with a pitot tube (connection P low 2).
If the measured values should be printed, press the
key <record> (disk symbol) to transfer the values in
the intermediate memory. The values can be printed
with the help of the <print> key (printer symbol). If a
printout of the values should be made simultaneous­ly to the intermediate recording, so press <F2> (the
intermediate memory will be printed).

After selection of a customer, a data logging of all
measured values can be started (and also stopped)
with <F3>. The interval time for the data logging can
be adjusted under „Adjustments / Scan data log-
ger“. With the help of the software „DP3Report“ the
data can be converted into a format readable for
Microsoft Excel.

6.2. Heating Check (Option)

The heating check is a simple, expressive process to evaluate a complete heating
plant (heat production, distribution and transfer) from the energetic point of view.
Hereby the single plant components get inspected by the heating engineer in a
combination of measurements and visual assessment and valued in regards of
their energetic quality acc. to a negative point system of maximum 100 points.
The higher the score, the farer the current plant is away from the desirable ener­getic stand and the higher the energy saving potential would be if modernisation
measures are conducted.

In combination with the special probes required here­to, the ecom-DP3 is able to perform the measure­ment of the heating check parameters: ventilation
losses and surface losses. Out of the main menu
point "More measurements", select the sub-menu
"Heating Check" and confirm with <Enter>.

With the menu point “Gas losses” gas loss values
can be converted to negative point system. The gas
loss value can be edit with the numerical keyboard.
After input the result is calculated with <Enter> and
stored in „Results“.

The surface losses measurement is performed by
a temperature sensor specific for surfaces. The tem­perature difference between boiler surface and room
temperature (air temperature sensor) is determined
and the percentual loss is calculated. Once the menu
point is called up, the boiler performance must be
inputed. To easy the measurement width, depth and
height of the boiler can also be entered (dimensions
will be memorized for surface calculation). Please
proceed as follows:

- activate respective input window
with <Enter>

- inputs values using the keys numerical
function

- confirm input with <Enter>
or:

- adjust values using the cursor
keys <Right/Left>

If no boiler dimensions are inputed, press <F1> (Start) to activate the measure­ment recording. Here the dimensions for all surfaces must be inputed.

Press <F3> (Start + ->) to start the real measure­ment. Proceed as follows:

- select surface (boiler side) to be
measured with <F1> or <F2>

- position surface sensor

- record temperature difference with
<Memory> - up to 10 values can be
recorded per surface out of which a
mean value will be calculated
automatically

- if need be, cancel measurements
with <F4>

- repeat this procedure for each surface

Once all surface temperatures have been determined, quit the menu with <ESC>.
The surface losses get automatically calculated. The value conversion in negative
points is available in the menu point „Results“.

The ventilation loss measurement is performed by
a flow probe 30 sec. after burner switch-off. This
measurement can be performed at the earliest 5 min.
after instrument´s switch-on as the pressure sensor
requires this period of time for stabilisation. Once the
menu is called up, the values for air pressure, exter­nal temperature, boiler performance and exhaust gas
pipe diameter must be inputed . Hereto proceed as
follows:

- open respective window with <Enter>

- input figures using numerical function of keys

- confirm input with <Enter>
or:

- adjust values using the cursor keys <Right/Left>

6.3. 4Pa measurement (option)

The simultaneous operation of room-dependent firing place and air evacuation
system can lead to dangerous low pressure conditions. With the ecom-DP3 it is
possible to check the low pressure limit value of 4 Pa and to document in a dia­gramme the time course of the low pressure value. Once the menu point is called
up, the measurement is to be performed as follows:

- connect capillary hose for room where burner is installed to „-“

- connect capillary hose for reference place (staircase or outside air to „+“

- operate firing and evacuation systems with maximal performance

- open window resp. connection door to burner room and check the correct
evacuation of the exhaust gases

- zero pressure sensor with <F4>

- position capillary hose for reference location

- start record pressure value course with <F1> (Start) (an acoustical signal is
issued every 30 sec. which can be deactivated / re-activated by pressing <F2>)

- record pressure by opened window resp. connection door

- close window resp. connection door after approx. 30 sec. and check low
pressure

- after approx. 30 sec. open window resp. connection door and check zero point

- close window resp. connection door after approx. 30 sec. and check low
pressure

- after approx. 30 sec. re-open window or connection door and check zero point

- after approx. 30 sec. close window resp. connection door and check low
pressure

Once the measurement time is completed, the diagramme can be viewed on the
display (use <F3> to emphasize illustration 1x, 2x, 4x, 8x times or A for automat­ic). Start a printout if needed with <Print>.

6.4. Pressure check

The pressure check (long term measurement up to
1500 hPa or 20 bar with external pressure sensor) is
registered as a control pragram in the ecom-DP3.
Proceed as follows:

1. Scroll with the cursor keys <up/down> in the
menu "More measurements" to the menu point

„Pressure check“. 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>). If the measurement time is set to
0, thecontrol program runs until it is interrupted.

3. Lock the gas pipe with a suitable adapter (test
stopple, high pressure stopple or one-pipe counter
cap) or connect the external pressure sensor.

4. Connect the components as described in
chapter 3.

5. Start the control program with <Enter> and built
up the adjusted pressure.

6. If the internal sensor (up to 1500 hPa) is used, the
needed pressure can be built up with the internal
pump (switch on and off with <F3>).

7. Wait for stabilisation time. If necessary the stabili­sation time can be terminated with <F1>.

8. Once the measurement time is over (or with <En-
ter> if measurement time = 0), the result is displayed
and can be printed with <Print>.

9. If the menu „Pressure check“ is selected again, so the result can be called
up with <F4> (as long as the ecom-DP3 is on) or a new measurement can be
started with <F1>.
