Important Tips
Do not block the fresh air opening for the
fresh air pump!
In order to get correct measurement values:
-allow 1 min for auto-zero in fresh air
-allow at least 2 mins. for stable readings before
taking the measurement
Adjustments on burners and boilers
should be made only by specialists
who are familiar with these installations.
1. Charge the internal battery regularly.
(An unused analyzer should be charged at least
once per month.)
2. Never store the unit with a discharged battery!
The Ecom-B is not suitable for continuous emis-
sions testing. Please allow at least 10 minutes of
fresh air purging for each hour of testing.
The following substances impair the instru-
ment´s operation:
- cleaning agents
- degreasers
- wax polishes
- adhesives
- anything containing formaldehyde

3. Gas Cooler (option)
How it works:
Exhaust gas with a temperature over the steam dew point (35 - 65 °C)
is drawn into a long gas path. Then, it is pushed through a metal coat-
ed surface with strong thermal conductivity. The gas radiates its heat
to this metal surface. A Peltier element (semi-conductor cooling ele-
ment) operated by a continuous current is connected with the metal
surface and a second metal body with cooling ribs and ventilation
slots.
The flow through the Peltier element creates a heat transfer from
WARM to COLD. This drains the heat from the metal body and from
the gas then transfers it to the outer cooling body. This heat is con-
veyed thru vertical forced ventilation to the surrounding air.
The condensation created by the heat loss of the gas drops in a re-
ceptacle and is pumped out when needed by a hose pump.
The Peltier cooler can be switched off in the following manner:
In the measurement menu, press <Enter>, select <Peltier I/0> and
press <Enter> again (To turn the Peltier cooler switch on, just repeat
this procedure).

4. Power Supply
The Ecom-D comes with an external charger. The analyzer can also
be powered via the internal battery (6 V; 3.8 Ah). The battery should
be recharged as needed (Indicted by a warning sound and display
light). The battery charging status can be by checked looking at the
voltage indication on the display (menu "Control" - Info key). The bat-
tery warning is activated when <Accu> is lower than 5.9 V.
At 5.8 V, the battery does not have enough power to operate the ana-
lyzer. At this point, the instrument must be charged via the external
charger.
5. Data Memory
The multi-media card enables the storage of measurements. The
measurement results are written in a text file (J2KDV.txt). Data format
information can be found in the appendix. The files can be transferred
to a PC via the memory card.
In order to use the memory card function:
- The card must have at least 32 MB of memory, with a maximum of 2
GB
- The card must be formatted on 16 bit FAT
- It must be either an SD or MM card from rbr
- The PC must have a card reader from ECOM, Belkin, or SanDisk
Used batteries can either be returned
to Ecom or taken to local recycling centers!

Page 8 ECOM-D
Inserting the card
Insert the multi-media card as shown. Make sure
that the card is inserted completely (so that none of
the card is seen) and is secured in place.
6. Analyzer Start-Up
Once the instrument is switched on (key <I/0>), the
main menu is displayed.
6 sub-menus with the following functions (non-
visible sub-menus can be viewed with the arrow
keys) are displayed:
- Gas analysis : Perform gas analysis
- Soot...Oil trace : Input of soot measurement results
- Data processing : Save measurements / Data transfer
(Multi-media card required)
- Adjustments : Modify instrument settings
- Control : Check operation state of instrument
Do not remove the card while opening/saving
data.
This can cause damage to the card, card
reader, or data loss.
Always position the probe in the exhaust pipe
once the auto-zero phase is over!
Always use a filtering system as per our rec-
ommendation for combustion plants
firing solid combustibles!

The position of the measured and calculated values (gas analysis
sub-menu) on the display pages may be changed at any time. To
change these positions:
- Press <Enter> / <Display values> / <Enter> to begin
- Select the line with the arrow keys (Up/Down)
- Select desired parameter with the arrow keys (Right/Left)
- Repeat procedure until desired layout is completed
- Press <Enter> when finished
Connect the sample line to the <Gas Connection> plug, and position
the sampling probe in the exhaust channel, so that the thermocouple
is fully surrounded with the gas (see drawing).
Perform the measurement in the core stream of the exhaust gas
channel with the probe placed in the hottest gas temperature area. As
you move the probe toward the center of the exhaust, the display will
show an up arrow, indicating an increase in the measured tempera-
ture. If the probe is pulled away from the exhaust, an arrow pointing
down is displayed, indicating a decrease in temperature. If no temper-
ature change is shown for at least 3 seconds, the arrow display will
disappear, indicating the lack of change.

CO2, efficiency, losses, excess air and dew point are calculated val-
ues. They can only be calculated if values for the basic parameters
like O2and the temperatures are available. Make sure that:
O2< 20.5 % and T.Gas - T.Air > + 5 °C
The current barometric pressure must be typed in (in the <Adjust-
ments> menu) for the dew point to be calculated accurately. If the gas
temperature falls below the dew point (between 25 and 65 °C), then
efficiency will be calculated with condensation gain. In this case, a (K)
is displayed after <Efficiency>.
Correct measurement values are displayed after a short delay. This is
necessary so the gas has time to reach the sensors and to build-up a
stable electrochemical reaction for the sensors. This time period lasts
approx. 1 to 1.5 minute. For recording, printout and evaluation wait
until the values do not change anymore. If deviations higher than 2
ppm still occur with the gas values, it may be due to unstable pressure
conditions in theexhaust channel.
If the measurement values are stable, press the key
<Record> (disk symbol) to transfer the values in the
intermediate memory (caution: store gas analysis,
CO, O2check and draft measurements separately).
They will be kept there for a later printout and, if
need be, for a final data record storage.
If a printout of the values needs to be made as the measurement is
taking place, simply press <F2> (the complete content of the interme-
diate memory will beprinted).

The CO sensor is protected against over-saturation thanks to an in-
ternal program. If the 4000 ppm limit is exceeded, a purging pump is
activated which provides the sensor with fresh air. After sufficient
purging time (X behinds CO disappears), the sensor can be reinte-
grated into the measurement system with <F3>. You can do this au-
tomatically by selecting <Yes> in <Adjustments> / <Internal> / <CO-
Automatic>. The sensor can also be manually excluded from the
measurement system by pressing <F3>.
8.2. Draft Measurement
A trend indication for the draft conditions in the exhaust channel can
be viewed during the gas analysis. However, the draft will not be
stored together with the gas values when pressing <Record> be-
cause the differential pressure sensor tends to drift.
For an exact measurement, auto-zero this sensor just before sampling
and document the value.
The display shows the current value as well as the
recommendation to reset the zero point of the sen-
sor. Disconnect the draft hose from the instrument
for a short period and press <F4>. The analyzer will
then reset the sensor’s zero point.

Re-connect the draft tubing. The display shows the
exact measurement value which can be stored by
pressing <Record> and added to those results pre-
vious stored in the intermediate memory. The stored
value is shown on the display. Press <ESC> to exit
the draft measurement menu.
8.3. Flow measurement (option)
This measurement can be done with a pitot tube.
First, the pitot factor of the pitot tube must be en-
tered by going to <Adjustments> / <Internal> /
<Pitot factor>). After connecting the pitot tube to
the analyzer, the zero point of the sensor can be set
with <F4>. Enter the cross section of the flow chan-
nel with <F1>. This is needed for the calculation of
the flow rate. After the pitot tube is positioned in the
flow channel, the display shows the speed (m/s) and
the flow rate (Nm3/h). If the value is stable, press
<Record> to store the value in the intermediate
memory. If a printout of the values is needed during
the recording to the intermediate memory, press
<F2>. The complete content of the intermediate
memory will be printed out.

9. Mean Value Measurement (option)
The mean value measurement function allows you to sample meas-
urements in an adjustable time frame, and to calculate the average of
those results. Should the several measurement values or the average
calculation need to be saved, a save file has to be selected as de-
scribed in chapter 7. If the “Store” function is used, all measurements
will be placed in numeric order starting with the number of the first
saved file. If the “Store” function is not used, the results can be
stored on MMC with <Print> / <Memory -> M>.
Once the fresh air calibration is completed, select
<Mean values>. Before starting, <Measurement
time>, <Scanning>, <Printer> and <Record>
should be modified as needed. See their use below:
- Measurement time = the length of time the meas-
urements will occur
- Scanning = Time interval between the
measurements considered in the average value
calculation
- Printer = Documentation of
measurements of the average value calculation
- Store = All measurements for average
value calculation will be stored
<Measurement time> and <Scanning> can be adjusted as follows:
- Select value you want to change and confirm with <Enter>
- Set the desired time using the numerical keys:
0.01 = 1 sec = minimal value
