3. Gas Cooler (option)
Exhaust gas with a temperature over the steam dew point (35 - 65
°C) is flown spiral via a long gas path thru a surface coated metal
body with good thermal conductivity. The gas radiates its heat to this
metal body. A Peltier element (semi-conductor cooling element)
flown by a continuous current is thermal connected with this body
and with a second metal body with cooling ribs and ventilation slots.
The flow thru the Peltier element creates a heat transfer from WARM
to COLD, drains the heat of the metal body flown by gas and con-
veys it to the outer cooling body. This heat is conveyed thru a vertical
forced ventilation to the surrounding air.
The condensation issued by the heat loss of the gas drops in a re-
ceptacle and is pumped out on request by a periodically working
hose pump.
By accumulator operation, the Peltier cooler can be switched off.
In the measurement menu press hereto <Enter>, select the menu
point „Peltier I/0“ and press again <Enter> (for Peltier cooler switch
on, just repeat this procedure).

4. Power Supply
The ecom-EN2 comes with an external charger. The analyser can
also be powered via the internal accumulator for a while (6 V; 3.8
Ah). The accumulator recharge should be started when the instru-
ment requires to (acoustical warning and display indication). The
accumulator charging stand can be checked looking at the voltage
indication on the display (menu "Control" - Info key). The battery
warning is activated when the value „Accu“ is smaller than 5.7 V.
By 5.4 V the power operation via battery is no more possible; the
instrument must be further powered via the external charger.
5. Data Memory
The multi-media card enables the storage of punctual measure-
ments; the gathered values are written in a text file (J2KDV.txt). Data
format information is to be found in the appendix. The files can be
transferred to a PC via a card reader.
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
Used accumulators can either be returned
to us or brought to recycling stations of
public waste disposal companies
respectively to stores selling accumulators!

The position of the measured and calculated values (gas analysis
sub-menu) on the display pages is free selectable. For alteration of
the existing succession, proceed as follows:
- Press <Enter> / „Display values“ / <Enter> to activate the
function
- select line with cursor keys (Up/Down)
- select desired parameter with cursor keys (Right/Left)

Connect the sampling tubing on the instrument to the plug „Connec-
tion gas“. 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 (probe placed in the hottest gas temperature area). A trend
indication for T.Gas easies the core stream search. As long as the
display shows an arrow in upwards direction, the measured tempera-
ture increases, it means the probe tip moves towards the core
stream center. If an arrow in downwards direction is displayed, it
means you move the probe away from the core stream and the tem-
perature sinks. If no temperature change is shown for at least 3 sec-
onds, so the trend indication will disappear.

, efficiency, losses, excess air and dew point are calculated val-
ues. They can only be calculated if realistic values for the basic pa-
rameters like O
2
and the temperatures are available. It must be as-
certained that:
O
2
< 20,5 % and T.Gas - T.Air > + 5 °C
are given. The dew point can only be calculated accurately if, in the
menu "Adjustments", the current barometric air pressure value has
been inputted. If the gas temperature falls below the dew point (be-
tween 25 and 65 °C), so efficiency will be calculated with condensa-
tion gain. In this case a (K) is displayed after „Efficiency“.
Correct measurement values are displayed first after a short delay,
necessary for the gas transport and the build-up of a stable electro-
chemical reaction to the sensors. This time period lasts approx. 1 to
1.5 minute. For recording, printout and evaluation, wait until the val-
ues do not change anymore. If deviations higher than 2 ppm still
occur by the gas values, they can be due to unstable pressure condi-
tions in the exhaust channel.
If the measurement values are stable
and the results can be printed out, press
the key <Record> (disk symbol) to
transfer the values in the intermediate
memory (caution: store separately gas
analysis, CO, O
2
check and draught
measurements). 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 should be made simultaneously to the in-
termediate recording, so press <F2> (the complete content of the
intermediate memory will be printed).

The CO sensor is protected against overload thanks to an internal
programme. If the 4000 ppm limit value is exceeded, so a purging
pump is activated which provides the sensor with fresh air. After
sufficient purging time (X behinds CO disappears) the sensor can be
reintegrated into the measurement system with <F3> (if you choose
„Yes“ at „Adjustments“ / „Internal“ / „CO-Automatic“ the CO
sensor switches to measurement automatically). The sensor can
also be manually be excluded from the measurement system with
<F3>.
8.2. CO Measurement (gas path check)
The gas channel check, called also CO measurement, is used for the
technical check of gas-fired plants in regards of safety aspects.
Hereby the CO concentration in the gas channel is measured after
the flow safety device and calculated on an undiluted value (oxygen
rest content in flue gas = 0%). As the gas conditions after the flow
safety device are no more homogeneous because of the flow in of
secondary air and consequently the core stream measurement can
be erratic, the analysis of the exhaust gas is performed along the
totality of the exhaust pipe diameter. A multi-hole probe (optional
accessory) is hereby used as sampling probe.
The calculated value shown on the line
„CO 0 %“ corresponds to the measured
CO concentration supposed the oxygen
content would amount 0% by the same
exhaust gas volume. It is consequently
the undiluted CO content in exhaust
gas. If the values indication is stable,
press <Record> to store the result in
the intermediate memory. If a printout of
the values should occur simultaneously
to the recording in the intermediate
memory press <F2> (the complete con-
tent of the intermediate memory will be
printed out).

8.3. O

check
This measurement is performed by room-independent plants like
gross calorific value plants. It is determined if exhaust gas flows into
the combustion air (O
2
content drops down / CO content can be pre-
sent) and herewith influence on the combustion quality.
For this analysis, a special multi-hole
probe (optional accessory) should be
used. If the value indicated is stable,
press <Record> to store the value in
the intermediate memory. If a printout of
the values should occur simultaneously
to the recording in the intermediate
memory, press <F2> (the complete
content of the intermediate memory will
be printed out).
8.4. Draught Measurement
A trend indication for the draught conditions in the exhaust channel
can already be viewed during the gas analysis. Nevertheless the
value for the chimney draught will not be stored together with the gas
values while pressing <Record> because the differential pressure
sensor tends to drifts because of its sensibility.
For an exact measurement, it is consequently advised to re-calibrate
this sensor just before sampling and documenting the value.
The display shows the current value as
well as the recommendation to re-set
the zero point of the sensor. Disconnect
the draught hose from the instrument for
a short moment and press <F4>. The
sensor is herewith re-calibrated.
