2. Gas cooler (option)
Exhaust gas with a temperature over the steam dew point (35 to
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 (semiconductor cooling element)
flown by a continuous current is thermally 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
conveys 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 (either by the user or due to
the level monitoring) by a periodically working hose pump.
The sucking capacity of the gas conveying pump avoids a sufficient
dwell time of the gas with the condensate, so that wash out reactions
(NO

+H

) do not take place.
At the cooler outlet the gas has a temperature of ca. 5 °C with a rela-
tive saturation of nearly 100 % relative humidity (corresponds to a
water steam content < 7 g/m

).

3. Power supply
The basic module of the ecom-J2KN
pro
is delivered with internal
loading unit. The instrument can be operated upon a longer time
period with the internal accumulator (6 V; 7,2 Ah). Connecting the
internal charging unit to mains power is only compulsory to recharge
the accumulators and to operate the heated probe system.
The accumulators should be recharged when the instrument shows a
corresponding message (acoustical warning and display infor-
mation). The accumulators loading stand can be checked, looking at
the voltage information on the display (menu "Control"). The battery
warning is activated when the value „ACC.B“ is smaller than 6 V.
By 5,8 V the power operation via battery is no more possible. The
instrument must be further powered via internal charging unit.
The control module of the ecom-J2KN
pro
is powered by 3 nickel-
metal-hydride accumulators (type AA). In case of need, the accumu-
lators can be recharged by docking the control module to the basic
module.
Hereby 2 functions can be selected („Adjustments / „Internal“ /
„Reloading function“ / <OK>):
1. Recharging function ON (<F1> = YES):
- batteries slowly and carefully recharged
- recommended adjustment by frequent use
2. Recharging function OFF (<F4> = NO):
- batteries quickly recharged
- recommended adjustment by occasional use
Used accumulators c
an be returned to us or brought
to recycling stations of public waste disposal compa-
nies respectively accumulators selling stores!
Never use batteries, to operate the control
module of the J2KN

4. Radio communication basic / control module
Thanks to the detachable control mod-
ule the basic module can be monitored
wireless. The basic module can be un-
locked as follows:
1. Press to unlock.
2. Tip control module forwards
3. Release control module from basic
module
The information exchange between
control and basic module is performed
via radio transmission (868 MHz) with a
coverage of approx. 50 m (by free
sight). The quality of the radio transmis-
sion is documented by a bar indication
in the main menu of the instrument
(long bar = good radio communication).
By interruption of the radio
communication, an error message is
displayed. By persisting disturbances of
the radio communication, a cable
(option) can take over the transfer
(connection betwen socket DATA on
control unit and socket DATA on basic
module).
If the basic module is switched off and
the control module not, so the display
will show an error message inviting to
fix the control module in its docking
station (helps also not to forget the con-
trol module). Observe this order, quit
with <ESC> and finally switch off the
control module.

5. Data record
The multi-media card enables the storage of both punctual meas-
urements and data logger records.
The values of punctual measurements are written in a text file
(J2KDV.txt). Those of data logger records in a csv file (J2KDL-xx.csv
/ xx = records numbered consecutively).
Both file types have the same structure and can be imported respec-
tively opened in Excel. See chapter „Technical Data“ for data format
information. The files can be transferred on the PC using a card
reader. The following conditions must be fulfilled for using a multi-
media card:

8. Gas measurement
8.1. Gas analysis
After the 1-minute calibration phase, the instrument switches over to
the measurement mode. The gas measurement values can be
viewed on different display pages. Use the cursor keys to scroll the
pages.
With <F1> you can switch from the measured value display to a
menu or to „Standby“ selected before (see chapter “Adjustments”).
Possible menu options are: Soot... Oil trace, Data processing, Ad-
justments, Control, Fuel type, Eff. (C), Memory -> M, Pressure. Fur-
ther you can switch with <F1> from any menu back to the measured
value display.
With <F2> you can print and store the measured values into the in-
termediate memory at the same time.
With <F3> you can switch off the CO sensor, in order to protect the
sensor against too high concentrations. The automatic disconnection
will switch off the CO sensor at approx. 4000 ppm.
With <F4> you can switch from the measured value display to a
menu or to „Standby“ selected before (see chapter “Adjustments”).
Possible menu options are: Soot... Oil trace, Data processing, Ad-
justments, Control, Fuel type, Eff. (C), Memory -> M, Display values,
Pressure. Further you can switch with <F1> from any menu back to
the measured value display.

The position of the measured and calculated values (gas analysis)
on the display pages is free selectable (choose „Display values“ for
<F4> Hotkey). For alteration of the existing succession respectively
personal listing, proceed as follows:
-Press <F4> to activate the function.
-select the line with the cursor keys <up/down>,
-select the measured or calculated value with the cursor
keys <right/left>,
-repeat this procedure until all modifications are completed.
-Press <F4> to deactivate the function.
Position the sampling probe in the exhaust channel so that the ther-
mocouple is fully surrounded with the gas (see picture).
Perform the measurement in the core stream of the exhaust gas
channel (probe placed in the highest gas temperature area). A trend
indication for T.Gas easies the core stream search. As long as the
display shows a + symbol, the measured temperature increases, it
means the probe tip moves towards the core stream. If a - symbol is
displayed, pull the probe out of the core stream and the temperature
sinks. If no temperature change is shown for at least 3 seconds, so
the trend indication will be deleted.

, efficiency, losses, excess air and dew point are calculated val-
ues. They can only be calculated if realistic values for the basic pa-
rameters O
2
and temperatures are available. It must be ascertained
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 entered. This value cannot be determined by the ecom-
J2KN
pro
. If the gas temperature falls below the dew point (between
25 and 65 °C), ETA will be calculated with condensation. In the dis-
play (C) appears behind ETA.
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 at the sensors. This time period lasts approx. be-
tween 1 and 1.5 minute. For recording, printout and evaluation wait
until the values do not change anymore. If deviations higher than 2
ppm still occur by the gas values, they can be due to unstable pres-
sure conditions in the exhaust channel.
If the measurement values are stable
and the results can be printed out, press
the key <Record> (disc symbol) to
transfer the values in the intermediate
memory (caution: store gas analysis
and CO measurement values separate-
ly). The values are stored 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).

8.2. CO measurement (gas channel check)
For the technical check of gas-fired plants in regards of safety as-
pects the gas channel check called also CO measurement is used.
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 ho-
mogeneous because of the flow in of secondarily air and conse-
quently 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 oxy-
gen content would amount 0% by the same exhaust gas volume.
It is consequently the undiluted CO
content in exhaust gas. If the value indi-
cation is stable, press the key
<Memory> (disk symbol) to store the
result in the intermediate memory. If a
printout of the values should occur sim-
ultaneously to the recording in the in-
termediate memory, press <F2> (the
complete content 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 may be rise)
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 the key <Memory> (disk symbol)
to store the value in the intermediate
memory. If a printout of the values
should occur simultaneously to the re-
cording in the intermediate memory,
press <F2> (the complete content of the
intermediate memory will be printed
out).
8.4. Flow measurement (option)
This measurement can be done with a
pitot tube. At first the pitot factor of the
pitot tube must be entered („Adjust-
ments“ / „Internal“ / „Pitot factor“).
After connecting the pitot tube to the
instrument, the zero point of the sensor
can be set with <F4>. With <F1> the
cross section of the flow channel can be
entered (needed for calculation of the
flow rate). After the pitot tube is posi-
tioned in the flow channel, the display
shows the speed (m/s), the flow rate
(Nm
3
/h) and the differential pressure
(Pa). 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).
