In case of battery operation the power is reduced
(output temperature 8 – 10 °C)!
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 receptacle 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
(NO2+H2O > H2NO3) do not take place.
At the cooler outlet the gas has a temperature of ca. 5 °C with a relative saturation of nearly 100 % relative humidity (corresponds to a
3
water steam content < 7 g/m ).

3. Power supply
Used accumulators can be returned to us or brought
to recycling stations of public waste disposal companies respectively accumulators selling stores!
pro
The basic module of the ecom-J2KN
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 information). 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.
Never use batteries, to operate the control
pro
module of the J2KN !
pro
The control module of the ecom-J2KN is powered by 3 nickelmetal-hydride accumulators (type AA). In case of need, the accumulators 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

4. Radio communication basic / control module
Thanks to the detachable control module the basic module can be monitored
wireless. The basic module can be unlocked as follows:
Unlocking
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 transmission 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 control module). Observe this order, quit
with <ESC> and finally switch off the
control module.

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.

CO2, efficiency, losses, excess air and dew point are calculated values. They can only be calculated if realistic values for the basic parameters O2 and temperatures are available. It must be ascertained
that:
O2 < 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 ecompro
J2KN . If the gas temperature falls below the dew point (between
25 and 65 °C), ETA will be calculated with condensation. In the display (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 electrochemical reaction at the sensors. This time period lasts approx. between 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 pressure conditions in the exhaust channel.

8.2. CO measurement (gas channel check)
For the technical check of gas-fired plants in regards of safety aspects 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 homogeneous because of the flow in of secondarily 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 value indication is stable, press the key
<Memory> (disk symbol) 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 content of the intermediate

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 („Adjustments“ / „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

value for the chimney draught will not be stored together with the gas
values while pressing the key <Memory>.
Indeed the difference pressure sensor tends to drifts because of its
sensibility and, for an exact measurement it is consequently advised
to re-calibrate the sensor immediately before sampling and documenting the value.
Access the menu while selecting the
sub-menu "Pressure". The current
value is displayed as well as the instruction to adjust the zero point of the sensor. Release hereto the draught hose
from the instrument for a short moment
and press <F4>. The sensor is herewith
re-calibrated.
Fix the draught hose again. The display
shows the exact measurement value
which can be stored while pressing

9. Mean Value Measurement
By mean value measurement function measurements can be taken
in an adjustable time frame and mean values can be calculated.
Should the several measurement values or the mean value result be
stored a storage place has to be selected as described in chapter 7.
If the function “Store” is activated, based on this storage place all
measurements will be written consecutively on the next storage
places. If the function “Store” is not activated, the mean value result
can be stored on MMC with <Print> / „Memory -> M.
After run through fresh air calibration
the menu point “Mean value” can be
chosen. Before the mean value measurement can be started the settings for
“Meas.time”, “Scanning”, “Printer”
and “Storage” should be checked and
if necessary be changed. The meanings
are:
-Meas. time = Time frame in which the
mean values will be calculated
-Scanning = time between the measurements taken for mean value calculation
-Printer = logging of measurements
taken for mean value calculation
-Store = all measurements for mean
value calculations will be stored

12.2. Automatic measurement (option)
pro
The configuration of the ecom-J2KN with operation securing, self
regulating additional components like the condense trap, the gas
cooler and the magnetic valve technique permits even a long term
operation of the instrument. By setting time intervals for the measurement the instrument switches autonomously to fresh air purge
after the measurement phase (gas will be sucked via the connection
fresh air) and operates a calibration phase for the sensors.
This cycle repeats itself until the automatic measurement will be finished. For
setting the time intervals select from the
menu “Data processing” the menu
item “Automatic measu.”. The time
intervals have following meanings:

12.3. Data logger
Here a Data logger record (“Data logger” and key <OK> / on top
right on the display appears the disk symbol) can be started or finished (just available when using the multi-media card). With
<Memory> you can interrupt and continue the record (only in gas
analysis). For each recording one file will be written on the card. The
files will be numbered consecutively (J2KDL-00.csv, J2KDL-01.csv
and so on) and can be transferred to PC with a card reader. The
length of a dataset is 500 byte which means that on a 32 MB card
64000 measurements could be recorded.

13.3. 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.

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 entered. Hereto proceed as
follows:
- open respective window with <OK>
- input figures using numerical function
of keys
- confirm input with <OK>

14. Maintenance tips
Do not use other sensors or feelers from other manufacturers otherwise the TÜV approval
will not be valid anymore!
To secure the accuracy of your measuring instrument we recommend the annual check by an authorized ecom partner. In the case
of strong demand (e.g. permanent several hours of measurement
per day, rough conditions etc.) shorter intervals between checks
should be selected - please contact your ecom partner. All ecom
partners are listed under www.rbr.de.The following advices will be of
help for the daily check and maintenance of single parts or assemblies:
Service made by service centres not authorised by
rbr-Messtechnik GmbH will result in a complete and
immediate lost of any warranty!
Fine dust filter (condensate trap/gas cooler)
Screw off the cover of the condensate trap/gas cooler and check the
state of the particle filter. Change it once the filter has a grey colour
(number 2-3 of the soot comparison scale).

Ventilation filter
The ventilation filter should be changed, if the filter is grey colored
(number 2-3 of the soot comparison scale). Remove for this the filter
holder with the help of a screw driver (recesses on the right of and
left side). Change the filter cartridge and fasten the filter holder.

Sensors
The sensors get calibrated with the reference gas fresh air by each
switch-on procedure. The state of the sensors is permanently controlled by the instrument. New sensors age along the operation period because of the wearing of the reagents (oxygen sensor) and due
to soiling respectively exceeding concentrations beyond the nominal
measurement range (toxic sensors).
The output values of the sensors are (enter menu "Control"):
approx. 12000 mV
O2
Others 0 mV (+/- 150)
If an error message is displayed during calibration and cannot be
eliminated despite several calibration phases, so the instrument must
be checked by a qualified and authorised service centre. The oxygen
sensor must show a value >7000 mV, otherwise it must be changed
by an authorised service centre.
The CO sensor is protected against overload by the internal programme. If the limit value of 4000 ppm is exceeded, a second pump
switches on and flows the sensor with fresh air.

ecom-J2KNpro
SO2/NOx filter
In the tubing leading to the CO sensor on the top of the instrument
there is a chemical filter for filtering SO2 and NOx out of the flue gas.
The filter material is manganese-4-oxide granules and should be
changed once it has turned grey (colour change: pink> brown>
black> grey> white).
Probe and hose
Depending on the frequency of use, probe and hose should be regularly cleaned in order to release particle deposits and to prevent early
wearing due to corrosion.
-Release the connections at the instrument and at the probe
grip to free the hose.
-Clean the hose (flow warm water in then dry respectively blow
water drops out).
Change printer paper roll
-Release the printer cover.
-If necessary, extract the paper rest out of the printer
("Adjustments"/"Paper feed"/<OK>).
-Remove the printer shaft and place the new paper roll on the
printer shaft.
-Insert the paper end in the slot (future printed side must be ahead).
-Press ("Adjustments"/"Paper feed"/<OK>) to transport ± 10 cm
paper thru the printer.
-Place the printer shaft back in the fixation.
-Insert the paper thru the cover of the printer compartment.
-Close the printer compartment while fixing the cover.

16. FAQ
Where do I find important instrument information?
IIn the menu „Control“ all important instrument informations are shown (e.g. accu voltage, sensor values,
unit number, next service date, operation hours etc.).
With the arrow keys stands you can switch to the
second page.
How long is the life span of the
sensors?
The life span depends on the operating hours and
the instrument equipment. The life span of the toxic
sensors (CO, NO, SO2, NO2) is affected by high gas
concentrations and a not sufficient purging. The life
span for these sensors amounts to on the average
between 4 and 6 years. The life span of the O2 sensor is independent of the operating hours and
amounts to approx. 2 years.
Which sensors can I exchange?
The following sensors are exchangeable:
- O2 sensor
- CO sensor (pre-calibrated)
- NO sensor (pre-calibrated)
- SO2 sensor (pre-calibrated / only together with
CO sensor
The instrument shows the error
message „O2 sensor 0 mV“!
The sensor must be renewed.
The instrument shows the message „Check required“!
This message appears automatically every 12
months or after 250 operating hours. Note: This is a
recommendation to let check the instrument. The
instrument is however still ready for use.
The instrument shows the error
message „T-Gas“ or „T-Air“!
Possible reasons could be:
- Cable is broken (at the plug)
- T-Air sensor is broken
- Thermocouple is broken
- Cable is defective
Note: The error messages can be ignored at the
J2KNpro by pressing „OK“. Calculations that depents
on these temperatures are not implemented.
The instrument shows wrong or
inaccurately CO2 values!
Possible reasons could be:
- O2 is defective (CO2 values are calculated from
the O2 values)
- Pump is not working correctly
- Leakage in the gas way
- Condensate trap / gas cooler is clogged
ecom-J2KNpro

My instrument cannot be
switched on!
- Please check the mains cable
- Please check the fuse
- Please check mains connection (Plug socket
switched on?)
- Please load the accumulator min. 8 hours
(Accumulator could be over-discharged)
My instrument does not print!
Please check whether the printer paper is correctly
inserted. The thermal printer writes only on the thermally sensitive side. Please use always the correct
paper for the printer, you will prevent defects at the
printer. Please make sure that the printer is clean (no
chads in the drive).
Can I change the printout?
You can change the printout (Menu: Adjustments).
Hint: If you have several instruments of the same type, you can locate an error by
exchanging the accessories (probe, hose, temperature sensor etc.).
If further questions or problems should arise, please contact the next authorised service centre.
