3. Peltier Cooler
J2KN Pro must be plugged in for the
Peltier cooler to operate.
Exhaust gas with a temperature above dew point is introduced into a spiralling gas path with a coated metal surface
of good thermal conductivity. The hot gas radiates its heat to
this metal coating, which is thermally connected to a Peltier
element and a second metal body with cooling ribs and ventilation slots. The flow thru the Peltier element creates a heat
transfer from WARM to COLD and this takes the heat from
the metal coating and transfers it to the outer cooling body.
The heat is then released to the surrounding air via a ventilation fan.
Condensation forms when the gas temperature drops below dew point. This moisture drains into the water trap bowl
and is pumped out by a peristaltic pump when the water
reaches a high enough level to link both monitoring electrodes.
The high speed pump allows for enough flow to avoid excess exposure time between the gas sample and water, so
that drop-out reactions (for example, NO2+H2O > H2NO3) do
not occur, which is necessary for measurement accuracy.

4. Gas Path Diagram
Response Time
After inserting the probe into the sample gas, there is a
short delay before the values start changing since the gas
has to pass through the sampling system. This is referred to
as response time, and it usually takes about 4-6 seconds for
the readings to start to change. Since the CO sensor has an
elongated gas path with the NOx/SOx filter (see diagram),
the response time for the CO is approximately 10 seconds.
Stabilization Time
Different from the response time is the stabilization time.
This is the time it takes for the sensors to build up a stable
electrochemical reaction in the electrolyte solution, and it
usually takes about 60-90 seconds for the readings to stabilize. NO2 readings may take slightly longer. For this reason,
wait 2-3 minutes for the readings to stabilize before printing
or recording emission results. Minor drifting of a few ppm can
be caused by minor pressure changes and may be negligible.
*All times listed here are based on using a 15ft sample line*
Page 11
5. Power Supply
The J2KN Pro base unit has an internal power supply, and
it is recommended to always run the unit on AC power. For
testing locations where an AC plug-in is not available, the
instrument can be operated from 6-8 hours on battery power
when fully charged. Connecting the J2KN-Pro to AC power
charges the battery and is necessary to operate the Peltier
cooler and heated probe.
When the battery level gets low, the analyzer will start to
beep and display a low battery warning. The voltage reading
on the battery is displayed in the Control screen. The warning is activated when the charge drops below 6 V. When it
reaches 5.8V, the battery charge is not sufficient to power
the unit.
Only use batteries supplied by ECOM.
Contact ECOM with any questions.
The J2KN remote control unit is powered by 3 nickelmetal-hydride batteries (type AA). These batteries are recharged by docking the remote control unit onto the J2KN
base unit. To change the settings for recharging these batteries, go to:
Adjustments > Internal > Reload function > OK
1. Recharging function ON (<F1> = YES)
- Batteries slowly and carefully recharged
- Recommended for frequent use
2. Recharging function OFF (<F4> = NO)
- Batteries quickly recharged
- Recommended for occasional use
- Note: Battery run-time is reduced on quick charge!
1. Charge the battery after each use
2. Always store unit with fully charged battery
3. Charge the battery at least once a month if
not in use
Page 12
6. Radio Communication
The J2KN Pro base unit communicates wirelessly to the remote display
unit via radio transmisision. To unlock
the remote control unit, press on the tab
to unlock and release from the cradle on
the base unit.
The information exchange between
the remote control and base unit is
performed via radio transmission (915
MHz) with a coverage of approximately
100ft by free sight. The quality of the
radio transmission is documented by a
bar indication in the Main Menu.
If the J2KN base unit is switched off
and the remote control unit is on, the
display will show a message telling the
user to place the remote control unit
into the docking station (see below).
Troubleshooting Communication Issues
If there is interruption of the radio communication, an error
message is displayed (see below right). If this occurs frequently,
it may be necessary to re-sync the remote to the base unit:
1. Place remote unit into cradle
2. Go to Adjustments > Internal > RF
Connect > Standard > OK
3. The base and remote are now synced
4. Go to Adjustments > Internal > RF
Connect > Remote > OK
5. The remote can now be used as normal

8.1 Gas Analysis (continued)
Heated Probe
If you are testing in a cold temperature environment, you
may require a heated probe so that condensation does not
form (or freeze) in the probe or probe grip. To turn on the
heated probe, go to Adjustments>Internal>Probe heat-
ing>F1. Remember to turn it off when the probe is not in
use, and allow the probe to cool before placing it in the case.
Core Stream Search
To obtain the most accurate gas
sample, the end of the probe should be
positioned in the center of the exhaust
stream or the “core stream.”
A + or – symbol displays in the core stream box (see figure above), indicating a trend towards positive or negative
temperature. As long as the display shows a + symbol, the
measured temperature is increasing and the probe tip is
moving towards the core stream. If a - symbol is displayed,
the measured temperature is decreasing and the probe tip is
past the core stream. Pull the probe back slightly to reach
the core stream, and adjust the probe cone so that the probe
is firmly in place.
Calculated Values
Calculated values include CO2, efficiency, losses, and excess air and are defined only when realistic values for O2 and
temperature are available. Otherwise, the values will dash
out on the display. For the calculated values to appear on the
display, the O2 concentration must be less than 20.5%

12. Frequently Asked Questions
Where do I find important instrument information?
How long is the life span of the
sensors?
Which sensors can I exchange?
The instrument shows the error
message “O2 sensor 0 mV“
The instrument shows the error
message “T-Gas“ or “T-Air“
The instrument shows wrong or
inaccurately CO2 values
Can I change the printout?
In the Control screen, all important instrument information is shown (e.g. battery voltage, sensor values, serial number, next service date, operation hours, etc.).
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 or insufficient purging. The life span for these sensors
is on average 3 years. The life span of the O2
sensor is independent of the operating hours
and amounts to approximately 2 years.
The following sensors are exchangeable:
- O2 sensor
- CO sensor (pre-calibrated available)
- NO sensor (pre-calibrated available)
- NO2 sensor (pre-calibrated available)
- SO2 sensor (pre-calibrated available)
The O2 sensor must be changed.
Note: The error messages can be bypassed by
pressing . Calculations that rely on these
temperatures will not display.
Possible reasons could be:
- Cable is broken (at the plug)
- T-Air sensor error – check all connections
- T-Gas sensor error – check all connections
- Thermocouple is defective
Possible reasons could be:
- O2 is defective (CO2 values are calculated
from O2 value)
- Pump is not working correctly
- Air leakage in the gas path
- Peltier cooler is clogged
Yes, go to Adjustments > Internal > Printout

16. Maintenance Tips
Only use sensors, filters, and filter media
provided by ECOM. Do not use desiccant!
16.1 Filters
Particulate filter (water trap filter)
Unscrew the cover of the water trap and check the particulate filter for grayness. Change the filter when it is dark gray.
Tip: use the elbow piece as a reference since it is dark gray.
In-line smoke filter
The round in-line smoke filter should be checked periodically
for grayness. Change the filter when it is dark gray. Tip: use
the elbow piece as a reference since it is dark gray.
NOx/SOx filter
The CO sensor has an independent gas path (see 4. Gas
Path Diagram) which includes a potassium permanganate
chemical filter for filtering SO2 and NOx from the gas sample.
Color change: purple -> brown -> grey-> white
Filter media should be changed once it has turned grey!

16.2 Sample Line and Probe
The sample line and probe should be cleaned regularly to
release particle deposits and to prevent early wearing due to
corrosion.
To clean the hose, disconnect from the analyzer end and
the probe end, blow out the line with short bursts of air from
an air compressor, and hang up to dry overnight so that excess water may drain out.
16.3 Sensors
During the J2KN-Pro start-up procedure, each sensor is zeroed using fresh air as the reference point, except for the O2
sensor which is calibrated to 20.9%. The status of each sensor is permanently monitored by the instrument. The sensor’s
life span is shortened by the exposure to high concentration
gases above the measurement range. The output values of
the sensors should be in the range of:
O2 OO/105 (white) 11000 mV to 13000 mV
O2 5FO (black) 17000 mV to 24000 mV
All others -100 mV to +100 mV
If an error message is displayed during the start-up phase
and cannot be cleared despite several restart attempts,
please call an authorized service center for troubleshooting
advice.
Slots
Page 30
16.3 Sensors (continued)
The CO sensor is protected from exposure to high concentrations by the automatic CO bypass pump. If the limit
value of 4000 ppm is exceeded, a second pump switches on
and purges the sensor with fresh air.
14.4 Printer Paper

Step 12: Calibrate your new CO sensor using certified calibration gas
Page 34
18. How to Calibrate Sensors
For best results, the calibration gas concentration should be as
close to the expected levels of emissions as possible. However,
because each sensor is linear through a nominal range, one calibration
gas concentration can be used for a reasonably wide range of emission
levels. For applications with extremely low or extremely high levels of
emissions, you will need to tailor your calibration gases accordingly.
Fully charge analyzer:
Place unit on charge the night before you plan to use analyzer to
ensure full charge of battery.
Initiate analyzer:
1. Attach T-gas thermocouple, sample line, and power cord.
2. Switch on analyzer.
3. Select Gas Analysis on main menu.
4. Select Fuel Type, press OK.
5. Allow instrument to complete self-calibration/auto-zero sequence.
Put analyzer in calibration mode:
1. Press to return to main menu and go down to select Control.
2. While in the Control screen, swipe calibration magnet over the Cal
Magnet sticker, located at bottom left of keypad.
3. The analyzer is now in calibration mode. You will see the sensor
readings with a cursor that you can move up and down. The O2%
reading is located at the bottom of the screen.
Check for air leaks:
1. To check for air leaks, you must introduce a gas with zero O2%
through the entire sample train. This is necessary to check that the
system has no leaks to atmosphere. We recommend NO gas
balanced in N2 because you can check for air leaks and calibrate the
NO sensor at the same time (2 birds, one stone). If you have a
CO/NO mix balanced in N2, you can use this as your leak check gas
as well (3 birds, one stone).
2. To connect the calibration gas cylinder to the analyzer, use one of
the following three set-ups:
Page 35
18. How to Calibrate Sensors (continued)
On-Demand Regulator: (Recommended) Use an on-demand
regulator which uses the analyzer pump draw to establish flow.
Connect the on-demand regulator to the sample train and open
the cylinder valve. The analyzer pump controls the flow as to not
over or under pressurize the sensors.
Adjustable Flow Meter: Connect an adjustable flow meter to the
sample train and measure the pump draw. Then connect the gas.
Use the cylinder valve for course adjustments and the flow meter
for fine adjustments to match the flow of the pump draw.
Vented Flow Meter: Connect a vented flow meter to the sample
train and connect the gas. Open the cylinder valve until a small
amount of gas is exiting through the vented flow meter. This
prevents air from entering system and allows pump to control
internal pressure within analyzer.
3. After you have connected the gas to the analyzer, watch the O2
reading until it is 0.0%. If it does not reach 0.0%, you may have
an air leak. Troubleshoot the source of the leak and correct it. It is
also possible that the system is tight but your O2 sensor is aged.
4. Do not proceed to calibrate the analyzer until you have verified that
the O2 reading goes down to 0.0%!
Calibrate your analyzer:
1. Apply the gas and wait for the reading to stabilize. (If you used a
cal gas for the leak test, the readings should be stabilized already.)
2. After the reading has stabilized, you may calibrate the sensor. To
calibrate, move the cursor beside the target sensor and press OK.
Input the concentration value from the gas cylinder and press OK.
3. The reading will change to the calibration gas value. Watch the
reading to make sure it doesn’t drift. If it does, wait until it stabilizes and re-calibrate. If it keeps drifting, the sensor may be aged.
4. After you have verified calibration, disconnect the gas.
5. Repeat steps 1-4 for each sensor.
6. After the calibration is complete, allow the analyzer to flush with
fresh air for 5 minutes or until readings are below 10 ppm.
Page 36
19. Flow Velocity Measurement (Option)
Stack flow or exhaust gas flow can be measured by the
J2KN-Pro using a special flow probe. If you are using a standard
ECOM probe, set this to 0.93.
First, the Pitot factor must be entered in the Adjustments
menu to get the correct flow rate calculation. Input 0.93 for the
Pitot factor if you are using a standard ECOM probe. To do this,
go to:
Adjustments > Internal > Pitot factor
After connecting the Pitot tube to the
analyzer, go to Flow Measurement
Press <F4> to set the zero point of the
flow sensor.
Press <F1> to input the cross section
of the stack or exhaust stream, which
is required for the flow rate calculation.
Position the Pitot tube in the stack or
exhaust stream.
The display will show the speed (m/s),
flow rate (Nm3/h) and differential pressure (Pa). After the values have stabilized, press <F2> to print the results.
*Call ECOM at 877-326-6411 if you would like the flow measurement
option added to your J2KN-Pro. You will have to get a return authorization number and send the analyzer to our service department in Gainesville, Georgia, USA.
