1. Important Things to Remember
The J2KN Pro meets the requirements of EPA
CTM-030 and CTM-034 and ASTM D-6522 test-
ing protocols for portable emission analyzers.
In order to receive accurate measurements,
please allow reading to stabilize
for at least 2 minutes.
The J2KN Pro is not suitable for continuous
emission testing. Please allow at least 10
minutes of fresh air purge for each hour of
testing.
The following substances may cause damage
to the electrochemical sensors:
Cleaning agents
Degreasers
Wax polishes
Adhesives
Formaldehyde
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 frequent use

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*

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

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
