Filters
Particulate filter (water trap filter)
Unscrew the cover of the water trap and check the particu-
late 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!

J2KN Pro Start-up
Make sure the probe is in fresh air when you
turn on the J2KN Pro.
1. Switch on the J2KN base unit and the remote control
unit. The Main Menu is displayed with 8 sub-menus:
- Gas analysis View gas readings & calculations
- Averaging Perform averaging tests
- Draft/Pressure Calibrate pressure sensor
- Soot Test Perform soot/smoke density test
- Automatic meas. Data logging onto memory card
(Pro Easy & IN) and set up auto-
matic test cycles (Pro IN only)
- Adjustments Modify J2KN settings
- Control Diagnostic info/Calibration mode
- Diagnostics (Only used with ECOM AK tool)
2. Select Gas Analysis and press <OK>
3. Press Up/Down to select Fuel Type
and press <OK>
1. Analyzer will complete auto-zeroing
of all sensors, except the O2 sensor
which is calibrated to 20.9%

Gas Analysis
If you change testing environments, let the
analyzer acclimate to the new ambient envi-
ronment, then power down and restart.
After the 1-minute auto-zeroing phase, the instrument switches
to Gas Analysis mode. The measurement values can be viewed
on 3 display pages: a zoomed in 4-line display and 2 full 9-line
displays. All line items are user-selectable (see Display Values
below). Press Up/Down to scroll between the pages.

Capturing Data on Memory Card (2GB max)
Data Logging in Timed Intervals
1. Go to Automatic Meas. > Save to MM
Card. This is the time interval that each
data point is recorded to the memory card
(min. 1sec, max 255sec). Input desired
amount in seconds and press OK.
2. Select Datalogger > “Start dl? Are you
sure?” > Press F1
3. Analyzer is now in Datalogging mode. The
blinking disk in the top right corner indicates that the analyzer
is currently logging data. Press to return to the main menu
and select Gas Analysis to view real-time measurements.
4. To complete data logging and save the file, press to return
to the main menu, go to Automatic Meas. > Datalogger >
“Finish dl? Are you sure?” > Press F1.
OR
Capturing Data Snapshots On-Demand
1. Go to Automatic Meas. > Save to MM Card and input 255.
2. Select Datalogger > “Start dl? Are you sure?” -> Press F1
3. Press to return to the main menu and go to Gas Analysis
to view real-time measurements.
4. Press 5 (disk symbol). You will see an X over the disk icon
in the top right corner. This is normal and expected.
5. When you are ready to capture the first data point, press 5
(disk symbol), wait 2 seconds, and press 5again. The
data point was captured during the 2 second interval.
6. Repeat step 5 for all desired data points.
7. To complete data collection and save the file, press to
return to the main menu, go to Automatic Meas., select
Datalogger -> “Finish dl? Are you sure?” -> Press F1.
Each data file will be saved separately as J2KDL-00, J2KDL-01, etc. Open in
Microsoft Excel. You can also import the data from the SD card into ECOM’s
free DAS 5 software to create formal reports.

Software Communication
If you need help with installation or operation of your DAS
or e-Comply software, please consult the User Manual for your
software product. If you are having trouble communicating
from the analyzer to a computer, please check the following:
Adjustments > Internal > RF Connect
Make sure it is in Remote setting.
Adjustments > Internal > USB
For both DAS and e-Comply, make sure the Baud rate is
38400 and the Protocol is Enhanced.
Adjustments > Internal > WLAN (if applicable)
If you have WiFi communication problems, refresh the WiFi
signal by selecting Auto Connect > F1. You will see the IP
address dash out and come back again. Note: You can’t con-
nect to both the software and mobile app simultaneously.
Adjustments > Internal > Bluetooth (if applicable)
For both DAS and e-Comply, make sure the Baud rate is
9600 and the Protocol is Enhanced. To reset the Bluetooth
signal on your computer, right-click on > Show Bluetooth
Devices > Right-click on BT connection> Remove Device. Now
click Add a Device and re-connect to the analyzer. PIN=1234
If communication issues persist, re-sync the remote & base
1. Place remote unit into cradle. Go to Adjustments >
Internal > RF Connect and select Standard.
2. The base and remote are now synced.
3. Change the RF Connect setting back to Remote.
4. The remote can now be used as normal.
If all else fails, do a hard reset of the analyzer:
1. Power down the analyzer.
2. Disconnect analyzer from AC power.
3. Open the battery drawer and disconnect the lead from the
battery (white plastic clip). Wait at least 1 minute.
5. Reconnect the battery, reconnect the power cord, and
restart analyzer. You have just completed a hard reset.
