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!

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.

Bypass Switch (Pro IN)..Turn on/off fresh air bypass to purge

Info Screen (Pro Easy)....View diagnostic info on Control screen

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.

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.
