Monitoring Electrodes Inlet Water drain J2KN Pro must be plugged in for the Peltier cooler to operate. Exhaust gas with a temperature above dew point is intro- duced into a spiralling gas path with a coated metal surface of good thermal conductivity. The hot gas radiates its heat to...
4. Gas Path Diagram Response Time After inserting the probe into the sample gas, there is a short delay before correct measurement values are dis- played. This is necessary for the gas to pass through the sampling system and build up a stable electrochemical reac- tion at the sensors.
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.
6. Radio Communication The J2KN Pro base unit communi- Unlock cates 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.

8. Emissions Measurement 8.1 Gas Analysis Calibrate the sensors before each emission test for best results. 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.
8.1 Gas Analysis (continued) Core Stream Search 8.2 % To obtain the most accurate gas 431 ppm 126 ppm sample, the end of the probe should be 65 ppm positioned in the center of the exhaust stream or the “core stream” where the Gas analysis thermocouple is fully surrounded with 25.11.07...
8.2 Printing Wait for the measurement values to stabilize for at least 2 minutes before printing the results. Quick Print The easiest and quickest way to print is to press <F2> for quick print, which immediately prints the measurement values currently on the screen.
To turn probe heating on, go to Adjustments -> Internal -> Probe heating -> F1 J2KN Pro must be plugged in for the probe heating function to activate. Allow 3 minutes for the probe to heat up before soot test.
9. Data Logging onto Memory Card (2GB max) Initial Set-up 1. Insert memory card (32MB to 2GB) into the top-right of the handheld display 2. Go to Automatic Meas. -> Save to MM Card. This is the time interval that each data snapshot is recorded to the memory card (min.
10. Averaging Tests The Averaging function allows you to take a sample of emissions data and compute an average over time. 1. Go to Averaging -> Select Meas. Time Averaging Start measurement 2. Input total measuring time in minutes or Meas.
11. Draft/Pressure A trend indication for the draft conditions in the exhaust channel is displayed in the Gas Analysis screen. Note that the pressure sensor tends to drift because of its sensitivity, and it is necessary to calibrate the sensor immediately before sam- pling to get an accurate measurement.

Set the Pitot factor for flow rate calculation. If the flow rate calculation is not needed, set Pitot factor to 0. If you are using a standard ECOM probe, set this to 0.93. (For more information on the flow measurement option, see 17. Flow Measurement with Pitot Tube.)
13. Control The electrochemical sensors change their output values over time based on frequency of use. The J2KN-Pro is pro- grammed to monitor the sensors and correct drifts. If the drifts and the correlated measurement errors increase, an er- ror message is displayed and it is time to change the sensor. The control menu displays the status of the sensors, batter- ies, radio quality, error count, number of times the J2KN-Pro has started up, and other analyzer information.
14. Maintenance Tips Only use sensors, filters, and filter media provided by ECOM. Do not use desiccant! 14.1 Filters Particulate filter (water trap filter) Unscrew the cover of the water trap and check the particu- late filter for greyness. Change it once the filter has a dark- ness of 4-5 on the soot chart scale.
14.1 Filters (continued) Ventilation filter The ventilation filter should be changed if the filter has a darkness of 2-3 on the soot chart scale. Use a screwdriver to pry open the filter holder from the slots on each side. Change the filter cartridge and refasten the filter holder.
14.3 Sensors (continued) The CO sensor is protected from exposure to high con- centrations 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 To change the printer paper, please follow these steps: 1.

16. How to Calibrate Sensors For best results, the calibration gas concentration should be as close to the expected levels of emissions as possible. Because each sensor is linear through a nominal range, one calibration gas concentration can be used for a reasonably wide range of emission levels.
