Page 10: Gas Path Diagram
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. -
Page 11: Power Supply
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. -

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. -
Page 15: Gas Analysis
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. -

13. 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. -

Page 27: Control
15. 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. -
Page 28: Maintenance Tips
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 particu- late filter for grayness. Change the filter when it is dark gray. -
Page 29: Sample Line And Probe
16.1 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. -

16.3 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. -

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. -

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. -
