2.9 Printing
The easiest way to make a print-out of the measured values displayed by the ECOM J2KN, is to
simply press the F2 / #2 key. The printer will start and all measured and calculated values will be
printed on the tape. If you wish to store only one reading for later print-out, you can press the

2.10 Draft / Pressure Measurement
The ECOM J2KN is equipped with a high quality piezoresistive sensor for differential pressure
measurements that are used to measure stack draft or pressure.
To perform the draft measurement, press the Menu key
to bring up the Main Menu. Select Draft
Measurement. The pump will shut off and the display will read:
Remove the draft / pressure connection from the analyzer, and press F4 to “zero” the pressure
sensor.
Re-connect to either the draft inlet or pressure inlet and allow 15 seconds for reading to stabilize and
show the exact value for draft in inches of water from 0 to +/- 40.00 inches. Press the
key to
store the draft reading, then press
to return to the main menu, select Gas Measurement, then
OK. To return to gas measurement function. The Draft reading is now stored in memory and will be
printed on the next print-out.
2.11 Soot – Oil Trace Test
To begin the Soot measurement, press the
key
to main menu. Select the Soot. Oil Trace
option, and press OK. The pump will stop. Depress the trigger on the pistol grip probe to insert the
Soot test paper disk in the slot. Release the trigger. Re-insert probe into the exhaust stack being
measured. Press the
OK
to begin the Soot measurement. The pump will re-start and draw 1.62 liters
of exhaust through the Soot paper. (You will see the 1.62 liters count-down on the display). When the
countdown is complete, depress the trigger on the probe to remove the Soot paper. You can now
determine the Soot level by comparing the Soot spot with the included Soot chart. The results (0.0 –
9.9) can now be entered via the keypad. This value will be stored and printed on the next test print.
Up to 3 Soot test can be entered, and the instrument will print all three and calculate the average
Soot test value.
