“Air free CO measurement”
The J2KN can be used to check CO levels in the gas stream, relative to a 0% O2 concentration. To
view this screen, press the UP or DOWN arrow key in the Gas measurement mode. A screen
similar to the one below will be seen.
The calculated value shown on the line
CO 0% corresponds to the measured
CO concentration if the oxygen
content was 0% in the gas stream.
To store the value, press the
key <Memory> (disk symbol) to store
the result in the intermediate memory.
To printout the values, press <F2>.
Oxygen check
The same type of measurement can be made for only measuring Oxygen. Access this screen by
