After the 1-minute auto-zero phase, the instrument switches over to
the measurement mode. The gas measurement values can be
viewed on 4 display pages. Press up/down to scroll between the
pages.
(Note: To view readings with O2 correction, go to Adjustments ->
Ref. O2 and input the O2% correction (usually 3% or 15%). Then go
to Adjustments -> Units and change to undiluted %O2.)
Pressing <F1> goes to “Standby“ mode which turns the pump off. If
you want to change the F1 key, go to Adjustments->Internal->F1
Hotkey. You can set the F1 key to: Soot test, Data processing, View
memory, Display values, Fuel type, Efficiency (K), Internal, and Ad-
justments.
Press <F2> to print out the values simultaneously to their recording
in the intermediate memory.
Press <F3> to start the CO purge pump. This dashes out the CO
reading on the display and introduces fresh air to the CO sensor to
protect it from over ranging Note: The CO purge pump automati-
cally activates when the CO ppm limit is exceeded –usually set
at 4000ppm.
