increments, and is set in windows (8) to (11), and (13). The measured
data may be displayed unfiltered (“Direct“), or filtered using either the
sliding average filter or the standard filter.
A significant advantage offered by the “CONT“ mode is the ability to
choose different integration times for the main and pre-chamber (AIC de-
termination) measurements. The latter time is the same as that during a
calibration, and is set in window (6). (See also section 5.2.2.2 (5)). More
details of the “Continuous measuring mode“ are given in Appendix A5.
The different modes appear by pushing the “NO“ key repeatedly. The
desired mode is activated with the “YES“ key.
To return to the main menu (“MAIN“-window (2)), press the “MENU“
key. Press the “MEAS“ key to move to the “MEAS“-window (1)).
Caution:
It is important when choosing a mode to confirm the selection by en-
tering “YES“ before leaving this window. Otherwise the previously
used mode will remain selected.
