HOLDOFF also prevents DAS measurements from being made at certain times when
the quality of the analyzer’s O
3
measurements may be suspect (e.g. while the instrument
is warming up). In this case, the length of time that the HOLDOFF feature is active is
determined by the value of the internal variable (VARS), DAS_HOLDOFF.
To set the length of the DAS_HOLDOFF period, see Section 5.8.
7.4.8. THE COMPACT REPORT FEATURE
When enabled, this option avoids unnecessary line breaks on all RS-232 reports. Instead
of reporting each parameter in one channel on a separate line, up to five parameters are
reported in one line.
The COMPACT DATA REPORT generally cannot be accessed from the standard
DASfront panel menu, but is available via the instruments communication ports by using
APICOM or the analyzer’s standard serial data protocol.
