Measurement Scenario
An intermittent problem exists where, for short periods of time levels of SO2
intheueexceed300ppm.Thecauseoftheproblemisunknownanditis
expectedthatbyexaminingtheoverallproleoftheuegasesduringthe
fault a diagnosis will be possible.
The problem however may not occur for several hours and to analyse
it,readingsmustbetakenevery5seconds.ConguringInsighttolog
every 5 seconds for an extended period of time will cause excessive and
irrelevantdatatobecapturedmakingfaultdiagnosismoredicultandtime
consuming.
Solution
Insightisequippedwithatriggeringsystemthatenablestheusertodene
the conditions where data acquisition will take place. The data logging
settingsandthetriggersettingscanbeconguredthroughthesystem’s
menus, and the Lancom 4 analyser left to continuously monitor
1
the process.
When the fault occurs the trigger will start the data logging process every 5
seconds over the period of interest. The relevant data can then be reviewed
easily.

ThefollowingtabledetailstheprocedurerequiredtocongureInsightforthe
solution described above. Against each step is a cross reference to a section

1 Care should be applied when the Lancom analyser is used for continuous monitoring
over extended periods of time as reduced sensor life may occur especially where the
monitored gases are at high concentration levels.
