DATAPAQ TP3
Pre-trigger Data
If a temperature trigger (see p. 43) is used to start data-logging, the logger
also records data before this point is reached. The most-recent c. 60 of these
data-points are retained by the logger. You can download this pre-trigger data
by setting a default (see above), and it will then form part of the temperature
profile, falling before the zero time point.
If the logger does not reach the temperature required to start data-logging,
Insight will always download the pre-trigger data, in order to aid the user in
determining why triggering did not occur.
Marking Events in Real Time
If the logger is accessible during a profile run (i.e. if using telemetry), it is
possible to include a marker at any point within the data, while it is being
gathered, by pressing the logger’s start button (the logger-status red LED
will flash once). When the data is displayed by Insight, it will show a vertical-
line memo at that point in the data, and the memo’s text and format can
subsequently be edited. Such markers can also be added in real time by using
Insight. For details, see Insight’s Help system: Introduction > Using Memos.
This feature is disabled by default. To enable, in Insight select Tools > Options >
Logger > Advanced.
For further features of the Insight software – particularly data analysis and the use
of process files – see the online Help system
