DATAPAQ TP3 Using Insight Software 53
Logger Defaults and Details
Defaults for several of the logger’s variables can be set using Insight. Select
Tools > Options > Logger (and click ‘Advanced’ for most features):
• Default number of probes.
• Model and identification number (serial number) of the logger.
• Calibration information, including enabling a warning for re-calibration and
setting options for applying logger correction. For details, see p. 33.
• Use of warning message and/or disabling of reset if the logger is hotter
than a specified temperature (d efa ul t 4 5°C / 113°F ) .
• Ability to display profiles of the logger’s internal temperature and/or battery
voltage for the run: these appear in the Graph and Analysis Windows as if they
are data from additional probes; battery voltage is shown on the graph’s right-hand
y-axis. Display of both is disabled by default: to enable, in Insight select File >
Properties > Advanced. Also, download of internal-temperature data from the logger
to the paqfile is disabled by default: if you wish to view this data, download must
be enabled in the Logger tab of the Global Options dialog before running the profile.
• Ability to download and display pre-trigger data (see below).
• Default (fixed) sample interval which cannot be edited in the Reset dialog
(p. 42). The value entered is subject to the maximum and minimum
permitted intervals (see p. 13).
• Frequency of the local electricity supply. Setting this correctly
increases the efficiency of the logger’s noise rejection, and thereby provides
more stable measurements: 50 Hz is most widely used, but 60 Hz is used in
North America, several countries in South America, and in Japan and Korea.
• Ability to include a marker within the data being gathered by pressing the
logger’s start button (see below).
• Disable stop button during a profile run. Thus, after logging is started, it
can then be stopped only by connecting the communications lead (if
necessary, disconnect then re-connect the lead) or by setting a stop trigger
(p. 44). Note that:
○ Setting this option does not prevent use of the stop button during
hardwired telemetry.
○ Setting this option prevents use of the stop button when the logger is in
multiple-run mode (p. 45) and is gathering data, but, when in multiple-
run mode but paused between runs, the stop button can always be used
to terminate multiple-run mode.
• The logger’s internal data-sampling rate can be reduced to a slower rate
in order to increase the amount of data which is averaged in creating a single
data-point. This option is disabled by default, but can be useful to reduce
issues with noise in the data.
For full details of using the dialog, see Insight’s online Help.
