Over-Temperature Protection; Hardware Reset - Fluke DATAPAQ Tracker XL2 User Manual

Over-temperature Protection

The XL2 and the Insight software work together to reduce the likelihood of
corrupt or inaccurate data being recorded due to the logger's internal
temperature being too high. The logger measures its internal temperature
within the Transducer Interface; the internal temperature of the MemoryPaq is
not monitored.
• Insight can be instructed to show a warning message if a reset is
attempted (p. 46) when a currently connected Transducer Interface is
above a specified temperature (default 45ºC/113ºF); see p. 61.
• Insight can be instructed to prevent a reset when a currently connected
Transducer Interface is above a specified temperature (default 45ºC/113ºF);
see p. 61.
• The logger will not start logging if the Transducer Interface is above
45ºC/113ºF.
○ Error E1 (p. 21) will then show when the Transducer Interface is
connected to the MemoryPaq.
○ The logger will continue to check the internal temperature, and, if the
temperature drops to 45ºC/113ºF during the next five minutes, logging
will start; if the temperature stays above 45ºC/113ºF for 5 minutes, the
logger will power-off.
○ Disconnecting and reconnecting the MemoryPaq and Transducer
Interface will cause the internal temperature to be checked again for
5 minutes.
• If the logger's internal temperature exceeds 85ºC/185ºF, it shuts down,
preserving data already collected. When the data is downloaded, Insight will
give a warning that this has happened.
The logger records its internal temperature during a profile run. For access to this

Hardware Reset

Resetting the logger is normally done using the Insight software (p. 46), but, in
the event of a serious internal logger error, reset can be done without
attaching the logger to a PC. The reset parameters will be restored to the
factory defaults:
• Sample interval: 5 s.
• Trigger mode: plug-and-go.
