Low Battery Level; Auto Power Off - Fluke DATAPAQ Tracker XL2 User Manual

Charging status is shown by the LED next to the charging socket: red when
charging is in progress, green when charging is complete. A full charge is
delivered within 2 hours. No light when the charger is attached indicates a
problem: there may be a connection problem or the battery may need
replacing.
New batteries – or ones which have been unused for several months – should
be charged for 24 hours before use. NiMH batteries discharge slowly even
when not in use and will need charging if left for more than three weeks.
Where batteries are too cold (below 0°C/-32°F), too hot (over 45°C/113°F) or
too deeply discharged, the charging system will automatically pre-condition
them before proper charging begins. Pre-conditioning (slow charging) takes
extra time, but if the battery is still being pre-conditioned (i.e. the logger is
showing a red charging LED) after 5 hours there may be a fault; contact
Datapaq.
The logger intelligently monitors the battery, ensuring it is never overcharged. Thus,
by leaving the charger connected to the electricity supply, the logger will always be
on charge and ready for use. This will not damage the battery or reduce its

Low Battery Level

When the battery's charge drops to 20% of the full level, this will be shown by
the flashing yellow battery status LED on the logger, and (if connected to the
PC) by the Insight software. When the battery is empty, the logger shuts down,
preserving data already gathered – and, when the data is downloaded, Insight
will give a warning that this has happened.
Auto Power-off
To conserve battery charge, the logger will power-off temporarily (e.g. LEDs
will stop operating) in the following situations:
• When it has been inactive for 5 minutes, whether or not it is connected to
the PC.
• Immediately it is disconnected from the PC if it does not contain data from
a previous run which has not been downloaded (e.g. after a reset or
download).
• When it has been indicating an error (alphanumeric display showing E1,
etc. – p. 21) for 5 minutes.
Any data contained in the logger's memory will not be lost.
