This standalone data logger measures and stores up to 16,382
temperature readings over a -35 to +80°C (-31 to +176°F) range. The user can easily
set up the logging rate and start-time, and download the stored data by plugging the data logger
into a PC’s USB port and running the purpose designed software under Windows 2000, XP and Vista (32-bit).
Data can then be graphed, printed and exported to other applications. The data logger is supplied complete with a
long-life lithium battery which can typically allow logging for 1 year. Correct functioning of the unit is indicated by ashing red, green and
orange LEDs. The data logger is protected against moisture to IP67 standard when the protective cap is tted.

LED FLASHING MODES
EL-USB-1 features 2 LEDs.
• The rst LED ashes green or red to indicate alarm level status.
• The second LED ashes orange to indicate a problem condition on the EL-USB-1.
It will ash red when the logged temperature has exceeded a Low or High alarm level. By default hold is disabled. In this mode the
red LED will no longer continue to ash after the logged temperature has returned to normal from an alarm condition.
Hold can be turned on via the control software. In this mode the red LED that indicates an alarm condition will continue to ash, even
after the logged temperature has returned to normal. The red LED will effectively have latched into its alarm condition. This feature
ensures that the user is notied that an alarm level has been exceeded, without the need to download the data from the logger.
