Lascar EL-USB-1 User manual

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.

Lascar’s EasyLog USB control software is supplied free of charge with each data logger. Easy to install and use, the control software runs
under Windows 2000, XP, Vista & 7. The software is used to set-up the data logger as well as download, graph and export data to Excel.
The software allows the following parameters to be congured:
• Logger name (up to 16 characters)
• ºC or ºF
• Logging Rate (10s, 1m, 5m, 30m, 1hr, 6hr, 12hr)
• High and low alarm levels
• Start date and time
The latest version of the control software
may be downloaded free of charge from

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 notied that an alarm level has been exceeded, without the need to download the data from the logger.
Green double ash
The data logger is not currently logging, but is primed to start at a later date and time (delayed start).
Green single ash
The data logger is currently logging. No alarm.
Green and Orange single ash
The data logger is full and has stopped logging. No alarm.
Red single ash
The data logger is currently logging. Low alarm.
Red and Orange single ash
The data logger is full and has stopped logging. Low alarm.
Red double ash
The data logger is currently logging. High alarm.
Red and Orange double ash
The data logger is full and has stopped logging. High alarm.
Orange single ash
The battery is running low as its voltage has dropped below 3.3V. Data logging will continue until the battery
voltage drops below 2.8V.
No LEDs ash
The data logger is stopped, the battery is empty or there is no battery

DIMENSIONS
All dimensions in mm (inches)
BATTERY REPLACEMENT
We recommend that you replace the battery every 12 months, or prior to logging critical data.
The EL-USB-1 does not lose its stored readings when the battery is discharged or when the battery is replaced; however, the data logging
process will be stopped and cannot be re-started until the battery has been replaced and the logged data has been downloaded to a PC.
Only use 3.6V 1/2AA lithium batteries. Check with your supplier that the battery you are ordering is ‘press t’ and is not tted with solder
tags. Before replacing the battery, remove the EL-USB-1 from the PC.
Note:
Leaving the EL-USB-1 plugged into the USB port for longer than necessary will cause some of the battery capacity to be lost.
WARNING
Handle lithium batteries carefully, observe warnings on battery casing. Dispose of in accordance with local regulations.
