EL-USB-1

Temperature Data Logger with USB Interface

This data loggermeasures and storesup to 16,382temperature readings overa -25 to +80°C (-13 to +176°F) range.
The user can easily set up the logging rate and start-time, and download the stored data by plugging the module
straight into a PC's USB port and running the purpose designed software under Windows 98, 2000 or XP. Data
can then be graphed, printed and exported to other applications. The data logger is supplied complete with a
long-life lithium battery, which will last for at least 1 year. Correct functioning of the unit is indicated by a
flashing red, green and orange LEDs. The data logger is protected against moisture to IP 67 standard when the
protective cap isfitted.

EL-USB-1

Temperature Data Logger with USB Interface

LED FLASHING MODES

EL-USB-1 features 2 LEDs.

- The first LED flashes orange (O) to indicate a problem condition on the EL-USB-1.

- The second LED flashes green or red (G/R) to indicate alarm level status.
It will flash red when the logged temperature has exceeded a Low or High alarm level.

By default latching is enabled, so the red LED will continue to flash, 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
notified that an alarm level has been exceeded, without the need to download the data from the logger.

Latching can be turned on via the control software. The red LED will then no longer continue to flash after the
logged temperature has returned to normal. Instead, the green LED will then flash.

The LEDs on EL-USB-1 will flash in one of the following ways, assuming latching is turned off.

O G/R

Green LED flashes twice every 10 seconds

- The data logger is not currently logging, but is primed to start at a later date and time.

Green LED flashes once every 10 seconds

- The most recently logged temperature is between the Low alarm and High alarm levels.

Green and Orange LEDs flash once every 10 seconds

- The most recently logged temperature is between the Low alarm and High alarm levels,
but the data logger's memory is full, so no more readings are stored.

NB: If latching is enabled, then a flashing green LED indicates that no alarm condition has ever been logged.

Red LED flashes once every 10 seconds

- The most recently logged temperature is equal to or lower than the Low alarm level.
(if latching is enabled, then the alarm condition may have been triggered a while ago)

Red and Orange LEDs flash once every 10 seconds

- The most recently logged temperature is equal to or lower than the Low alarm level
(if latching is enabled, then the alarm condition may have been triggered a while ago),
but the data logger's memory is full, so no more readings are stored.

Red LED flashes twice every 10 seconds

- The most recently logged temperature is equal to or higher than the High alarm level,
(if latching is enabled, then the alarm condition may have been triggered a while ago).

Red and Orange LEDs flash twice every 10 seconds

- The most recently logged temperature is equal to or higher than the High alarm level
(if latching is enabled, then the alarm condition may have been triggered a while ago),
but the data logger's memory is full, so no more readings are stored.

Orange LED flashes once every 60 seconds

- The battery is reaching the end of its useful life, as its voltage has dropped below 3.3V.

- Data logging continues until the battery voltage drops below 2.8V.

No LEDs flash

- The logger is not being used.

or

- The logger was logging, but has now shut down due to a flat battery (voltage has dropped below 2.8V).
Plug the data logger into the PC and run the control software to find out which condition applies.
