LED FLASHING MODES
EL-USB-TC features 2 L EDs.
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 levelhas been exceeded, without the need to download the data from the logger.
Latching can be turned off 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 flash.
The LEDs on the EL-USB-TCwill flash in one of the following ways:
- The first LED flashes orange (O) to indicate a problem condition on the EL-USB-TC.
- The second LED flashesgreen or red (G/R) to indicate alarm level status.
Itwillflash red when the logged temperature has exceeded a Low orHigh alarm level.
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,
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.
NB: If latching is enabled, then the alarm condition may have been triggered a while
Red and Orange LEDs flash once every 10 seconds
- The most recently logged temperature is equal to or lower than the Low alarm level,
NB: If latching is enabled, then the alarm condition may have been triggered a while ago.
Red LED flashes twice every 10 seconds
- The most recently logged temperature is equal to or higher than the High alarm level.
NB: 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,
NB: If latching is enabled, then the alarm condition may have been triggered a while ago.
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.
- The logger was logging, but has now shut down due to a flat battery (voltage has dropped below 2.8V).
