LED FLASHING MODES
EL-USB-4 features a red and a green LED.
The LEDs on an EL-USB-4 will flash in one of the following ways, assuming alarm hold is turned off (exact timings to
be confirmed).
By default hold is disabled. In this mode the red LED will no longer continue to flash 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 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.
