LED FLASHING MODES
EL-USB-CO300 features a red and a green LED.
The LEDs on an EL-USB-CO300 will ash in one of the following ways, assuming hold of the warning threshold has been turned off in the
EL-WIN-USB control software.
By default hold is disabled. In this mode the red LED will no longer continue to ash after the logged reading 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 reading has returned to normal. 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.
