EASYLOG SOFTWARE GUIDE
Conguring Alarm Levels
LEDs on some data loggers indicate whether an alarm has been activated. Consult the relevant data logger
datasheet for details of the availability of this feature and the LED flashing modes.
An LED will flash red when the logged reading has exceeded a Low or High alarm level. By default Hold is
disabled. In this mode the red LED will no longer continue to flash after the logged reading has returned to
normal from an alarm condition.
Hold can be turned on via the EasyLog USB software. In this mode, the red LED that indicates an alarm
condition will continue to flash, even after the logged reading has returned to normal. The red LED will
effectively have latched into its alarm condition. This feature ensures that you are notified that an alarm
level has been exceeded, without the need to download the data from the logger.
