LED Flashing Modes

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 control 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.
