Red flashing LED alarm: uncased Re-Ed loggers

These data loggers can be fitted with a red flashing LED.

Uncased Re-Ed data loggers are supplied with 2 LEDs, giving the option of fitting them to the PCB. If they are fitted to the unit, the red flashing LED is part of the logger's alarm feature. If it starts to flash, this means that environmental conditions have fallen outside the range that has been chosen during set up in the Tinytag Explorer software.

The red LED is not a warning of a low battery.
