5.1 LEDs/Buttons
There is one red-green-orange LED (light emitting diode) and two buttons:
control and eject. The LED indicates the status of the module. The LED will
flash red when the CF card is being accessed, solid green when it is OK to
remove the card, solid orange to indicate an error, and flashing orange if the
card has been removed and has been out long enough that CPU memory has
wrapped and data is being overwritten without being stored to the card. The
control button must be pressed before removing a card to allow the datalogger
to store any buffered data to the card and then power it off.
The CFM100 will consume more current if a Status LED is
continuously on. When a red or green LED is continuously on,
add 1 mA to the power consumption. When an orange LED is
continuously on, add 2 mA to the power consumption. NOTE
5.2 Power
5.2.1 Primary Power
