4 Functions of the pushbutton and states of the LED
The pushbutton at the front of the device must be pressed to turn the
meM-LOG-SE
on or off. Besides that, the
pushbutton features various functions, depending on how long it is pressed and in which state and operating mode the
logger is.
The two LEDs give useful information about the current device status. As soon as the power supply is connected and
the
meM-LOG-SE
is provided externally with power, the green LED is on. In this case, the integrated accumulator is
charged at the same time. The red LED indicates different states, being on or off or flashing in varying speed or dura-
tion.
The following table helps to get an overview of the various functions of the pushbutton depending on the current device
status, of possible settings and the resulting state of the red LED:
