    The latest test came to a runtime of about 2,5 days.

    On the SD Card i Found ~20.000 Measurements.

    I only expected something like 7200 Measurements.

    Somehow the cycletime of the MSP430 increased by 100%...

    Here is the Datasnipped:

12.09.2019 21:02:50	217	6,3	28	47	118	117	118	11

    So i found two Problems:

    - The intervalltime was to short

    - The ADC was not working properly.. (It should have recorded the Voltage of the batteries, but the value stays almost the same the whole time)

    Hints, Thoughts and Comments are recommended.

    Testing went really bad until now..

    1. Test: The (really cheap) batteries leaked and 2 Batteries had 0V. The Setup recorded for ~8h
    2. Test: The ground cable detached itself from the battery ground ... (it's always a ground problem)
    3. Test: With newly soldered cable and new (more expensive) batteries... still testing in progress.
