It is advised to use this power supply when the M3 is panel mounted.

on the footswitch, one line will be added on the CSV file. (a « output.csv » file is

If the USB stick is not connected when the operator transfers the measurement, an
error message will pop up.
USB sticks with partitions are not supported.
