NOTE:
It is recommended to erase the SD-card at the beginning of the measurements at a specific
location and to keep all the files on the SD-card throughout the whole monitoring period. In order to
have seamless (without any interruption) recordings (peak files if the vibration level was below the
trigger threshold or additionally event files if the vibration level exceeds the trigger threshold)
throughout the whole monitoring period, it is NOT possible to erase single files. The SD-card is
considered as documentary evidence.
