It is recommended to follow this procedure : The record process is:
Seek PEC Index
Start guiding
Start PEC recording
Wait until it has completed.
Further PEC records can be done, collecting multiple PEC record cycles and averaging them can produce a better PEC record.
Thus I recorded 3 consecutive PEC files to be averaged.
However these files are so much different that their average would be meaningless.
I attach the content of these 3 files
Has someone got some experience in averaging these .csv files ?
