Thats because the data was already there in the log, and each time you try it, the logger adds the same data
[size=50]a bit like an exponential groundhog day
Go check the log file, for the day(s) in question, and go through it carefully, you will see that the data has [/size]
repeated from a certain time namely 11-17 , when you 1st noticed the error and restarted the PC/WD
the logger would have gotten the data then, would it not? This is why more data has been added, happens
to me too, i just go in to the logfile and remove the double up data, save then go recreate the graphs
[/size]
[/size]You will see the erroneous data just delete it and save the logfile [size=small]
