Small picture, a bit hard to interprent. The green is?

I think I correctly interprented the length of the plot to a week (the 
lower plot shows a regular pattern of 7 cycles and I think I interprent 
the red text to day 168,71 hrs). If it would have been a frequency jump 
it would track in faster than half a day. Can you come to think of 
something else that could have happend to the equipment that day?

Cheers,
Magnus
