Hello, new here. Wondering what could be the cause of error in subject?
 It's a K2000r with sampling option. It also blew fuses for a while. I changed fuses and changed to 240V (was 220V) as we have 230V here in Sweden. It didn't blow any fuses yet after that.
 It seems to work ok, but I am worried about the error in the test. 
 Suggestions? I got a tip about Roger J here could answer.
 

 Kind regards
 

 Michael
