Hi E-Design, glad to see you are still on this forum.
A while ago I was describing ongoing problems I have had with my DMM6500. These have now worsened to the point where it is almost unuseable.
The continuous sampling just stops and starts completely at random with messages in the reading table, while in the non sampling mood, which mean nothing to me. The annoying thing is that sometimes the meter will run faultlessly for several days and then will suddenly start misbehaving. It is in a temperature stable workshop, in a permanent position in an equipment stack with good ventilation. HELP!! PLEASE it is driving me mad

I am attaching a screen shot, which clearly shows the periods when no sampling is occuring, I also have the csv file from the reading table which shows the messages in the table while it is not sampling, maybe they could give you a clue? Unfortunately this is too large to attach to this post.
Any help would be appreciated since this problem has plagued me since new, although it is now becoming so serious that the meter cannot be relied on.
Thank you and regards Mike
