Why does my roast curve flatline

We have seen a few of these roast curves where the temperature cuts out while roasting and then goes back to reading as though nothing happened. This results in a strange peak and valley in the RoR (Rate of Rise.) 

This can happen for a few reasons.

• Your computer has gone to sleep during a roast (most common)
• Your databridge is too hot
• Your USB is removed from the roaster
• Your computer is overheating

If your computer is going to sleep during a roast you can change the display time out time to something longer than your roast time.
