Re: temperature jumps


Every now and then a section of the curve is displaced upwards. For a period
of about 5 minutes the temperatures recorded are about 4 degrees higher,
then they drop back down to be once again consistent with earlier
measurements. Obviously a measurement problem. Does anyone know what
causes it?


I've seen behavior like that as well, and it was always due to an equipment
problem. Do all of your rigs do this, or just one? It sure sounds like a bad
connection somewhere. Another possibility is interference on the serial line.
