readout problems using FP TC-120

[PeBa]

Hi all,

I have problems with TC-120. There are 7 thermocouples connected, 3 type S and 4 of type K. After running some time (1-2 hours) the readout of one ore more channels becomes swinging from min to max. I do not see any stray current problems. The problem does not occur permanently. Any idea is appreciated. rg
