Thanks Fausto I can certainly try some of these, however acquisition rate makes no difference, the step-jumps happen at 10Hz, 60Hz or multi-kHz. What is more confusing to me though is that if I look at the voltages directly, the steps are either not present, or are just much smaller than the noise and the conversion from volts to degrees is then quantized to the point that it is jumping between two conversion levels.. The following screen shot its 2 identical TCs placed adjacent to each other, one in voltage mode and the other in temperature mode. Thanks S

Hi When reading in 2 channels of the USB2048 (both with k-type TCs attached). If I set the channels up in temperature mode, the readings have these discrete jumps in them. In voltage mode, the readings are just continually varying as the process temperatures oscillate. 1.png is long term temp mode showing disctete jumps, 2.png shows the jumps more clearly over a short time span. 3.png shows the channels set up in voltage mode, showing no discrete jumps. Any idea on where the discrete jumps are coming from in temperature mode? Thanks
