I'm using a DAQ NI-6220 with a SC-2042-RTD, when I run the test panel in Measurement and Automation Explorer I get strange behavior from all the 8 diffrent input channels. First time I used the setup I had ni problem at all, then I adjusted the potentiometer for the current excitation and then something strange happend. I have calibrated the excitation so that it is 1mA, but it stills seems to be something wrong. When I run the testpanel the voltage for all the channels drops at a "low speed" to almost 2V. What could the problem be ?
