I'm considering DAC1500 or 1046 Bridge for measuring temperatures with RTDs. I'm a little confused with the guides. https://www.phidgets.com/docs/1046_User_Guide#Bridge_Input 1) I assume what is referred as bridge voltage (Vb) is the voltage that is on the 5V terminal. And this terminal is an output...

Thanks for the fast reply Patrick There are a few things that make me think it is not the IC sensor. 1) I see this on all three probes I have connected and the "step" happens at different times depending upon the probe. 2) This happens after very long periods of being on and running (very ...

I noticed recently that all 4 channels of my Phidget 1048 has poor 0.2deg C resolution. When temps fall slowly, I can see this with Phidgets Control Panel. Basically temps hold than then step downward 0.2C. Weird thing is, the temp does change slightly as it samples. I just updated the control panel...
