NI-9212 for Grounded Thermocouple Measurements

Hardware

  • SCXI-1303
  • NI-9212

Issue Details

I have seen warnings regarding taking grounded temperature readings and damaging the resistors network. My C Series compactDAQ module (such as the NI-9212) has non-removable, internal resistors; should I be worried about damaging the hardware?

Solution

No, you will not damage the hardware. This is only a concern when you have low resistance values, as this may induce a high current across the resistor. As long as you are grounding your system appropriately, you can rely on safe, accurate measurements from your C Series module.
