Hi everyone! I have a an SA1-RTD from Omega.com I found lying around and wanted to try and use it. It's the 3 wire version with 1 red lead and 2 black leads. I was wondering if someone could help me figure out how to test if this still works. I've tried using a multimeter across the red and both black leads, but i get nothing. I have continuity between both the black leads though. I'm stumped lol.
Oh, the link to mfg is here:http://www.omega.com/ppt/pptsc.asp?ref=sa1-rtd
An RTD is just a resistor that changes with temperature at a known rate. If you don't read a resistance between the red and either black wire then the platinum element is open and thus useless.
