Can I connect 4 wire PT100 to CR1000 directly?

fmr2007 Oct 15, 2020 04:09 PM

I had used shortcut program to connect 4 wire PT100 sensors

But I couldn't find this sensor in the menu.

We connect them using 10k ohm resistance and then calculate the result of voltset instruction 

Can we connect 4 wire PT100 to CR1000 without resistance

Thank you for your help

A fixed value reference resistor must be used, and the CR1000 does not have such a reference internally. An external resistor must be used like you have done in the past.
