RTD measurement with the BARD-700

With RTD input, the input source resistance is described in section 13.6, “General Specifications” of the user manual as: “10Ω or less per wire (the resistance of all three wires must be equal).” I'm using the BARD-700 safety barrier and the input resistance of the BARD is 130Ω, so can I perform measurement?

Yes, you can perform RTD measurements while using the BARD-700 safety barrier. When using the BARD, make it so that the resistance value excluding the BARD is 10Ω or less. Make the resistance the same on each of the 3 wires.
