needs to have one point grounding.
• In case of R.T.D input, please connect 3 wires without resistance difference
among three wires.
• Please connect Input, Output signal wire separately from power line.
• In case of current input, please attach resistance 250 Ω 0.1 % at the end
of input terminals and use it accordingly.
