Bob, We have been using the blue terminal block to attach a 4 wire load cell for years. Could we use the pins on the connecting block immediately next to the Terminal block, and get equivalent results. Am I correct in thinking that the blue terminal block location (+5VA, N1-, N1+, and GND) are equivalent to the PINs on the PIN block (EXC+, SG-, SG+, and EXCSNS-) .
