11+ 3 Wire Rtd Wiring Diagram. Watlow series 980/985 user's manual. Approximate basic error error in reading is equivalent to unbalanced lead wire resistance(2) error in reading equivalent total lead wire 1.
Rtd excitation is provided from the module by two matched current sources. Simulate a 2 wire rtd sensor by setting the rw1 value to zero and by deleting the lower circuit branch containing rw4 and r4. Attach the sensor leads according to the wiring diagrams.
A wiring diagram is a streamlined standard photographic depiction of an electrical circuit.
