minimal impedance (< 1 ). Methods for grounding the transmitter case include:
Internal ground connection
The Internal Ground Connection screw is inside the terminal side of the electronics housing. The
screw is identified by a ground symbol ( ), and is standard on all 3051S MultiVariable
transmitters.
