3.6 Grounding the transmitter
The Rosemount 705 Transmitter operates best with the housing grounded. Floating systems, however,
can cause extra noise that may affect the accuracy of the transmitter. If the signal appears noisy or
erratic, grounding at a single point may solve the problem. Grounding of the electronics enclosure
should be done in accordance with local and national installation codes. Grounding is accomplished
through the process connection using the internal or external case grounding terminal.
