Ground the transmitter
The transmitter will operate with the housing either floating or grounded. However, the
extra noise in floating systems affects many types of readout devices. If the signal appears
noisy or erratic, grounding the transmitter at a single point may solve the problem.
The electronics enclosure should be grounded in accordance with local and national
installation codes. This can be accomplished via the process connection, via the internal
case grounding terminal, or via the external grounding terminal.
Thermocouple, mV, and RTD/Ohm inputs
Each process installation has different requirements for grounding. Use the grounding
options recommended by the facility for the specific sensor type, or begin with grounding
Option 1 (the most common).
