Grounding
Ground the turbine meter electronics internally for safe operation. Connect a wire to the
chassis ground lug located inside the LME as the primary ground. A secondary ground is
located outside of the LME. Refer to
and
never be connected to chassis ground.
Prepare the turbine meter for use
