(4) Grounding
WARNING
For the wiring of protective grounding, terminate the
cable finish with round shaped crimp terminal with
insulation cover (for M4 screw), and connect it to the
proctective grounding terminal reliably.
CAUTION
The grounding should satisfy Class D requirements
(grounding resistance, 100 Ω or less).
IMPORTANT
Improper grounding may result in an adverse effect on
the flow measurement. Ensure that the instrument is
properly grounded.
