3.4 Grounding the Duct
CAUTION
When such equipment as an electrostatic dust collector is used, be sure to ground both the duct
and the DT450G. Otherwise, there may be a danger of electrical shock due to high potential
static electricity.
If a duct or other alternative facility where the DT450G is mounted is charged with electricity, the
electricity will serve as noise, possibly affecting the signal under measurement. Ground the duct
where the DT450G is mounted, as well as other nearby structures, in order to prevent the duct
from being charged with electricity.
