Reducing interference signal injection

► keep the measuring leads as short as possible
► connect the MX809B housing to ground potential by
using the grounding screw on the back
► use pairs of shielded cables (ensure approval), con­
nect the shield to ground potential
► route unshielded measuring leads close together,
channel by channel; avoid large loop areas
► twist the unshielded measuring leads together
► physically separate leads for measuring sensitive,
small signals from measuring leads connected to
sources that are subject to interference or highly
dynamic
► do not route measuring leads next to potentially inter­
fering devices such as motors, inverters, etc.
