4.3.1 Shielding and grounding
In environments subject to electrical interference, shielded and twisted wires enable precise
measurement results.
The electrical wiring of the data bus must be installed properly and shielded in order to enable
precise measurement results.
IMPORTANT NOTE! IMPORTANT NOTE! IMPORTANT NOTE! IMPORTANT NOTE!
If you use non-shielded wires, they must not be laid near power cables or electrical loads.
In order to ensure the electromagnetic compatibility of the entire measuring system, all
components must be shielded and grounded.
The shields and grounds must provide complete protection against interference.
