Influence of Noise
It is efficient to take measures for conductive noise by monitoring with the HIOKI 3145 Noise
HiLogger. When the entry route is identified, taking the measures as shown in the figure below
is effective.

Separating the power line
It is desirable to prepare a different power line for the power system, welder, etc.
Inserting a common mode filter (EMI choke) in the entry route
Selecting and inserting several common mode filters with a high impedance level increases
effectiveness.
