Electrical and magnetic fields often are the cause for the
introduction of disturbing voltages into the measuring cir­
cuit.
Therefore:
S Use shielded low‐capacitance cable only (HBM cables
meet these requirements).
S Do not lay the measuring cables in parallel to power
cables, especially high‐tension and control lines. If
this is not possible, use steel conduits, for example, to
protect and shield the measuring cables.
S Avoid the stray fields resulting from transformers, mo­
tors and contactors.
