Instructions for EMC
651K9
When subjected to an RF Interference, the
651K9 will maintain the +1% accuracy in
all frequency ranges. In order to achieve
the stated accuracy for the 651K9, a
shielded cable, cable gland, shield bead
and the probe should be mounted in a
metallic vessel. SOR recommends using
a shielded cable made of PVC
Insulation around a tinned copper braid
shield (Olflex CY cable or equivalent).
Refer to illustrations for installation of
shield bead onto the probe wire.
