Note 2
⋅ Resonance may be
frequency of the current being measured. This will not
affect measurement.
⋅ In some cases, the position of the insulating target
conductor to be measured in the clamp window may affect
measurement. Make sure the insulating target conductor
to be measured is in the center of the clamp window.
⋅ When measuring signals containing high frequency
components, the measurements may be affected if the
side of the cable with high potential is clamped. Always
clamp the low potential side.
Generator
⋅ Accurate measurements may not be obtained near
transformers, cables carrying strong current and other
objects that generate a strong magnetic field, or near radio
transmitters or other equipment that generates a strong
electrical field.
