RANGE
key.
Display 2 and Display 3 then restore the measured
values.
Accurate measurement may be impossible in
locations subject to strong external magnetic fields,
such as transformers and high-current conductors, or
in locations subject to strong external electric fields,
such as radio transmission equipment.
Make sure that only one conductor is clamped in
the center of the clamp sensor. If you clamp single-
phase (2-wire) or three-phase (3-wire) lines together,
it will be impossible to measure.
