key.
2. Clamp the tester on the conductor, so that
the conductor passes through the center of
the clamp core. For measurement of grounded
leads, clamp the tester on one lead only (see
a). For overall measurements, clamp the
tester on the entire circuit path (see B).
･ When the current to be measured is
unknown, begin measurement with the 200 A
range selected (filter off).
