Measurement Procedure
Before using the instrument, be sure to read “Verifying before
usage” (p. 9).
DANGER
• Connect the instrument only to the secondary side
of a breaker. The breaker can prevent an accident
if a short circuit occurs. Do not connect the
instrument to the primary side of a breaker. Doing
so can cause a short circuit, which allows large
current to ow, causing a serious accident.
• Connect the test lead to the instrument rst, and
then to the active lines to be measured. To avoid
an electric shock and short circuits, do not short-
circuit two wires to be measured by bringing the
metal part of the test lead’s clip into contact with
them. Never touch the metal end of the clip.
