Notes on Use
────────────────────────────────────────────────────
WARNIN
Before turning on the power, make sure that the voltage of the power
supply being used matches the supply voltage indicated on the rear
panel of the unit.
Before turning the product on, make sure the source voltage matches
that indicated on the product’s power connector. Connection to an
improper supply voltage may damage the product and present an
electrical hazard.
WARNIN
To avoid electrical accidents, remove power from the circuit before
connecting the voltage cord.
CAUTIO
To avoid electric shock and short-circuit accidents, use only the supplied test
leads to connect the product input terminals to the circuit to be tested.
DANGE
Connect the clamp-on sensors or voltage cords to the product first, and
then to the active lines to be measured. Observe the following to avoid
electric shock and short circuits.
・Do not allow the voltage cable clips to touch two wires at the same
time. Never touch the edge of the metal clips.
・When the clamp sensor is opened, do not allow the metal part of the
clamp to touch any exposed metal, or to short between two lines, and
do not use over bare conductors.
Clamp sensor should only be connected to the secondary side of a
breaker, so the breaker can prevent an accident if a short circuit occurs.
Connections should never be made to the primary side of a breaker,
because unrestricted current flow could cause a serious accident if a
short circuit occurs.
