Make sure that the voltage input level does not
exceed DC1000V/AC750V.
Make sure the current input level does not
exceed 12A.
Do not place any heavy object on the
instrument.
Avoid severe impact or rough handling that can
lead to damaging the instrument.
Do not discharge static electricity to the
instrument.
Use only mating connectors, not bare wires, for

Do not disassemble the instrument unless you
are qualified as service personnel.
Make sure that the COM terminal to earth is
limited to 500Vpk.
Remove all test leads before disconnecting the
mains power cord from the socket.

their requirements as follows. The GDM-8351 falls under category II
600V.
Measurement category IV is for measurement performed at the
source of low-voltage installation.
Measurement category III is for measurement performed in the
