WARNING
• Make sure to avoid an electric shock when connecting the probe to the object of
measurement. Do not remove the probe from the measuring instrument after the object
of measurement is connected.
• When disconnecting the probe BNC output connector, first turn OFF the power to the
circuit under measurement. Then, disconnect the probe from the high voltage parts of the
circuit under measurement.
CAUTION
Use a soft cloth to clean the dirt. Prevent damage to the probe. Avoid immersing the probe,
using abrasive cleaners, and using chemicals contains benzene or similar solvents.

categories, the lower measurement category applies. See below for definitions of measurement categories.
Measurement Category Definition
Measurement category “O
(Other)”
Measurement category O (Other) applies to measurement of a
circuit that is not connected directly to the main power source.
Measurement category II
(CAT II)
CAT II applies to measurement of electrical equipment that is
powered through a fixed installation such as a wall outlet wired to
a distribution board and measurement on such wiring.
Measurement category III
(CAT III)
CAT III applies to measurement at the distribution level, that is,
building wiring, fixed installations.
Measurement category IV
(CAT IV)
CAT IV applies to measurement at the primary supply level, that
is, overhead lines, cable systems.
4 Pollution degree applies to the degree of adhesion of a solid, liquid, or gas which deteriorates withstand
