1 Applies to products with CE marks. For information on other products, contact your nearest YOKOGAWA dealer.
2 The overvoltage category (installation category) is a value used to define the transient overvoltage condition and includes the
rated impulse withstand voltage. CAT II applies to electrical equipment that is powered through a fixed installation, such as a
wall outlet wired to a distribution board.
3 This instrument is measurement category II product. Do not use for Measurement Categories III and IV.
Measurement category O applies to measurement of other circuits that are not directly connected to a main power source.
Measurement Category II applies to electrical equipment that is powered through a fixed installation, such as a wall outlet
wired to a distribution board, and to measurement performed on such wiring.
Measurement category III applies to measurement of facility circuits, such as distribution boards and circuit breakers.
Measurement category IV applies to measurement of power source circuits, such as entrance cables to buildings and cable
systems, for low-voltage installations.
4 Pollution Degree applies to the degree of adhesion of a solid, liquid, or gas that deteriorates withstand voltage or surface
resistivity.
Pollution Degree 2 applies to normal indoor atmospheres (with only non-conductive pollution).
5 Use cables of length 3 m or less.
6 Use cables of length 30m or less.
