This product is a Class A (for industrial environment) product. Operation of this product in a
residential area may cause radio interference in which case the user will be required to correct the
interference.
Cable conditions
USB port (Function)
Use a shielded USB cable (3 m in length or less).
Measurement lead
Pass each measurement lead (L4059PR) three times through the supplied ferrite core to attach
it (see the figure below).
Attach the ferrite core as close as possible.
Immunity* Compliant standards
EN61326-1 Table 2 (for industrial environments)
However, the measured values may receive noise effects.
Cable conditions
Same as the emission cable conditions.
Environmental standard* Compliant standard

* Applies to products with CE marks. For information on products without CE marks, contact your nearest YOKOGAWA dealer.
1 The overvoltage category (installation category) is a value used to define the transient overvoltage condition and includes
the rated impulse withstand voltage. Overvoltage Category I applies to equipment that is connected to a circuit that has been
designed to suppress overvoltage caused by transient phenomena to an adequately low level.
2 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).
3 The measurement category of the CA700 signal terminals is Other (O). Do not use it to measure the main power supply or for
Measurement Categories II, III, and IV.
Measurement category O (Other) applies to measurement of circuits that are not directly connected to a main power source.
This category applies to measurement of secondary electric circuits in equipment across a transformer. The estimated transient
overvoltage that may appear at the CA700 signal input is 350 V.
Measurement category II applies to measurement of circuits, such as household electric appliances and portable electric tools,
that are connected to low-voltage installations.
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.
