SAFETY INSTRUCTIONS
Safety Symbols
This manual contains information and warnings essential for safe
operation of the device and for maintaining it in safe operating
condition. Before using the device, be sure to carefully read the
following safety notes.
The symbol printed on the device indicates that
the user should refer to a corresponding topic in the
manual (marked with the symbol) before using
the relevant function.
In the manual, the symbol indicates particularly
important information that the user should read
before using the device.
Indicates that application around or removal from
live lines is only permitted on condition that the
lines are insulated.
Indicates a grounding terminal
Indicates AC (Alternating Current)
Indicates the ON side of the power switch.
Indicates the OFF side of the power switch.
Indicates a fuse.

The following symbols in this manual indicate the relative
importance of cautions and warnings.
DANGER Indicates that incorrect operation presents an
extreme hazard that could result in serious injury or
death to the user.
WARNING Indicates that incorrect operation presents a
significant hazard that could result in serious injury
or death to the user.
CAUTION Indicates that incorrect operation presents a
possibility of injury to the user or damage to the
device.
NOTE Indicates advisory items related to performance or
correct operation of the device.
(Measurement categories) EN 61010-1:2001 specifies the
measurement categories and their requirements as follows. The
device falls under category I.
•Measurement category IV is for measurement performed at the
source of a low-voltage installation.
•Measurement category III is for measurement performed in a
building installation.
•Measurement category II is for measurement performed on
circuits directly connected to a low voltage installation.
•Measurement category I is for measurements performed on
circuits not directly connected to Mains.
PRECAUTIONS

PRECAUTIONS
Follow these precautions to ensure safe operation
and to obtain the full benefits of the various
functions.
Preliminary Check
Before using the device the first time, verify that it operates normally
to ensure that the no damage occurred during storage or shipping. If
you find any damage, contact your dealer.
DANGER
•To avoid short circuits and potentially life-
threatening hazards, never attach the GCP-530 or
GCP-1030 to a circuit that operates at more than
300V, or over bare conductors.
•When conductors being measured carry in excess
of the safe voltage level (SELV-E) and not more
than 300 V, to prevent short circuits and electric
shock while the core section is open, make sure
that conductors to be measured are insulated with
material conforming to
(1) Measurement CategoryⅠ,
(2) Basic Insulation Requirements for Working
Voltages of 300 V, and
(3) Pollution Degree 2.
For safeties sake, never use this sensor on bare
conductors. The core and shield case are not
insulated.

Un-insulated
(core and
shield case)
•Be careful to avoid damaging the insulation
surface while taking measurements.
•This instrument is made for use with the GCP-
206P or GCP-425P POWER SUPPLY. It is possible
to use a power supply other than the GCP-206P or
GCP-425P, provided that the connector and pin
assignments match, and that voltage and other
electrical specifications are satisfied. In the interest
of safety, make sure that the power supply has a
protective earthing with double- insulation
construction.
•Make sure that the waveform measuring
equipment connected to this device's output
terminal (BNC) is equipped with a protective
earthing with double-insulation construction.
•If the waveform measuring instrument being
connected to the output terminal (BNC) on this
device is equipped with any other measurement
terminals, take the following precautions to ensure
that the other instrument does not form a bridge
between the probe and any hazardous live of a
part.
1. Isolate the terminal to which the probe is
connected from other terminals on the measuring
instrument using basic insulation conforming to
the measurement category, working voltage, and
pollution degree requirements of the circuit being
tested.
PRECAUTIONS
9
2. If basic insulation requirements cannot be met
between the terminal to which this device is
connected and other terminals of the measuring
instrument, make sure that the voltage input to
the measurement terminal does not exceed the
safe voltage level (SELV- E).
3. Read and observe all warnings and precautions
relating to electrical safety for the measuring
instrument being connected to the probe.
Refer to the following standards regarding the
meanings of underlined terms.
IEC61010-1
IEC61010-031
IEC61010-2-032
•Be sure to observe all operating precautions for the
waveform monitoring instrument (oscilloscope or
recorder) and other measurement instruments to
which this device is connected.
•When using a measurement instrument that does
not provide isolation between its input terminals
and chassis or other input terminals, please pay
attention to the following points. If a signal is
applied to an input terminal other than that to
which this device is connected, do not connect the
ground-side terminal to any non-ground potential.
Otherwise, short-circuit current will flow through
the GCP-206P or GCP-425P or this device from the
ground terminal, which could cause an electrical
accident or damage.

WARNING
•Do not allow the device to get wet, and do not take
measurements with wet hands. This may cause an
electric shock.
•To avoid electric shock when measuring live lines,
wear appropriate protective gear, such as insulated
rubber gloves, boots and a safety helmet.
CAUTION
•To avoid damage to the device, protect it from
physical shock when transporting and handling.
Be especially careful to avoid physical shock from
dropping.
•This device should be installed and operated
indoors only, between 0 and 40°C (32 to 104°F) and
80% RH or less.
•Do not store or use the device where it could be
exposed to direct sunlight, high temperature or
humidity, or condensation. Under such conditions,
the device may be damaged and insulation may
deteriorate so that it no longer meets
specifications.
•This device is not designed to be entirely
waterproof or dustproof. To avoid damage, do not
use it in a wet or dusty environment.
