Notes on Use
Follow these precautions to ensure safe operation and to obtain the
full benefits of the various functions.
Preliminary Checks
DANGER
To avoid short circuits and potentially life-threatening
hazards, never attach the device to a circuit that operates
at more than 600 Vrms, or over bare conductors.
Connect the device to the instrument first, and then to the
active lines to be measured.
Observe the following to avoid electric shock and short
circuits.
When the clamp jaws are opened, do not allow the metal
part of the jaws to touch any exposed metal, or to short
between two lines, and do not use over bare conductors.
This device should only be connected to the secondary
side of a breaker, so the breaker can prevent an accident if
a short circuit occurs. Connections should never be made
to the primary side of a breaker, because unrestricted
current flow could cause a serious accident if a short
circuit occurs.
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
Check the position of the range switch before taking
measurements. Note that the device may be damaged if
current exceeding the selected measurement range is applied
for a long time.
To prevent damage to the connected instruments, never
connect or disconnect a sensor while the power is on, or while
the sensor is clamped around a conductor.
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.
To avoid damage to the device, protect it from physical shock
when transporting and handling. Be especially careful to avoid
physical shock from dropping.
Keep the clamp jaws and core slits free from foreign objects,
which could interfere with clamping action.
NOTE
Correct measurement may be impossible in the presence of
strong magnetic fields, such as near transformers and highÂcurrent conductors, or in the presence of strong electromagnetic
fields such as near radio transmitters.

Measurement Procedure (AC A)
CAUTION
When disconnecting the BNC connector, be sure to release the
lock before pulling off the connector. Forcibly pulling the
connector without releasing the lock, or pulling on the cable, can
damage the connector.
When input to our recorder or tester, use 0.2 VAC range.
1. Connect the output terminals to the input terminal. When using
the BNC connector, align the BNC connector with the connector
guide notch on the current input connector. While pushing the
connector in, turn it to the right to lock it.
2. When input the unknown amount of measuring current, set the
range to the largest one (1000 A).
3. Open the jaws and clamp the conductor.
4. Confirm whether the jaws tip connection part is closed certainly.
5. Set the proper range of the clamp on probe according to the
measurement value.
Do not set the range from the measurement equipment (the
recorder etc.)
NOTE
Attach the clamp around only one conductor. Single-phase (2-wire)
or three-phase (3-wire) cables clamped together will not produce any
reading.

Maintenance and Service
Cleaning the device
To clean the device, wipe it gently with a soft cloth moistened with
water or mild detergent. Never use solvents such as benzene,
alcohol, acetone, ether, ketones, thinners or gasoline, as they can
deform and discolor the case.
Service
If the device seems to be malfunctioning, confirm that the probes is
not open circuited before contacting your dealer or Hioki
representative. Pack the device so that it will not sustain damage
during shipping, and include a description of existing damage. We
cannot accept responsibility for damage incurred during shipping.
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 or Hioki
representative.
Before using the device, make sure that the insulation on the
probes is undamaged and that no bare conductors are improperly
exposed. Using the device in such conditions could cause an
electric shock, so contact your dealer or Hioki representative for
repair.
