Installing
• The instrument should be operated only with the bottom or rear side downwards.
• Vents (on the right side of the instrument) must not be obstructed.
8
Usage Notes
Handling the instrument
To avoid electric shock, do not remove the instrument's case. The internal components of the instrument carry high voltages and may become very hot during
operation.
• If the instrument exhibits abnormal operation or display during use, review the information in Troubleshooting section "11.2 Trouble Shooting" (p. 219) and Error Indications section "11.3 Error Indication" (p. 222) before contacting your authorized
Hioki distributor or reseller.
• To avoid damage to the instrument, protect it from physical shock when transporting
and handling. Be especially careful to avoid physical shock from dropping.
• To move the instrument, first disconnect all cables, remove any CF card and USB
memory, and carry it by the handle.
• Do not apply heavy downward pressure with the stand extended. The stand could
be damaged.
See "Using the Handle as a Stand" (p. 15)
• Use a common ground for both the instrument and any devices to be connected.
Using different ground circuits will result in a potential difference between the instrument's ground and the computer's ground. If the communications cable is connected
while such a potential difference exists, it may result in equipment malfunction or
failure.
• Before connecting or disconnecting the communications cable, always turn off the
instrument and any devices to be connected. Failure to do so could result in equipment malfunction or damage.
• After connecting the communications cable, tighten the screws on the connector
securely. Failure to secure the connector could result in equipment malfunction or
damage.
This instrument may cause interference if used in residential areas. Such use must be
avoided unless the user takes special measures to reduce electromagnetic emissions
to prevent interference to the reception of radio and television broadcasts.
Handling the cords and current sensors
Connect the current sensors or voltage cords to the instrument first, and then to
the active lines to be measured. Observe the following to avoid electric shock
and short circuits.
• Do not allow the voltage cord clips to touch two wires at the same time. Never
touch the edge of the metal clips.
• When the current sensor is opened, do not allow the metal part of the clamp to
touch any exposed metal, or to short between two lines, and do not use over
bare conductors.
• To avoid short circuits and potentially life-threatening hazards, never attach the
current sensor to a circuit that operates at more than the maximum rated voltage to earth (See your current sensor's instruction manual for its maximum ratings.)
• Current sensor and voltage cables 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.
• Connect only those voltage cables necessary for measurement.
• To prevent an electric shock accident, confirm that the white or red portion
(insulation layer) inside the cable is not exposed. If a color inside the cable is
exposed, do not use the cable.
9
Usage Notes
• In order to use the CT6862 AC/DC Current Sensor, the line to be measured
must be temporarily disconnected.
To avoid shock and short circuits, turn off the power to lines to be measured
before making connections to terminals to be measured and turning on the
instrument.
• To avoid electric shock, do not exceed the lower of the ratings shown on the
instrument and test leads.
• To avoid electric shock and short-circuit accidents, use only the specified voltage
cord to connect the instrument input terminals to the circuit to be tested.
• For safety reasons, when taking measurements, only use the optional voltage cord.
Avoid stepping on or pinching cables, which could damage the cable insulation.
• To avoid breaking the cables, do not bend or pull them.
• To avoid damaging the power cord, grasp the plug, not the cord, when unplugging it
from the power outlet.
• Keep the cables well away from heat sources, as bare conductors could be exposed
if the insulation melts.
• Be careful to avoid dropping the current sensors or otherwise subjecting them to
mechanical shock, which could damage the mating surfaces of the core and
adversely affect measurement.
• Be careful when handling the cords, since the conductor being measured may
become very hot.
• When disconnecting the 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.
• To prevent damage to the instrument and current sensors, never connect or disconnect a sensor while the power is on, or while the sensor is clamped around a conductor.
10
Usage Notes
Before connecting measurement cables
• Do not use the instrument with circuits that exceed its ratings or specifications. Doing so may damage the instrument or cause it to become hot, resulting in bodily injury.
• Never exceed a current sensor’s input current rating. Doing so could destroy
the instrument and cause personal injury.
• Before turning the instrument on, make sure the source voltage matches that
indicated on the instrument's power connector. Connection to an improper
supply voltage may damage the product and present an electrical hazard.
• To avoid electrical accidents and to maintain the safety specifications of this
instrument, connect the power cord provided only to an outlet.
For safety reasons, disconnect the power cord when the instrument is not used.
Before connecting to the lines to be measured
To avoid electrical hazards and damage to the instrument, do not apply voltage
exceeding the rated maximum to the external input terminals.
• To avoid electrical accidents, confirm that all connections are secure. The
increased resistance of loose connections can lead to overheating and fire.
• Ensure that the input does not exceed the maximum input voltage or current to
avoid instrument damage, short-circuiting and electric shock resulting from
heat building.
• When the power is turned off, do not apply voltage or current to the voltage input terminals, current input terminals, or current sensors. Doing so may damage the instrument.
• Note that the instrument may be damaged if the applied voltage or current exceeds
the measurement range.
While measuring
If an abnormality such as smoke, strange sound or offensive smell occurs, stop
measuring immediately, disconnect from the measurement lines, turn off the
instrument, unplug the power cord from the outlet, and undo any changes to the
wiring. Contact your authorized Hioki distributor or reseller as soon as possible.
Continuing to use the instrument may result in fire or electric shock.
