Usage Notes
Shipping precautions
Hioki disclaims respo nsibili ty for any di rect or indi rect da mages that ma y occ ur when this instrume nt has
been combined with other devices by a systems integrator prior to sale, or when it is resold.
Handling the Instrument
To avoid electric shock, do not remo ve the ins trument's case. The interna l components of the instrument carry high voltages and may become very hot during
operation.
• If the instrument ex hib its ab nor ma l o per ation or dis pl ay du ri ng use , rev ie w the inf or mation in Trouble shooting section "11.2 Trouble Shooting" (p. 175) and E rror Indications section "11.3 Error Indication" (p. 177) before contacting your dealer or
Hioki representative.
• 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 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 d isconnect all cables, remo ve any CF card and USB
memory, and carry it by the handle.
• Do not apply hea vy downward pressure wit h the stand extended. The stand c ould
be damaged.
See "Using the Handle as a Stand" (p. 13)
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 measu red. Observe the following to avoid electric sho ck
and short circuits.
• Do not allow the voltage cord clips to touch two wires at t he 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.
• T o avoid short ci rcuits and potentially life-threatening haz ards, never att ach the
current sensor to a circu it that operates at more than the ma ximum 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 ac cident if a short
circuit occurs. Connections should never be made to the primary side of a
breaker, because unrestricted current flow could cause a serio us accident if a
short circuit occurs.
• Connect only those voltage cables necessary for measurement.
7
Usage Notes
In order to use the 9709 AC/DC Current Sens or, 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 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 prevent an electric shock accident, con firm that the white or red portion (insulation layer) inside the cab le is not exp osed. I f a colo r insid e the ca ble is expo sed, do
not use the cable.
• To avo id 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 avo id 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 con nec to r, be sure to release t he l oc k befo re pul li ng off the
connector. Forcibly pulling the connector without releasing the lock, or pulling on the
cable, can damage the connector.
• To prev ent dam age to th e in st ru men t and cu rre nt s ens ors , nev er c on nec t or di s co nnect a sensor while the power is on, or wh ile the sensor i s clamped aroun d a conductor.

Usage Notes
Before Connecting Measurement Cables
• The maximum input voltage is 1500 VDC, 1500 Vrms. Attempting to measure
voltage in excess of the maximum input could destroy the instrument and
result in personal injury or death.
• Never exceed a current sensor’s input current rating. Doing so could destroy
the instrument and cause personal injury.
• The maximum rated voltage between input terminals and the ground is as follows;
(CAT II) 1000 VDC, 1000 Vrms
(CAT III) 600 VDC, 600 Vrms
Attempting to measure voltages exceeding this level with respect to ground
could damage the instrument and result in personal injury.
• Before turning the inst rument 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 speci fications of this
instrument, connect the power cord only to a 3-contact (two-conductor +
ground) outlet.
The power supply voltage for this product is switchable. To avoid electrical accidents, check that the voltage selector is set correctly for the supply voltage you
are using.
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 termina ls, or curren t sensors. Do ing so may damag e the instru ment.
• Note that the instrument ma y be damaged if the ap plied voltage or curr ent 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 dealer or Hioki representative as soon as possible. Continuing to use the instrument may result in fire or electric shock.
