Operating Precautions
Shipping precautions
Hioki disclaims responsibility for any direct or indirect damages that may occur when this instrument
has been combined with other devices by a systems integrator prior to sale, or when it is resold.
Handling the Instrument
This instrument may cause interference if used in residential areas. Such use must be avoided un-
less the user takes special measures to reduce electromagnetic emissions to prevent interference
to the reception of radio and television broadcasts.
DANGER
To avoid electric shock, do not remove the instrument’s case. The internal com-
ponents of the instrument carry high voltages and may become very hot during
operation.
CAUTION
• Note that the instrument may be damaged if the applied voltage or current exceeds
the measurement range.
• Do not use excessive force on the touch panel, and do not use sharp objects that
could damage the touch screen.
• Do not apply heavy downward pressure with the stand extended. The stand could be
damaged.
• If the instrument exhibits abnormal operation or display during use, review the infor-
mation in “11.2 Troubleshooting” (p. 223) and “11.3 Error Massage and Error Dis-
play” (p. 230) 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.
• After use, always turn OFF the power.
Before Turning Power On
WARNING
•Before turning the instrument on, make sure the supply voltage matches that
indicated on its power connector. Connection to an improper supply voltage
may damage the instrument and present an electrical hazard.
•To avoid electrical accidents and to maintain the safety specications of this
instrument, connect the power cord provided only to a 3-contact (two-conductor
+ ground) outlet.
•Be sure to ground the power cord. Failure to do so will cause the enclosure to
have a voltage equal to half the supply voltage, resulting in electric shock.
• To avoid shock and short circuits, turn off all power before connecting probes or cords.
CAUTION
Do not connect the supply voltage improperly. Doing so may destroy the instrument’s
internal circuitry.
DC resistance measurement only
To suppress noise, the instrument needs to be set to match the frequency of the power source. Before
operating, set the instrument to the frequency of your commercial power. If the supply frequency is not set
properly, measurements will be unstable.
See “Line frequency (DC)” (p. 54).

Operating Precautions
Handling the cords, xtures, and probes
WARNING
If the insulation on a cord melts, the metal conductor may be exposed. Do not use
any cord whose metal conductor is exposed. Doing so could result in electric shock,
burns, or other hazard.
CAUTION
• To avoid breaking the cords or probes, do not bend or pull them.
• Avoid stepping on or pinching cords, which could damage the cord insulation.
• Keep in mind that, in some cases, conductors to be measured may be hot.
• To avoid damage to the instrument, do not short-circuit the measurement terminals
and do not input voltage to the measurement terminals.
• For safety reasons, disconnect the power cord when the instrument is not used.
• To avoid damaging the power cord, grasp the plug, not the cord, when unplugging it
from the power outlet.
• To prevent damage to the BNC connector or junction, be sure to release the locking
mechanism, grip the head of the connector (not the cord), and pull it out.
• Put the protective cap back on the connector when not in use. If the protective cap is
not properly inserted, dust or other foreign matter may enter the connector and cause
damage.
IMPORTANT
• Use only the specied connection cords. Using a non-specied cable may result in incorrect
measurements due to poor connection or other reasons.
Before using a xture or the like, read the instruction manual supplied with the product to
be used.
Before Using the USB Flash Drive
CAUTION
• Do not transport the instrument while a USB ash drive is connected. Damage could result.
• Inserting a USB ash drive upside down, backwards or in the wrong direction may
damage the USB ash drive and/or the instrument.
• Some USB ash drives are susceptible to static electricity. Exercise care when using such
products because static electricity could damage the USB ash drive or cause malfunc-
tion of the instrument.
IMPORTANT
• USB ash drives have a limited usable lifetime. After long-term use, data reading and writing
will fail, at which time the USB ash drives must be replaced.
• When a USB ash drive is accessed, the color of the USB icon changes from blue to red. Do
not turn off the power of the instrument while the USB ash drive is being accessed. Also,
never remove the USB ash drive from the instrument. Doing so may result in the data in the
USB ash drive being lost.
• Hioki cannot recover data from damaged or faulty storage media resulting from abnormalities. We
are also unable to provide compensation for such data loss,regardless of the contents or cause
of the failure or damage. We recommend making a backup of all important data on a computer or
other storage devices..
