Safety Notes

Safety Notes

This instrument is designed to conform to IEC 61010 Safety
Standards, and has been thoroughly tested for safety prior to
shipment. However, using the instrument in a way not described in
this manual may negate the provided safety features.

Before using the instrument, be certain to carefully read the
following safety notes.

DANGER

Mishandling during use could result in injury or death,
as well as damage to the instrument. Be certain that
you understand the instructions and precautions in
the manual before use.

WARNING

With regard to the electricity supply, there are risks
of electric shock, heat generation, fi re, and arc
discharge due to short circuits. If persons unfamiliar
with electricity measuring instruments are to use
the instrument, another person familiar with such
instruments must supervise operations.

Protective gear

WARNING

Safety Notes

Measurement categories

To ensure safe operation of measuring instruments, IEC 61010
establishes safety standards for various electrical environments,
categorized as CAT II to CAT IV, and called measurement categories.

DANGER

Usage Notes

Usage Notes

Follow these precautions to ensure safe operation and to obtain the
full benefi ts of the various functions.

DANGER

If the test lead or the instrument is damaged, there is
a risk of electric shock. Before using the instrument,
perform the following inspection.

• Before using the instrument, check that the coating of

the test leads are neither ripped nor torn and that no
metal parts are exposed. Using the instrument under
such conditions cou l d resu lt i n e lectrocuti on. Replace
the test leads with those specifi ed by our company.

• To avoid electric shock, check that the white or

red portion (insulated layer) within the cable is not
exposed. Do not use the cable if its internal colored
portion is exposed.

• Before using the instrument the fi rst time, veri fy that i t

operates normally to ensure that no damage occurred
during storage or shipping. If you fi nd any damage,
contact your authorized Hioki distributor or reseller.

Usage Notes

Installation

Installing the instrument in inappropriate locations may cause a
malfunction of instrument or may give rise to an accident. Avoid the
following locations.

For details on the operating temperature and humidity, see the
specifi cations. (p. 51)

Usage Notes

Handling the cables

WARNING

To prevent electric shock, when measuring the
voltage of a power line use a test lead that satisfi es
the following criteria:

• Conforms to safety standards IEC61010 or EN61010

• Of measurement category II or III

• Its rated voltage is higher than the voltage to be
measured

All of the optional test leads for this instrument
conform to the safety standard EN61010. Use a test
lead in accordance with its defi ned measurement
category and rated voltage.

CAUTION

• Avoid stepping on or pinching the cable, which could

For the test leads supplied with the instrument or the options to be connected
to the instrument, see the following information.

damage the cable insulation.

• To avoid damaging the cables, do not bend or pull the
leads and the probe bases.

The ends of the test leads are sharp. Be careful to avoid
injury.

Reference

(p. 43)

Handling the strap

Those with medical electronics such as pacemakers
should not use the Z5004 Magnetic Strap. Nor should
such persons approach the Z5004. It is extremely
dangerous. The electronics may not operate properly
and the life of the operator may be put at great risk.

• Do not use the Z5004 in locations where it may
be exposed to rainwater, dust, or condensation. In
those conditions, the Z5004 may be decomposed or
deteriorated. The magnet adhesion may be diminished.
In such case, the instrument may not be hung in place
and may fall.

• Do not bring the Z5004 near magnetic media such
as fl oppy disks, magnetic cards, pre-paid cards, or
magnetized tickets. Doing so may corrupt and may
render them unusable. Furthermore, if the Z5004 is
brought near precision electronic equipment such as
PCs, TV screens, or electronic wrist watches, they may
fail.

Precautions during measurement

WARNING

If the instrument is used in locations where the rating
indicated on the instrument or probes is exceeded,
the instrument may be damaged resulting in personal
injury. Do not use the instrument in such locations.
See “Measurement categories” (p. 7).

• With regard to the 10 A range, the maximum input
current is 10 A DC/10 Arms AC. Supplying a current
in excess of the maximum input may damage the
instrument and result in personal injury. Do not
supply current in excess of the specifi ed limit.

Observe the following to avoid electric shock and/or
short circuits.

• Hazardous voltage may be generated in a free
measurement terminal. Do not touch the free
terminal.

• Use only test leads and optional equipment
specifi ed by our company.

• Do not allow the metal part of the test lead to touch
any exposed metal, or to short between 2 lines.
Never touch the metal end.

• When connecting the clip-type test lead to the
active terminal, do not allow the lead to touch any
exposed metal, or to short between 2 lines.

12

CAUTION

• Do not input voltage or supply current exceeding the
specifi ed measurement range. Doing so may damage
the instrument.

• During the continuity chec k , diode test, or measureme nt
of resistance or electrostatic capacity, measurement
signals are generated in the terminals of the instrument.
Depending on the target for measurement, the
measurement signal may cause damage.
Seeing “Measurement current” and “Open circuit
voltage” in the accuracy table (p. 55), check, in advance,
that there are no adverse effects of the measurement
current and the open circuit voltage.

Inserting/Replacing Batteries

2.2 Inserting/Replacing Batteries

Before using the instrument for the fi rst time, insert 2 R6P
manganese batteries or LR6 alkaline batteries. Before
measurements, check that the battery level is suffi cient. When the
battery charge is low, replace the batteries.

WARNING

To avoid el e ctri c s hock, disconnect the test leads from
the object to be measured before re p l ac ing the batteries.

To avoid the possibility of explosion, do not short
circuit, charge, disassemble, or incinerate batteries.

After battery replacement but before u sing the
instrument, reattach and screw down the battery cover.

CAUTION

Poor performance or damage from battery leakage
could result. Observe the cautions listed below.

• Do no mix new and old batteries, or different types of
batteries.

• Be careful to observe the battery polarity during installation.

• Do not use batteries after their recommended expiry date.

• Do not allow used batteries to remain in the instrument.

• To avo i d corrosion from b attery leakage an d /o r damage to
the instrument, remove the batteries from the instrument
if it is to be kept in storage for an extended peri od.

24

Inserting/Replacing Batteries

• lights up when the batteries are exhausted. The accuracy is not
guaranteed. Replace the battery immediately.

Using T est Leads

2.3 Using Test Leads

The L9206 Test Leads supplied with the instrument are used for
measurements.
Depending on measurement locations, use our optional
measurement cables. For details on the optional items, see “Options
(sold separately)” (p. 2).

DANGER

To avoid electric shock, do not short circuit the line on
which voltage is applied at the tip of the test lead.

WARNING

•

To prevent a short circuit accident, be sure to use the test leads
with the sleeves attached when performing measurements in the
CAT III measurement category. (See “Measurement categories”
(p. 7))

• If the sleeves are inadvertently removed during measurement,

stop the measurement.

• When connecting the lead, use the correct voltage measurement

terminal (V terminal) and current measurement terminal (A
terminal). If an incorrectly connected lead is used, the instrument
may be damaged or short circuit accidents may occur.

• Use only test leads and optional equipment specifi ed by our

company.

26

CAUTION

• To ensure safe operation, use only test leads specifi ed
by our company.

• When carrying out measurements with the sleeves in
place, be careful to avoid damaging the sleeves.

• The tips of the metal pins are sharp and may cause
injury. Do not touch the tips.
