Safety Information
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
•Using a measuring instrument in an environment
designated with a higher-numbered category than
that for which the instrument is rated could result in
a severe accident, and must be carefully avoided.
•Never use a measuring instrument that lacks
category labeling in a CAT II to CAT IV measurement
environment. Doing so could result in a serious
accident.
This instrument conforms to the safety requirements for CAT III 600 V
measuring instruments.
CAT II: When directly measuring the electrical outlet receptacles of the
primary electrical circuits in equipment connected to an AC electrical
outlet by a power cord (portable tools, household appliances, etc.)
CAT III: When measuring the primary electrical circuits of heavy equipment
(xed installations) connected directly to the distribution panel, and
feeders from the distribution panel to outlets.
CAT IV: When measuring the circuit from the service drop to the service
entrance, and to the power meter and primary overcurrent
protection device (distribution panel).

Operating Precautions
Operating Precautions
Observe the following precautionary information to ensure that the
instrument can be used safely and in a manner that allows it to
perform as described in its specications.
Use of the instrument should conrm not only to its specications,
but also to the specications of all accessories, options, batteries,
and other equipment in use.
DANGER
•For your safe operation, do not connect any test
lead to the primary of the distribution panel.
•Do not short-circuit two wires to be measured by
bringing the test leads into contact with them. Arcs
or such grave accidents are likely to occur.
•To avoid short circuit or electric shock, do not touch
the metal part of the connecting test lead tip.
•To avoid electric shock, be careful to avoid shorting
live lines with the test leads tip.
If the test lead or the instrument is damaged, there
is a risk of electric shock. Perform the following
inspection before using them:
•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 could result in electric
shock. Replace the test leads with those specied
by Hioki.
•Verify that the instrument operates normally to
ensure that no damage occurred during storage
or shipping. If you nd any damage, contact your
authorized Hioki distributor or reseller.

Operating Precautions
WARNING
To avoid electric shock, short circuits and damage to
the instrument, observe the following precautions:
•Check the position of the rotary switch before
taking measurements.
•Disconnect the test leads from the measuring object
before switching the rotary switch.
•Do not use the instrument with circuits that exceed
its ratings or specications. Doing so may damage
the instrument, resulting in electric shock.
•Use only the specied test leads. Use of any test
lead not specied by Hioki does not allow safe
measurements.
•To prevent electrical accidents, turn off the circuit
before connecting the test leads.
• To avoid electric shock, do not exceed the lower of
the ratings shown on the instrument and test leads.
CAUTION
• The cable is hardened under the 0°C or colder
environment. Do not bend or pull it to avoid tearing its
shield or cutting cable.
• The protection rating for the enclosure of this device
(based on EN 60529) is IP40*.
* IP40:
This indicates the degree of protection provided by the enclosure of
the device against use in hazardous locations, entry of solid foreign
objects, and the ingress of water.
4: Protected against access to hazardous parts with wire measuring 1.0 mm
in diameter.
0: The equipment inside the enclosure is not protected against the harmful
effects of water.

Operating Precautions
Installing the instrument
WARNING
Installing the instrument in inappropriate locations
may cause a malfunction of instrument or may give
rise to an accident. Avoid the following locations.
• Exposed to direct sunlight or high temperature
• Exposed to corrosive or combustible gases
• Exposed to a strong electromagnetic eld or
electrostatic charge
• Near induction heating systems (such as high-
frequency induction heating systems and IH
cooking equipment)
•Susceptible to vibration
• Exposed to water, oil, chemicals, or solvents
• Exposed to high humidity or condensation
• Exposed to high quantities of dust particles
CAUTION
Do not place the instrument on an unstable table or an
inclined place. Dropping or knocking down the instrument
can cause injury or damage to the instrument.
Precautions when transporting the instrument
During shipment of the instrument, handle it carefully so that it is not
damaged due to a vibration or shock.

Operating Precautions
Handling the Instrument
DANGER
Persons wearing electronic medical devices such
as a pacemaker should not use the 9804-01, 9804-02
Magnet Adapter. Such persons should avoid even
proximity to the 9804-01 and 9804-02, as it may
be dangerous. Medical device operation could be
compromised, presenting a hazard to human life.
CAUTION
To avoid damage to the instrument, protect it from physical
shock when transporting and handling. Be especially
careful to avoid physical shock from dropping.
Test leads
CAUTION
• Removable sleeves are attached to the metal pins
at the end of the test leads. 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. Remove the sleeves before
starting CAT II measurements. You can use the test
leads with the sleeve removed for secondary side of
the circuit breakers turned off. (See “Measurement
Categories” (p. 8))
• If the sleeves are inadvertently removed during
measurement, stop the measurement. (p. 26)

1Overview
1.1 Product Overview
This instrument is an insulation ohmmeter that shortens work times
associated with insulation testing. It is not designed for use on
manufacturing lines and should not be used in such applications.
For manufacturing line applications, use the ST5520 Insulation
Tester.
High-speed response
• Considerably improved response time compared to previous models.
• The instrument can be used like models with a meter needle.
Enhanced comparator function
• Can be used similarly to the continuity check with a tester due to judgment
after the start of measurement being extremely short.
• The backlight lights up in red for a FAIL judgment (defective).
Low variation in measured values
• The instrument generates little variation in measured values when used in a
typical measuring environment.
Easy-to-view display
• Backlight source is a white high-intensity LED.
• Wide viewing angle LCD
High-accuracy voltage measurement function
• The instrument incorporates a DC/AC voltmeter with the same accuracy as
a card tester.
• There is no need to switch to a card tester when you need to measure
voltage.
PVΩmeasurement function (IR4053 and IR4055 only)
• Insulation resistance can be measured accurately for solar battery panel.
