Introduction
Thank you for purchasing the HIOKI 3246-60 PENCIL HiT-
ESTER. To obtain maximum performance from the product,
please read this manual first, and keep it handy for future refer-
ence.
Overview
The 3246-60 is a pencil-shaped digital multimeter designed to
measure DC/AC voltage and resistance, and conduct continuity
and diode checks. Compact, safe, and easy to use, the 3246-60
meets all CATIV 300 V, CATIII 600 V safety requirements. Probe
leads are wound around the protrusions on the rear. The unit also
features a built-in light to illuminate the object to be measured.
Initial Inspection
When you receive the product, inspect it carefully to ensure
that no damage occurred during shipping. If damage is evident,
or if it fails to operate according to the specifications, contact
your dealer or Hioki representative.
Preliminary Checks
• Before using the product the first time, verify that it operates
normally to ensure that the no damage occurred during stor-
age or shipping. If you find any damage, contact your dealer
or Hioki representative.
• 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.
Using the product in such conditions could cause an electric
shock, so contact your dealer or Hioki representative for repair.
Maintenance and Service
• To clean the product, wipe it gently with a soft cloth moist-
ened with water or mild detergent. Never use solvents such
as benzene, alcohol, acetone, ether, ketones, thinners or
gasoline, as they can deform and discolor the case.
• If the product seems to be malfunctioning, confirm that the
batteries are not discharged, and contact your dealer or Hioki
representative.
Follow these precautions to ensure safe operation and to
obtain the full benefits of the various functions.
Measurement categories
This product complies with CAT IV (300 V), CAT III (600 V), CAT II
(600 V) safety requirements.
To ensure safe operation of measurement products, IEC 61010 estab-
lishes safety standards for various electrical environments, catego-
rized as CAT II to CAT IV, and called measurement categories.
CAT II: Primary electrical circuits in
equipment connected to an
AC electrical outlet by a power
cord (portable tools, house-
hold appliances, etc.) CAT II
covers directly measuring
electrical outlet receptacles.
CAT III:Primary electrical circuits of
heavy equipment (fixed installations) connected directly to the dis-
tribution panel, and feeders from the distribution panel to outlets.
CAT IV:The circuit from the service drop to the service entrance, and
to the power meter and primary overcurrent protection device
(distribution panel).
Using a measurement instrumentin 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.
Use of a measurement instrument that is not CAT-rated in CAT II to
CAT IV measurement applications could result in a severe accident,
and must be carefully avoided.

Usage Notes
• To avoid electric shock, do not allow the product to get
wet, and do not use it when your hands are wet.
• Do not use the product where it may be exposed to cor-
rosive or combustible gases. The product may be dam-
aged or cause an explosion.
• To avoid electric shock when measuring live lines, wear
appropriate protective gear, such as insulated rubber
gloves, boots and a safety helmet.
• Do not store or use the product where it could be exposed
to direct sunlight, high temperature or humidity, or conden-
sation. Under such conditions, the product may be damaged
and insulation may deteriorate so that it no longer meets
specifications.
• This product is not designed to be entirely water- or dust-proof.
To avoid damage, do not use it in a wet or dusty environment.
• This product is designed for indoor use, and operates reli-
ably from 0°C to 40°C.
• To avoid damage to the product, protect it from vibration or
shock during transport and handling, and be especially care-
ful to avoid dropping.
• Do not use the product near a device that generates a strong
electromagnetic field or electrostatic charge, as these may
cause erroneous measurements.
• To avoid damaging the test leads, do not bend or pull the leads.
• If the protective functions of the product are damaged, either
remove it from service or mark it clearly so that others do not
use it inadvertently.
• Accurate measurement may be impossible in the presence of
strong magnetic fields, such as near transformers and high-
current conductors, or in the presence of strong electromag-
netic fields such as near radio transmitters.
• To avoid battery depletion, turn the Function Selector OFF
after use (the Auto Power Save feature consumes a small
amount of current).
• The
indicator appears when battery voltage becomes low.
Replace the batteries as soon as possible.
• To avoid corrosion from battery leakage, remove the batteries
from the product if it is to be stored for a long time.

Removable sleeves can be attached to the metal pins at
the ends of the test leads. To prevent a short circuit acci-
dent, be sure to use the test leads with the sleeves
attached when performing measurements in the CAT III
and CAT IV measurement categories. Remove the sleeves
from the test leads when performing measurements in the
CAT II measurement category.
For details on measurement categories, see "Measure-
ment categories") in the instruction manual.
• The tips of the metal pins are sharp, so take care not to in-
jure yourself.
• When performing measurements with the sleeves attached,
be careful to avoid damaging the sleeves.
• If the sleeves are inadvertently removed during measure-
ment, be especially careful in handling the test leads to
avoid electric shock.
