Safety Notes
Safety Symbols
This manual contains information and warnings essential for safe
operation of the meter and for maintaining it in safe operating con-
dition. Before using it, be sure to carefully read the following safety
precautions.
This meter is designed to comply with IEC 61010 Safety Stan-
dards, and has been thoroughly tested for safety prior to
shipment. However, mishandling during use could result in
injury or death, as well as damage to the meter. Be certain
that you understand the instructions and precautions in the
manual before use. We disclaim any responsibility for acci-
dents or injuries not resulting directly from meter defects.
In the manual, the symbol indicates particularly
important information that the user should read before
using the meter.
The symbol printed on the meter indicates that the
user should refer to a corresponding topic in the manual
(marked with the symbol) before using the relevant
function.
Indicates DC (Direct Current).
Indicates AC (Alternating Current).
Indicates a double-insulated device.
Indicates that the instrument may be connected to or dis-
connected from a live circuit.

The following symbols in this manual indicate the relative impor-
tance of cautions and warnings.
Other Symbols
Accuracy
We define measurement tolerances in terms of f.s. (full scale), rdg.
(reading) and dgt. (digit) values, with the following meanings:
f.s. (maximum display value or scale length)
The maximum displayable value or scale length. This is usually the
name of the currently selected range.
rdg. (reading or displayed value)
The value currently being measured and indicated on the measur-
ing meter.
dgt. (resolution)
The smallest displayable unit on a digital measuring meter, i.e., the
input value that causes the digital display to show a "1" as the
least-significant digit.
Indicates that incorrect operation presents an
extreme hazard that could result in serious injury or
death to the user.
Indicates that incorrect operation presents a signifi-
cant hazard that could result in serious injury or
death to the user.
Indicates that incorrect operation presents a possi-
bility of injury to the user or damage to the meter.
Indicates advisory items related to performance or
correct operation of the meter.
Indicates the prohibited action.
❖Indicates the reference.

4Safety Notes
Measurement categories (Overvoltage categories)
This device complies with CATIII (600 V), CATII (1000 V) safety
requirements.
To ensure safe operation of measurement devices, IEC 61010
establishes safety standards for various electrical environments,
categorized as CAT I to CAT IV, and called measurement catego-
ries. These are defined as follows.
Higher-numbered categories correspond to electrical environments
with greater momentary energy. So a measurement device
designed for CAT III environments can endure greater momentary
energy than a device designed for CAT II.
Using a measurement device in an environment designated with a
higher-numbered category than that for which the device is rated
could result in a severe accident, and must be carefully avoided.
Never use a CAT I measuring device in CAT II, III, or IV environ-
ments.
The measurement categories comply with the Overvoltage Cate-
gories of the IEC60664 Standards.
CAT I Secondary electrical circuits connected to an AC
electrical outlet through a transformer or similar
device.
CAT II Primary electrical circuits in equipment connected to
an AC electrical outlet by a power cord (portable
tools, household appliances, etc.)
CAT III Primary electrical circuits of heavy equipment (fixed
installations) connected directly to the distribution
panel, and feeders from the distribution panel to out-
lets.
CAT IV The circuit from the service drop to the service
entrance, and to the power meter and primary over-
current protection device (distribution panel).

Usage Notes
Follow these precautions to ensure safe operation and to obtain
the full benefits of the various functions.
Setting Up the 3290-10
• This meter should be installed and operated indoors only,
between 0 and 40°C and 80% RH or less.
• Do not use the meter where it may be exposed to corrosive or
combustible gases. The meter may be damaged.
• Do not store or use the meter where it could be exposed to
direct sunlight, high temperature or humidity, or condensation.
Under such conditions, the meter may be damaged and insula-
tion may deteriorate so that it no longer meets specifications.
• This meter is not designed to be entirely water- or dust-proof. Do
not use it in an especially dusty environment, nor where it might
be splashed with liquid. This may cause damage.
• Do not use the meter near a source of strong electromagnetic
radiation, or near a highly electrically charged object. These may
cause a malfunction.
• To avoid damage to the meter, protect it from physical shock
when transporting and handling. Be especially careful to avoid
physical shock from dropping.
Avoid the follow-
ing:
Dust
Electomagnetic
radiation
Direct
sunlight
Corrosive or
explosive gases
High temperature
High humidity
Impact, dropping
Correct measurement may be impossible in the presence of
strong magnetic fields, such as near transformers and high-cur-
rent conductors, or in the presence of strong electromagnetic
fields such as near radio transmitters.

6Usage Notes
Before using the meter the first time, verify that it operates normally
to ensure that the no damage occurred during storage or shipping.
If you find any damage, contact your dealer or Hioki representative.
Preliminary Checks
Before using the meter, make sure that the insulation on the
probes is undamaged and that no bare conductors are
improperly exposed. Using the meter in such conditions
could cause an electric shock, so contact your dealer or
Hioki representative for repair.
• To avoid short circuits and potentially life-threatening haz-
ards, never attach the clamp to a circuit that operates at
more than 600V, or over bare conductors.
• Clamp sensor should only be connected to the secondary
side of a breaker, so the breaker can prevent an accident if
a short circuit occurs. Connections should never be made
to the primary side of a breaker, because unrestricted cur-
rent flow could cause a serious accident if a short circuit
occurs.
• To avoid electric shock, do not touch the portion beyond
the protective barrier during use.
• Do not allow the meter to get wet, and do not take measure-
ments with wet hands. This may cause an electric shock.
• To avoid electric shock when measuring live lines, wear
appropriate protective gear, such as insulated rubber
gloves, boots and a safety helmet.

• The maximum continuous-input limit is obtained from the tem-
perature increase due to self-heating during measurement. To
prevent damage to the clamp-on sensor, do not input a current
exceeding this limit.
• The maximum continuous-input limit varies depending on the
clamp-on sensor and the frequency of the current to be mea-
sured.
❖Maximum continuous-input limit varies:
See Section 6.3 "CLAMP ON AC/DC SENSOR Specifications" (page 116)
Each sensor’s derating acording to frequency
•The indicator appears when battery voltage becomes low.
Replace the batteries as soon as possible.
• After use, always turn OFF the power.
• Attach the clamp around only one conductor. Single-phase (2-
wire) or three-phase (3-wire) cables clamped together will not
produce any reading.
OK
Handling the Clamp Sensors
• The ends of the clamp sensor are very delicate. Be careful not to
drop the sensor or subject it to impact. If the sensor is deformed
or the contact surfaces of the clamps are damaged, the mea-
surement may not be accurate.
• Be careful to avoid dropping the clamps or otherwise subjecting
them to mechanical shock, which could damage the mating sur-
faces of the core and adversely affect measurement.
• The top part of the clamp sensor above the barrier (including the
clamps, but not the lever) is provided with double insulation to
ensure safety. Be careful not to drop the sensor or otherwise
subject it to impact. A damaged sensor may result in electric
shock during measurement. In case of sensor damage, contact
us immediately for repair or discard the damaged sensor to
avoid subsequent use.

Overview
The 3290-10 CLAMP ON AC/DC HiTESTER is used with the 9691,
9692, or 9693 CLAMP ON AC/DC SENSOR. These sensors are
interchangeable and any model can be used with the 3290-10.
The 3290-10 automatically detects the sensor connected and sets
up the appropriate range. When combined with the 9691, 9692, or
9693 Sensor, the 3290-10 HiTESTER can perform DC, AC, and
AC+DC measurement of a live power line. In addition, current inte-
gral and duty measurement functions are provided.
As well as operating from batteries or AC adapter, operation from
an external DC power source is supported for long-term measure-
ments.
See page 139 for details of the differences with the Model 3290
CLAMP ON AC/DC HiTESTER.
