Safety Note s

Safety Notes

This meter is designed to comply with IEC 61010 Safety Stan­dards, 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 th e meter. Be certain
that you understand the instructions and precautions in the
manual before use. We disclaim any respon sibility for acci
dents or injuries not resulting directly from meter defects.

Safety Symbols

This manual contains information and warnings essential for safe
operation of the meter and for maintaining it in safe operating con­dition. Before using it, be sure to carefully read the following safety
precautions.

-

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 dis­connected from a live circuit.

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.

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 signifi­cant hazard that could result in serious injury or
death to the user.

Indicates that incorrect operation presents a possi­bility 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.

Safety Note s

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.

-

CAT I Secondary electrical circuits connected to an AC

CAT II Primary electrical circuits in equipment connected to

CAT III Primary electrical circuits of heavy equipment (fixed

CAT IV The circuit from the service drop to the service

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 w hich 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 environ­ments.
The measurement categories comply with the Overvoltage Cate­gories of the IEC60664 Standards.

Usage Notes

Avoid the follow­ing:

Corrosive or
explosive gases

High temperature
High humidity

Direct
sunlight

Electomagnetic
radiation

Dust

Impact, dropping

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 b e 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.

Usage Notes

Preliminary Checks

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.

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.

Measurement

• To avoid short circuits and potentially life-t hreatening haz­ards, never attach the clamp to a circuit that operates at
more than 600V, or over bare conductors.

• Clamp sensor should o nly be connected to the secondary
side of a breaker, so the breaker can preven t an a ccident if
a short circuit occurs. Connections should nev er be made
to the primary side of a breaker, because unrestricted cur
rent flow could cause a serious accide nt if a short circuit
occurs.

• To avoid electric shock, do not touch the portion be yond
the protective barrier during use.

Barrier

-

Do not get wet.

This model is the 9661

• Do not allow the meter to get wet, and do not take measure­ments 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.

Usage Notes

• The maximum continuous-input limit is obtained from the tem­perature 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 (2­wire) or three-phase (3-wire) cables clamped to gether 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 th e mating sur­faces 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 1

1.1 Product Overview

The 3290-10 CLAMP ON AC/DC HiTESTER is used with the 9691,
9692, or 9693 CLAMP ON AC/DC SE NSOR. 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 9 691, 9692, or
9693 Sensor, the 3290-10 HiTESTER can perform DC, AC, and
AC+DC measurement of a live pow er line. In addition, current inte
gral and duty measurement functions are provided.
As well as operating from batteries or AC adapte r, 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/D C HiTESTER.
