Measurement categories (Overvoltage categories)

This product conforms to the safety requirements for CAT I

measurement products.

To ensure safe operation of measurement products, IEC 61010

establishes safety standards for various electrical environments,

categorized as CAT I to CAT IV, and called measurement

categories. These are defined as follows.

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 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).

Higher-numbered categories correspond to electrical environments

with greater momentary energy, so a measurement product

designed for CAT III environments can endure greater momentary

energy than one designed for CAT II. Using a measurement

product in an environment designated with a higher-numbered

category than that for which the product is rated could result in a

severe accident, and must be carefully avoided.

Never use a CAT I measuring product in CAT II, III, or IV

environments.

The measurement categories comply with the Overvoltage

Categories of the IEC60664 Standards.

Precautions

___________________________________________________________________

DANGER The floating voltage between input terminals and

ground is 450V DC/AC. Attempting to measure

voltages exceeding 450V with respect to ground

could damage the product and result in personal

injury.

When voltages higher than 30 Vrms, 42.4 Vpeak or

battery circuits with more than 60 VDC are to be

measured, be sure to establish the floating state

first. Carrying out such measurements in the

grounded state involves the risk of electric shock.

When measuring batteries, always ensure sufficient

ventilation. Sometimes sparks may occur when the

test leads are connected to batteries, which can

ignite any accumulated inflammable gases such as

hydrogen.

To avoid electric shock accidents, when measuring

batteries being charged wear proper protective gear

such as rubber gloves.

WARNING

Do not allow the product to get wet, and do not take

measurements with wet hands. This may cause an

electric shock.

Do not use the product where it may be exposed to

corrosive or combustible gases. The product may be

damaged or cause an explosion.

Precautions

Follow these precautions to ensure safe operation and to

obtain the full benefits of the various functions.

___________________________________________________________________

Precautions

___________________________________________________________________

WARNING

Before using the product, make sure that the

insulation on the leads is undamaged and that no

bare conductors are improperly exposed. Using the

product in such conditions could cause an electric

shock, so contact your dealer or Hioki representative

for replacements. (Model 9460)

Be sure to connect the SOURCE and SENSE

terminals (banana plugs), and TEMP SENSOR

terminal (mini-plug) correctly. See Section 4.2,

"Measurement" for details of the connections.

To avoid injury or damage to the product, do not

attempt to measure AC voltage, or DC voltage

exceeding 50 V.

50 VDC max.

Do not apply a voltage between the SOURCE(+) and

SENSE(+) or SOURCE(-) and SENSE(-) terminals.

This could result in damage to the unit.

CAUTION 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.
