Measurement categories

This instrument complies with CAT II safety requirements.

To ensure safe operation of measurement instruments, IEC 61010 establishes safety standards for various electrical

environments, categorized 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,

household appliances, etc.)

CAT II covers directly measuring electrical outlet recep-

tacles.

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).

Using a measurement 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.

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.

Operating Precautions

Follow these precautions to ensure safe operation and to obtain the full benefits of the various

functions.

Be sure to observe the operating and storage temperature and humidity ranges specified for

the instrument:

• Operating temperature and humidity: 0°C to 40°C, 40% to 80% RH (non-condensing)

• Storage temperature and humidity: -20°C to 55°C, 10% to 80% RH (non-condensing)

The instrument should be installed on a level surface. Use of the device on an inclined sur-

face may prevent readings from being properly recorded or recording paper from folding prop-

erly.

Operating Precautions

Preliminary Checks

• Before using the instrument for the first time, verify that it operates normally to

ensure that no damage occurred during storage or shipping. If you find any dam-

age, contact your dealer or Hioki representative.

• Before using the instrument make sure that the insulation on the power cord is

undamaged and that no bare conductors are improperly exposed. Using the instru-

ment in such conditions could cause an electric shock, so contact your dealer or

Hioki representative for repair.

• Before using the instrument, make sure that the insulation on cables is undamaged

and that no bare conductors are improperly exposed. Avoid using any cables

showing damage as they may cause electric shock.
