This instrument has been calibrated to operate with the provided mag-

netic field sensor and should be used only with this sensor. Thus if

multiple instruments are used, Before use make sure that the match-

ing number (up to the hyphen) on the tester and the sensor are identi-

cal.

This manual contains information and warnings essential for safe opera-

tion of the instrument and for maintaining it in safe operating condition.

Before using it, be sure to carefully read the following safety precautions.

Safety Symbols

The following symbols in this manual indicate the relative importance of

cautions and warnings.

Safety Information

This instrument 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 the instrument. Using the instru-

ment in a way not described in this manual may negate the pro-

vided safety features.

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 instrument/ defects.

In the manual, the symbol indicates particularly impor-

tant information that the user should read before using

the instrument.

The symbol printed on the instrument indicates that

the user should refer to a corresponding topic in the man-

ual (marked with the symbol) before using the relevant

function.

Indicates DC (Direct Current).

Indicates AC (Alternating Current).

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 instru-

ment.

Indicates advisory items related to performance or

correct operation of the instrument.

Symbols for Various Standards

Other Symbols

WEEE marking:

This symbol indicates that the electrical and electronic

appliance is put on the EU market after August 13, 2005,

and producers of the Member States are required to dis-

play it on the appliance under Article 11.2 of Directive

2002/96/EC (WEEE).

Indicates that the product conforms to regulations set out

by the EU Directive.

p. ) Indicates the location of reference information.

* Indicates that descriptive information is provided below.

Indicates a prohibited action.

Measurement Categories

The applicable measurement category is determined by the input mod-

ule being used.

To ensure safe operation of measurement instruments, IEC 61010

establishes 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, household

appliances, etc.)

CAT II covers directly measuring electrical outlet receptacles.

CAT III : Primary electrical circuits of heavy equipment (fixed installa-

tions) 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.

Do not touch high voltage lines with the

sensor or the instrument. They are not

insulated and the application of high volt-

age to this instrument may expose testing

personnel to high voltage that may at

worst lead to electric shock and death.
