2Safety Notes

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.

Safety Notes 3

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).
