(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 the full length of

the scale. This is usually the maximum value of the

currently selected range.

rdg. (reading or displayed value)

The value currently being measured and indicated

on the measuring product.

dgt. (resolution)

The smallest displayable unit on a digital measuring

product, i.e., the input value that causes the digital

display to show a "1".

Measurement categories (Overvoltage

categories)

This product conforms to the safety requirements for

CAT II (1000V), CATIII (600V) measurement

products.

To ensure safe operation of measurement product,

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).
