ACSURACY

OF THE

READINE

The accuracy

or

better

the

class

of

our

Supertester 680

R

is

1% in

D.C.

and

2% in

A.C.

According

to

the

international

rules

in

force

the

accuracy

of

an

indicating instrument

(the

to

called

«class

of

the

instrument»)

is

given

as an

abs0lute

percentage

and therefore

the

maximums

permissible reading

error

is

always referred

to

the

accuracy percentage

guaranieed

by

the

Producer referred

t0

the

full

scale

value.

For

instance:

let

us

examine

an

instrument

guaranteed

by the

producer

as

a

«class

2

instrument»

for

the

range

250 Volt

full

scale

value;

in this

case

the

maximum

permissible

error

+

Zok

is

to

be

referred

to

the

full

scale

value

that,

in

the

case

of

the

range

250

V

corresponds

t0

an

absolute

value

of

5

Volts.

According

to

the

international

rules and what

previously

said,

the

instrument

can

be

considered belonging

to

the

class

2

instrument,

only

if

the error

is

not

higher

than

i-

5

volts

in

any

point

of

the

scale.

That

is, the

instrument belongs

to

such

an

accuracy

class

(2%)

if it

for

instance,

indicates

255

or

245

instead

of

250, 105

or 95

instead

of

10C;

15

or

25

instead

of

20.

From

this

it

can

be

seen

that the

error, as

a

relative

percentage

is

increasing m0re

and more

in

the

initial

part

of

the

scale; as

a

consequence,

in

0rder

to

have

the

most

accurate readings

it

is

always

advisable

to

choose,

while

us!ng

a

Tester,

the

most convenient range

so

that

the

reading

is

carried

out

rnost

preferentially

in the

end scale

area.

According

to

the

main international rules,

the

control

0f

the

accuracy

is

to

be

carried

out

with

the

instrument

lying

orizontally,

at

a 20.C

temperature

and,

in

the

case

of

measurement

in

A.C.,

with

sinusoidal current.

lf

the

above mentioned

c0nditi0ns

change,

for

the

accurate

c0ntrol

0f

class

accuracy, the

!nterferences

due

to

such variations

will

have

to

be taken

into

account.
