Measurement of separation among the installation circuits

Insulation or safety transformer making
the separation among the circuits.

Test among the
active parts.
Connect a test
lead

of

the

instrument to one
of

the

two

conductors of the
separate

circuit

and the other to
one

of

the

conductors of a
no

separate

circuit.

Test

between

the active parts
and the earth.
Connect a test
lead

of

the

instrument to one
of

the

two

conductors of the
separate

circuit

and the other to
the
