Section IV Model 4262A
Paragraph 4-12
PERFORMANCE TESTS
4-12.
DISSIPATION
FACTOR
CONFIRMATION
CHECK
DESCRIPTION:
This
test
verifies
that
a
tested
4262A
satisfies
dissipation
factor
measurement
ac-
curacies.
Only
one
Dissipation
Factor
(D
=
1.8)
is
checked
for
120Hz,
1kHz
and
10kHz
in
this
check
because
only
one
detecting
phase
needs
to
be
checked.
All
other
factors
influencing
D
accuracy
were
checked
in
paragraph
4-10.
Note
Dissipation factor accuracy for only one D
standard which has a D value of approximate-
ly
1.8
need
be
proved
to
guarantee
D
accura-
cy.
This
test
also
verifies
that
4262A
correctly
calculates Q factor as a reciprocal number of
Dissipation Factor. Only one Q factor corres-
ponding to a D value of approximately 1.8 is
checked
in
this
fest.
D
accuracy
in
measuring
inductance does not need to be checked
because detecting phase accuracy is equated
with that for capacitance measurement.
