The accuracy of R is defined as:
s
R = X ×D

X = 2 fL =
x x
2 fC
Where:
X is the measured X value[ ].
x
C is the measured C value[F].
x
L is the measured L value[H].
x
D is .
e
F is the measuring frequency.
The following will show how to decide the basic
accuracy, A:
A is 0.05:
When the measuring signal is 0.4V
and the measurement speed is slow or medium.
A is 0.1:
When the measuring signal is 0.4V
and the measurement speed is fast.
When the measuring signal is V
the basic accuracy, A, should be calculated according to
the following description:
Write down the basic accuracy, A, for the
measurement speed currently being used and then
write down the correction factor, A
the amplitude of the measuring signal being
currently used (see Figure 13-2). Let A be multiplied
by A to get the actual basic accuracy, A, for that
r
moment. V represents the amplitude of the
s
measuring signal.
