Accuracy of D
When D
x
(tested value of D) ≤ 0.1, the accuracy of D
e
is given by the formula below:
D
e
=
When D
x
> 0.1, D
e
should be multiplied by (1+D
x
).
Accuracy of Q
The accuracy of Q is given by the formula below:
Q
e
=
Where, Q
x
is the value of the tested Q.
D
e
is the accuracy of D.
Above formula should be used when Q
x
×D
e
< 1.
Accuracy of θ
The accuracy of θ is given by the formula below:
θe = [deg]
Accuracy of G
When D
x
(tested value of D) ≤ 0.1, the accuracy of G is given by the formula below:
G
e
= B
x
×D
e
[S]
B
x
= 2πfC
x
for capacitance
B

= for inductance
Where, B
x
is the value of tested B with the unit [S].
C
x
is the value of tested C with the unit [F].
L
x
is the value of tested L with the unit [H].
D
