IMPEDANCE EXPLANATION
•
Impedance is compromised of two
base components – Resistance
and Reactance.
•
This LCR meter is capable of
measuring both Resistance and
Reactance.
•
Reactance varies in proportion to
the frequency of the AC circuit.
•
Impedance forms an imaginary
vector comprised of Resistance
R (real) and Reactance X
(imaginary) with Impedance
Z=R+jX, which can also be
represented by amplitude |Z| and
phase angle θ, which can be seen
in the diagram.
•
If the phase angle θ > 0, the reactance is inductive in nature, if θ < 0 the reactance
is capacitive in nature.
MEASUREMENT MODE
Impedance can be measured in serial or parallel mode. Under parallel mode,
impedance Z can be expressed in relation with the admittance Y and Y=G+jB. G is
conductance and is B admittance.
Serial Measurement
Rˢ: Serial mode of resistance
Xˢ: Serial mode of reactance
Cˢ: Serial mode of capacitance
Lˢ: Serial mode of inductance
Rˢ
jXˢ
Z = Rˢ + jXˢ
