C+R MODE:
Capacitance is shown on the Primary Display and the
parallel resistance R, is shown on the Secondary Display. The units
of capacitance are pF, nF, or µF. Resistance units are Ω or kΩ. Parallel
(C < 500 pF) or serial (C > 500 pF) equivalent circuit diagram is used.
C+D MODE:
Capacitance is shown on the Primary Display and
dissipation factor D on the Secondary Display. The capacitance
is either the equivalent series or parallel capacitance of the
DUT. The units of capacitance are pF, nF, μF or mF. D is the
ratio of the real part of the impedance to the imaginary part
of the impedance, or 1/Q. D is dimensionless and the same
for series and parallel representations. A good capacitor has
a large C (imaginary) and a small R (real) and thus a low D.
|Z| MODE:
The Impedance of the component is shown
on Primary Display. Units are mΩ, Ω, kΩ, or MΩ.
ESR MODE:
The equivalent series resistance of the capacitor is
shown on the Primary Display. ESR units are mΩ, Ω, kΩ, or MΩ.
AUTO MODE:
ST determines which component model is the most
accurate representation of the DUT and automatically selects the
appropriate parameter set. The determination is made as follows:
• For |Q| < 0.15 the R mode is selected.
• For Q > +0.15 the L+R or L+Q mode is selected (depends on user settings).
• For Q < -0.15 the C+R or C+D mode is selected.
• For C < 500 pF Parallel circuit diagram (Rp) is used.
• For C >= 500 pF Serial circuit diagram (Rs) is used.
