Equivalent Series Resistance (ESR). To measure series resistance of capacitors, use the Rs function.
Series resistance will be displayed on the front panel.
Series Capacitance. The Ls function can be used to measure series capacitance. (The capacitor is
measured with a constant current rather than a constant voltage.) A negative reading will be shown,
and the following equation must be used to convert the “-Ls” readings to the “Cs” values:
Where: f=frequency in hertz
Cs= series capacitance in farads
Ls=series inductance in henrys (ignore sign)
Dissipation factor (D). The D of large value electrolytic capacitors can be determined using the Ls and Rs
functions using the same range. The following equation converts the Rs and Ls, in counts (ignore the
Sign and decimal point), to D values:
Where: D= dissipation factor
Rs= equivalent series resistance reading in counts
Ls= series inductance in counts
