How to Use a LCR Meter
Measurement frequency: Since the reactance is a function of frequency, your choice of measurement frequency should reflect the usage of the component. For capacitors, larger values (tens to hundreds of uF or more) are often used in power supply filtering applications, so should be tested at twice the line frequency.
How to measure capacitors/Test a Capacitors (8): How can I measure …
A. Insulation Resistance (IR) is the extent to which the dielectric material in a capacitor resists leakage current. It is the resistance of the dielectric material itself*1. IR is measured by leakage current. Knowing the leakage current and applied voltage, the insulation resistance can be calculated based on the ohm''s law.
