The following figure shows schematic diagrams. One shows measuring the leakage current of a
capacitor. The other shows measuring the insulator resistance between two conductors of a coaxial
cable.

The following figures show the rear-terminal connections to the device under test (DUT) for these
applications. If capacitor leakage measurements are noisy, you may need to use the high
capacitance mode or add a low leakage forward-biased diode in series with the capacitor.
