Figure 24: Connection schematics for the capacitor leakage and insulation resistance tests
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.
