measuring insulation resistance of capacitors
This situation could be improved by shielding the device under test (DUT) and the test leads from the AC noise. Indeed, at high values of resistance (above 1GW) low noise shielded cables are highly recommended. The real solution to the problem of capacitor testing comes from remembering the cause - high AC gain.
