When the plug discharge test is performed using a voltage probe and oscilloscope for
direct measurement of the voltage decay, what probe impedance shall be used to ensure

If the relevant standard does not contain contradictory requirements, a voltage probe
having an input impedance of 100 M
or greater in parallel with an input capacitance of
