Decision approved at the
2009 CTL Plenary Meeting
Question:
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
uniform and comparable results?
  U$ r# u$ W/ e& YNote: IEC 60950-1/2005 specifies 100 M
± 5 M
in parallel with an input capacitance of 20pF ± 5 pF.
