6.2.2.2.1 Definition of ESD parameters
Contact Discharge = Discharge via the „ESD Relay“ tip. The relay tip must be on top of the ESD discharge
network. The relay tip must contact the EUT.
Air Discharge = Discharge via the adapter „finger“. The discharge occurs as a spark between the finger
and the EUT.
Pulse Counter = On discharge only
Only the impulses whereas the voltage of the discharge capacitor (150 pF) droplower than 10 % of the
charging voltage are counted.
Which discharge method must be used? See Chapter 5.4.2.
