• Test tip with spring contact and corrugated contact surface, for contacting small surfaces
• Tests for air and contact discharge according to IEC / EN 61000-4-2
• SESD 3027 is to be only used for Contact discharge
• 75mm Long

In this method, the test probe of the generator is placed directly on the test specimen. The actual "pulse release" takes place via a relay contact and reduces the influence factors such as approach speed, humidity, temperature, etc. The contact discharge is reproducible and therefore the preferred test method.
