The measuring tip is now held first on the left-hand and then on the right-hand 4.4 KV connector of the transformer for approx. 5s It is necessary to ensure that the tip stays on each contact for the full 5s. Attention! All marked components inside the oscillator are short circuited to ground using the measuring tip.
