Hi!
My new Rigol DHO924S arrived these days. With the extra ground lead, since the new scopes are not grounded directly through the power supply anymore. Now I was wondering what actually is required for this ground connection? The manual isn't very specific and searching with Google just reveals a plethora of tips on "how not to blow your scope".
Is it enough to use a ground plug with 1 MOhm resistance for ESD protection, or does it require a low resistance connection to ground? I found different products and am wondering what is the right choice.
Many greetings!
Remo
