Re: Oscilloscope grounding question...


"legg"

How many scopes did go get with internal ground traces fused open?

** That should not happen with any scope that meets even basic electrical
safety requirements - one of which is that external metal parts ( like
the BNC sockets) must be connected to the AC supply ground terminal by
conductors of at least 1 sq. mm cross section.

Precludes the use of PCB traces alone to do the job.

Tek broke this rule with their very popular TDS210 / 220 series and had to
recall the whole lot.
