Harry, Yes, you have to pick your battles. :-) We've done the same thing, it is sometimes quicker to change a procedure than to argue the validity. I remember an auditor not liking an ESD setup, regarding the VCP. I was injecting on the same side of the VCP that the ground lead was attached. The auditor stated something about the current path needs to cross the coupling plane for it to be a valid setup. There was no wording in the standard to that effect, but the example setup picture showed it that way. The ground lead, IMHO, is just a bleeder circuit to bring the VCP back to 0v before the next discharge, so it doesn't matter where it is attached. Now, in the latest version of the standard, one of the example setups show the lead on the same side as the ESD gun. I feel vindicated. :-) Bob R.

The deficiency was objected to the accreditation body but it was quicker to satisfy the auditor's whims rather than engage in an elongated discussion about the rights and wrongs...... Mea culpa - I never did follow up with the accreditation body - simply because there were more pressing things to take care of and the problem was fixed; well, until the next audit! <ht p://mail.yimg.com/a/i/mesg/tsmileys2/01.gif> .
