That makes sense. I will do that in the future. Thank you for the suggestion!
Keep in mind that when you screw up, you only have to answer to you.
As a professional Electronics Engineering Technician, working for Apple or Google, while they have plenty of money to buy stuff, if they order some expensive microprocessor board and I or any other tech blows it up
doing what you did, it will not bode well for our career with that company, if you know what I mean....
(so yes, we always check it BEFORE we throw the switch. Ideally, it is a two man operation where one person is operating the hardware and he requests a check by a second person to produce a witness that the voltage was in fact correct. When the person doing the QC says "yeah, it's good, your clear to turn on the power. " then he becomes the witness so if the boss says "Did anyone else check the power before you
turned it on ? " they are "off the hook" and the primary suspect becomes the board. (manufacturing defect)
Make sense ? Otherwise, it's just the one tech saying "But I checked the power before I connected the board !" and nobody to back him up. In my line of work, if some tech says "Can I get a witness ?" to you,
that's what he means. (he's not referring to a Southern Bible thumper)
“Bible thumper” describes the actions of a Christian fundamentalist, evangelist, or preacher who raps the bible with his knuckles to emphasize his sincerity while haranguing his audience, the congregation, or the crowd of curious bystanders.
