This one: Somewhat buried under multiple other modules. The battery is about where the oval is, and can only just be seen with a torch. The board has to come out. A splash of something.
Now I find some had got in through the vent holes, and dripped down both the case inside, and the mainframe. Very little, but maybe some got onto the CPU card.
So probably conductive. But first I prefer the alternative - just learn simple movement habits that control and dissipate static charges via paths other than through electronics. Always touching metal equipment frames first, or ground points on cards.
Keeping some skin touching metal frames at all times when working on gear. If picking up or putting down some static sensitive part, first palm-flat on the surface, to equalize potential desk surfaces are always slightly static conductive, just from normal dirt, sweat, etc contamination. So far as I know, this always worked - I never static blew a component. But with this spectrum analyzer, I want to be super cautious. Today I bought an anti-static mat and wrist strap from Jaycar.
The only type they had. This: As expected, the wrist strap lead end to end is 1 meg ohm. The black ground lead is direct wired from alligator clip to wrist strap sockets, and 1 meg to the mat pop-clip.
But what about the mat? It looks like just a sheet of vinyl, but with a pop-clip in one corner. This is made in China, why not be suspicious? Put 25V DC between the pad and clip. See if a multimeter Fluke 77 can see any differential voltage between either pads, and points on the sheet between.
A: not a sausage. No detectable conductivity. Expecting a garden variety multimeter to see anything is unreasonable. OK, so how to give it a fair test? Applies really really high voltage, high frequency excitation to whatever is near the tip.
Typically used to find leaks in vacuum glassware, because electrons will find even the tiniest passage. You look for where the glow goes. Dry concrete, wood, paper, etc. You can judge how conductive so-called insulators are, by how much the corona discharge is drawn to them. Here it is with concrete. The mat other end is sitting on the concrete. HV tester tip is about 1cm from the closer mat corner. For a comparison, a bit of wire with its other end point-touching the concrete. Even plain vinyl plastic.
All right, I need something that could be considered a fair competition. The setup: And running: Good heavens. It probably is just a bit of plain vinyl sheet.
