DO NOT
Treat this like a hot stove or water; there’s no “let me just tap this…” like a shower; it’s instant.
Rely on insulated tools; may be easily mistaken for non-insulated, plus get in the, and only the, habit of using a stick
Let anybody near it, including pets
YOU NEED THE FOLLOWING:
Sign
Pocket
Wooden stick
Capacitor discharger
Safety glasses
If you already wear glasses, all set
Solder/flux
Diagnostic/measurement probing
Multimeters
Scopes – remove the ground clip (?)
Either way, if you are holding a probe, do not take your eyes off it!
There’s something about taking your eyes off of something that suddenly renders it “unsupervised” “wandering”
I’ve had a probe slip from its contact point many times, and always when I take my eyes off to just glance at a reading.
Use clips – get some halfway decent ones. The MIC ones/standard “gators” are cheap and imprecise (comes back again to “precision” for tools; tight tolerances; chinese gator jaws are horrible, plus the metal/plating is questionable).
