it's interesting in that the capacitive buildup is bled off by the metallic mierals in h20. it makes sense in the old story about pure h2o being a bad conductor.
in the same vien, would conductors in close proximty of metallic substances also create this prob??
i have notice that these "induction pens"
( why not capactive pens?) ring easier in the presence of a heavy load.
in any event, one should practice certain safety measures when metering, or connecting a load.
unrelated, how many out there energize a load at arms length, once you have a firm grip, look away, then make contact? this is how i was taught.
