High Voltage measurement
Let's handle High Voltage
You sometimes may get the impression that I don't take high voltage lethality serious. Let me seriously assure that I don't screw around when it comes to lethal high voltages. It is deadly stuff and I don't "play" with it or demonstrate bravery to guest.

You will see a few references to high voltage measurements, such as AC plate transformer secondary volts and rectified/filtered B+ DC voltages. How do I do it? I do it the professional and safe way. First I don't demonstrate this to anyone, no distractions - my full attention and concentration.

Master switch off, I clean off the bench. Nothing but the amplifier or device and the actual equipment to be utilized. Usually just the 10 mega ohm input digital volt meter, Fluke 40 KV high voltage probe properly plugged into the meter and ground clip attached to equipment chassis ground. I then run through, in my mind, exactly where I am going to measure voltage with the probe and make a note on a pad off to my right. I note whether the voltage is AC or DC and what voltage or range to expect. After I am clear and focused on what I am about to do, I set the meter for voltage type, slip the fresh thick leather welding glove on to my right hand and with left hand in my pocket, I pick up the high voltage probe and carefully touch the probe tip to the connector, terminal or spot for measurement and read the voltage in decimal kilovolts on the meter.

I lay the probe over by the note pad, remove the glove and note the voltage. Then I repeat for next measurement. After last measurement, I turn the master switch off an go do something else while voltage and energy bleeds off.

Oh yea, a while back I got a grade five surprise. The scale, important upper numbers  - -  

5 getting the shock of your life and scared, almost to death, overcome with self stupidity .
6 as above and being holed in several places.
7 all of the above and knocked on your ass.
8 all of the above and you couldn't breathe and thought you were dead.
9 all of the above and hospitalized, people trying to keep you alive
10 - - - - - - - - - - - SK.

HAM总有SK（Silent Key）的一天，但我绝对不希望因为自己愚蠢的过失提前参拜马可尼老人家……
