don't blame the meter, if you had a new digital meter, you would have
similar results, maybe even worse.
A volt meter is designed to measure voltage and is designed to be very
sensitve in the sense that it takes very little current. So even some
very small leakage CURRENT can register as a high voltage. Like when
you get a shock from a dry carpet, that is actually several thousand
volts, but the current is very low. so in the appliacne you are
measuring the AC line volage trhough the leakage path which is a very
weak high resistance path so very little current can flow but it is
enough to register on a volt meter. Actually the better the
voltmeter, the higher it will register. Voltmeters need more current
on the lower scale so when you switch to a lower scale it actually
drops the voltage more and you get a lower reading.
What you really need is an AC current meter to measure leakage. A
current of a few mA (thats milliamps = 1/1000 Amps) can give you a bad
shock. 100 mA = 0.1 Amps can easily kill you.
Most cheap meters unfortuntly cannot measure AC current. They can
measure DC current and DC or AC voltage. If you really want to
measure AC current, go to radio shack and buy a 1000 Ohm resistor.
Connect the resistor across your AC voltmeter leads. Now the AC
voltage reading will be about equal to the AC current. 3 volts will be
about 3 mA. Note that a ground fault interupter is set to trigger at
6 mA (I think I have that right, I'm sure someone will correct me if
Your TV antenna lead is probably grounded somewhere as it should be.
Your TV has a fair amount (but probably normal amount) of leakage that
you measure and feel. Your mixer has a smaller amount of leakage that
you can measure but not feel.
So now you can use your meter and if something measures like you mixer,
it is OK, If it measures like your TV, it is OK but has a higher
leakage that is in the range that you can feel. If something measures
much higher than you TV, I would become concerned.
( in any case I wouldn't grab onto your mixer or anything else electric
while standing in a puddle of water) :-)
