Common sense without underlying knowledge makes one his own fool.
For example, what happens when all outputs from a powered power supply
are shorted together? Naive know that a power supply is damaged. But
even 30 years ago, a short circuit must not cause power supply
damage. Short all the outputs from a power supply to create no damage
and no human threat. Why? Because anything dangerous is elsewhere.
Why does Mark N use profanity? A symptom of those who somehow know
before learning facts. Mark N actually thinks a meter will cause
damage or harm humans? Its instructions were too complex? Even
cavemen had no problem reading. Simple. Set meter dial to range (ie
20 VDC). Touch probes to wires. Read numbers. Even Geico is more
complex.
How can one damage a computer? Disconnect things - also called
shotgunning. Disconnect nothing inside a computer when using a
meter. Just another reason why a meter is a preferred solution. No
one needs profanity to know that.
Those who promote fear also would know an Ipod is too complex.
After all, a 3.5 digit multimeter is only sold in K-mart, Lowes, and
Wal-mart because - as Mark N implies - one must be a genius to use
one. Those who first learn before posting know why that meter is even
sold in Radio Shack and Tru-value hardware stores. It is a tool as
'dangerous' as a screwdriver. And sometimes sold on sale for $10.
What is wrong with friesian's computer? Two minutes with a meter
provides useful numbers to learn and to post for useful replies. Back
in cavemen days, we kids used VTVMs. Even VTVMs were safe and simpler
than an Ipod. We cavemen did not fall for myths, fear, and profanity
promoted by Mark N. No mocking. No insults. Just reality.
Apparently Mark N warns us to not buy a too complex and too dangerous
Ipod. Others instead learn from reality; gain experience and
knowledge; don't fear.
