I'm testing a new DMM I purchased, AM-240 by Amprobe. It claims *over*
100Mohm impedance in 400.0mV mode.
Nothing new there, many DMM's have selectable "high impedance" or "HI-Z"
modes on the mV range. e.g. the Fluke 87.
I've looked at the specs of ~ 30 DMM's today, include a lot of
fluke's, and never seen anything near 14Gohms impedance. Keithley has
an electrometer that's probably higher. Most DMM's are around 10Mohms
(not gigaohms) input impedance. Don't you think 14 gigaohms is a bit
high?
PL
The evil thing about Voltmeters with very high impedance is they will
read induced voltages that analog meters wouldn't.
It makes a voltmeter useless for checking for live circuits in a
crowded panel.
A craftsman never blames tools for his failures. Hackers, on the
other hand...

fluke's, and never seen anything near 14Gohms impedance. Keithley has
an electrometer that's probably higher. Most DMM's are around 10Mohms
(not gigaohms) input impedance. Don't you think 14 gigaohms is a bit
high?

The evil thing about Voltmeters with very high impedance is they will
read induced voltages that analog meters wouldn't.
It makes a voltmeter useless for checking for live circuits in a
crowded panel.
A craftsman never blames tools for his failures. Hackers, on the
other hand...
If you work with electricity you had better know the limitations of
your tools or you will find them...the hard way.
That is certainly true (though perhaps your heirs are the ones who
will find you), but doesn't modify my statement. In this case, the
tool *can* be used as long as the one using it knows what he's
doing.
Ok....everything seems to pass right over your head....
I pointed out a limitation of a DMM and you seem to be inferring that I
am somehow a hack who blames his tools...
BTW> I am not a "craftsman" I am an electrcian..
You don't do what I do for as many years as I have without knowing what
the fuck you are doing.
What's wrong with using a hi Z voltmeter in a live panel? I do it more
often than I really care for, and never have a problem.
There isn't anything wrong with it. Analog meters are dead. High
impedance digital meters are only a problem if there is a loose nut
inside the panel, holding the leads.
Then I suppose Fluke and others make all those purpose designed Low-Z
electrical meters for loose nuts then?
...and electricians who know nothing about electricity, perhaps.
But at least smart enough to chose the right tool for the job.
Totally useless in areas of high RF.For anyone who knows anything about electricity or wants a tool that
has more than one use, the high impedance meter is a better choice.

I would agree. Take two meters. One is 1Kohms. The other is 1Gohms. If
the load is low impedance, say 100 ohms, then there's an appreciable
error with the low impedance meter-- simple ohms law. While the error
associate with the high impedance meter is unmeasurable.
People are probably confusing the fact that a high impedance meter
while unconnected to anything will pick up signals, for obvious
reasons.

Sorry, I didn't pay much attention who I was replying to. I'm not
taking sides, but I am saying that high impedance meters are better.
