Freaky Amazing DMM?!

"HI-Z"

Spell checkers are not perfect. Nor are engineers.

No supposedly about it.

Much more importantly, the craftsperson knows the tools limitations and does not expect the tool to make up for any lack of skill on the craftsperson's part. And to bludgeon the point home, normally can make any tool(s) needed for task at hand.

Makes sense but do you concede that understanding the conditions matters more than the meter? What matters in wiring that is capacitatively or inductively coupled but not directly so, is that some kind of light load is placed on the line, and the voltage measured across that load. Only when that load needs to be a simple resistance can it be assumed that it is the meter's job to include it. In all other cases it can be assumed that the meter should tax the circuit as lightly as possible while analysing an external load chosen to fit the analysis needed. Which in turn directly implies that in the hands of someone who knows electricity, especially AC and frequency dependent behaviour, the high impedance meter is the way to go. Ideally with a plug-in load module or two, just as meters used to come with plug-in current shunts.

I don't test for live circuits with a DMM. I use test lamps or a low(er) impedance voltmeter. If you worked for me I would sack your arse if I caught you using a DMM to test for live.

Who said anything about it being *analogue* ?

Impedance is a property of the input of the meter not the display type.

I've used high and low impedance analogue meters and the same in digital form.

No, you carry the correct tools. You use a load to test for live/dead circuits, not a DMM. (I use test lamps with fuse protected leads). If you need to measure voltage, then you use a voltmeter...how hard is that to understand????

krw used his keyboard to write :

I didn't say you had to use an analog meter. I said that they do not have the same problem. An analog meter "IS A LOAD" a DMM is NOT.

No s*it... exactly my point. A voltmeter with a high impedance is not the tool to use to test for live circuits....

Sparky, carry crap tools? Ok, you don't need much and evidently=20 can't handle a good tool.

It is exactly the right term. It is a high impedance meter that has a shunt added to cripple it's input impedance.

If it was a .1% meter with the .5% feature added, yes, it was "crippled".

It does one thing and one thing only. The uncrippled meter will work in a wider variety of circumstances, though we are getting pretty far from the original point.

Jump into a discussion late, with both feet, often?

Read the thread.

Wow! I'm impressed! For a sparky, you're pretty sharp, there.

SO there *is* something wrong with a digital meter. I thought you=20 sparkys were just telling me that the display type didn't matter.

You couldn't afford me. I understand electricity.

It happens that krw formulated :

So you know nothing about working in the field...and you accuse me of not knowing how to use my tools?
