Basic multimeter question

Hi,

I'm new here and just now I got myself confused.... and am ashamed off it!! ;-)

When I measure the resistance of a resistor, and have my multimeter in

200k position, and the resistance measures 67 ....

Is the resistance 670.000 or 6.700.000

???

Tnx. :)

so to make it more clear to me:

when 67 is displayed in the 200k setting would mean 670k since we're working with hundreds in this setting versus 67 in the 20k setting being displayed as 67k since we're working with tens in this setting?

If that is so... why did they use 20, 200, 200, 20k, 200k, 2000k versus 10, 100, 1000, etc. Confusing (needs getting used to) Industry standard or free choice from manufacturer?

ah, ok, that answers my previous question if it is an industry standard. the 200k part reverse to the maximum reading in that setting.

Tnx

The 200k position means it reads 200k at full scale. full scale is when it's showing 199.0, so 67 means 67k. On the 2k scale, it would read 1.99 at full scale, and 0.67 would mean .67k=670 ohms, etc.

probably because if it was 10..., you'd have a 0-10v voltage range, which wouldn't cover a lot of common circuits. So people would have to switch to

0-100v, which would be too high so you lose accuracy. Plus it's easy to add a single extra '1' at the left hand side of the display, and leave room for the - sign. Most likely a load of ad hoc influences like this rather than any thing definite.

On Friday 10 September 2004 12:13 pm, Guido did deign to grace us with the following:

Well, if 200 on your display means 200K, then 67 on the display means

67K.

It's probably really 19.999, 199.99, 1999.99, and so on, which they round up for marketing purposes.

Have Fun! Rich
