Basic multimeter question

[Guido]

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.

Neither. Assuming you mean it reads '67.0', then the resistance is
67k, i.e 67,000 - or, in your notation, 67.000

Neither. Assuming you mean it reads '67.0', then the resistance is
67k, i.e 67,000 - or, in your notation, 67.000
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?

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.

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

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

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

Have Fun!
