Ohmmeter Setting Question?

Question

On my ohmmeter this is a section with the following values. 2000k, 200k 20k, 2000 with a horseshoe sign next to it, and 200. I used the one with the 200. I want to know what unit this is and how should i write it. I know the other ones but the 200 on its own i dont know what it stands for

Thanks for your help

Answer 1

the horseshoe is the greek letter omega and it is the unit for resistance.
200 = 200 ohms
2000= 2000 ohms
2000k = 2000000 ohms
the k means to take the number an multiply by 1000
if you see an M that means to take that number and multiply by 1 million.

Answer 2

If it's mechanical meter, the number is the resistance in ohms that would give the meter a full-scale deflection. You'll generally get the most accurate reading near the center of the scale, so if your resistance is about 10,000 ohms, use the 20K scale.

A digital meter isn't likely to have settings like this, but if it does, then again choose the one where the resistance is near the center of the range.

Note that in this context, the 'K' scale factor is the metric one of 1000 rather than the computer-related one of 1024 (2 to the 10th power).
