On the 200k setting it reads 25.7, on the 2000k setting it reads 25. I reads nothing on the other settings.

You shouldn't keep using different settings on the meter. Use the lowest setting that's appropriate and take that reading. Increasing the resistance range makes the reading "less fine" and increases the voltage used to make the measurement.

I was just about to say the same thing.

When using non-autoranging DMMs you use the lowest setting that shows a value other than "OL" or "0.0".

On a 200K setting the max range is 200 000 ohms, so a reading of 25 on this setting is 25 000 ohms. Using a a range setting of 200, and reading 25, the result would be 25 ohms.
