What do the settings on a multimeter mean?
Despite the fact the manual for your particular meter is missing, there are some fundamental concepts to using multimeters which you should familiarize yourself with.

I would recommend checking out some of the numerous online tutorials, such as this one from LadyAda, about multimeter usage. (Measuring resistance, specifically.)

Alternatively, you may want to acquire or borrow a meter with a manual and read up on it.

Ranges on meters denote the maximum value that the range supports. So 200k means you can measure from 0 to 200 k&Omega;. All of the readings shown while using that range should be in k&Omega;.

For example, if you instead set the range to 200 &Omega;, it would measure from 0 to 200 &Omega;, in which case the apple at 68k&Omega; would be out of range. The multimeter would display some sort of message to indicate out of range, but this differs by manufacturer/model.
