If you're seeing a reading of 100 on the X10K scale that indicates that the pot is measuring 1 million ohms or 1 Megaohm which is twice the correct value and shows that the pot is faulty. 100 x 10,000 = 1,000,000.

I spoke of an auto-ranging meter. An auto test meter may be something for working on automobiles.

You can see my own auto-ranging meter in this thread:-

Note that it has a single resistance range denoted by the Ω symbol.
