I thought that's what you were looking for.  By turning the wiper all the
way to the connected end, you can measure the end to end resistance without
the connected circuit interfering.

If you know it's a 5K Ohm pot, then what's the problem?  Those should be
readily available from many places.  The exact mechanical fit would be more
the issue.

Why do you think you need to profile the values?  You said it was a speed
control for a blender, if I remember right.  Are you thinking this might be
a audio taper pot of something?  If so, you're overthinking this.  Audio
taper pots are for volume controls, and are getting scarce nowadays anyway.
It will be a linear taper pot, probably the cheapest crappiest pot the
blender company could stick in there to not fail before the warranty
expires.  Besides, isn't this just a uncalibrated speed control?  Does it
really matter if the speed is a little bunched to one end?  And if it is, a
fixed resistor accross or in series should be able to help.
