It's 5 meters in length, and .5mm in diameter. What is the best way to go about removing the insulation on the ends of the wire without damaging it? The circuit itself runs by the way, so there are no problems with the jumper cables. Also, the instruction booklet lists it as able to record up to 60MΩ.

For my science fair project this year I'm measuring the effect of temperature of a wire on resistance. The circuit I made is working, but when I try to use the ohm meter it doesn't display the resistance. Does anyone know what I could do? Images: http://imgur.com/a/nV7hM
