Why do some materials cause my meter to jump around?

    I have a manual ranging meter and it works great. I was wondering why on certain materials, metal or otherwise, when I measure resistance the meter tends to jump to crazy values, occasionally settling on the suspected resistance for a short bit, and then jumping all over the place again. On store-bought resistors or conductors it never has any problem settling on the value.

    What's going on here? :confused:

    Thanks

    Painted, dirty, or corroded connection points on the non "store-bought" materials?

    It didn't seem painted. What I was measuring when I thought of this was the actual conductor terminal of a lamp switch.
