/diy/ - Do It Yourself

What can cause a multimeter to read more resistance in a circuit than "actually present", going by the resistors I'm measuring?
I have a dpot driving a voltage step-up module, and when I measure the resistance on the dpot, it gives me like 50k, when it should be around 2-3k (and it is with the step-up module disconnected). There's also a 4.7k regular .5W resistor over the two pins of the dpot and it's not getting hot, I would've thought such a setup could never register more than 4.7k, only less.
