With a cage, I put the probe in the cage on the basking spot (or over the spot where the heat tape is on the bottom of the cage). You are trying to measure the actual temp of the spot where the animal will be. If you want the reptile to have an 85 degree basking spot, you set the temp on the unit to 85 degrees, the probe goes on the basking spot, and the heat source should run till the spot reaches 85 degrees. You'll need another thermometer to check the ambient temp of the cage (the cool side) to make sure you have a good gradient. For my rack, I put the probe behind the tubs next to the heat source (my rack is heated from the back). The difference in temperature in the space behind the tub and in the actual tub is only a couple of degrees, so I adjust my thermostat accordingly.
