Where do i put the thermometer probe at from my Ball Python?

Im not sure where i put it to read the temp for the ground.I have a heat pad and a heat lamp for him.I also have a thermometer that sticks on the wall of his tank.That reads 92 and the ground one reads 87.Im not sure if i have the probe in the right area or not.Where is the best place to put the probe thermometer at?|||Put it on the floor of the tank right above the heat pad. You want this temp to be about 85F. You can also move the probe to the spot under the basking bulb. This should also read about 85F. 92 is a bit too high. You can either move the light up higher or plug it into a dimmer switch to lower the brightness/heat. The other end of the tank should be cooler. Here is a great care site:
