AD590MF Temp Sense Anamoly

I have a AD590MF Temp Sensor and the resistance between the -ve and the +ve leads fluctuate from 2Mohms to 12.0 Mohms. Is this normal. Somehow this Temp Sensor quit working on one of the systems I work on and do not seem to find the cause. The only thing I noticed was that the Temp Sensor was not bonder the surface in the right orientation. Typically we bond to the non metallic surface but in this case I found the metallic surface bonded to the area where I needed the Temperature readout from. Could this have somehow damaged the Temp Sensor?
