If your connections are wrong when working with the Stainless Steel Probe the read out results will not make sense. One possible mistake can be if you connect the signal wire (yellow wire) to the power side (red wire) of the resistor.
This connection configuration will lead to the following results using the testing sketch in post on 5/8/2011.
