A first control value related to registered temperature time profile is determined for several points in time and the determined control value is compared to limit value. A second control value establishing a mathematical connection between potentials is determined for points in time, when first control value is equal to or greater than first limit value. The determined second control value is compared to second limit value. A signal is generated, when the determined second control value is equal to or less than the second limit value. An independent claim is included for probe for use in measuring medium. |
