TESTING METHOD FOR NON-INVASIVE TEMPERATURE MEASURING INSTRUMENTS

A method for testing a temperature measuring instrument (1), wherein said instrument (1) comprises at least one sensor (2a-2c) that changes its electrical resistance R, and/or an electrical voltage U that it produces, in response to being exposed to a change in temperature T, and wherein the instrum...

Summary:A method for testing a temperature measuring instrument (1), wherein said instrument (1) comprises at least one sensor (2a-2c) that changes its electrical resistance R, and/or an electrical voltage U that it produces, in response to being exposed to a change in temperature T, and wherein the instrument (1) is configured to be coupled to an object of interest (3), the method comprising:* changing (110) the temperature T of at least one sensor (2a-2c) by an amount that is detectable given the measurement resolution dT of the at least one sensor (2a-2c), by driving an electrical manipulation current IM through this sensor (2a-2c);* obtaining (120) one or measurement values (4) from at least one sensor (2a-2c); and* evaluating (130) a state (5a) of the measuring instrument (1), a state (5b) of one or more of its sensors (2a-2c), and/or a state (5c) of a coupling to an object of interest (3), from the one or more measurement values (4).
