NOVELTY - The arrangement has an electrical conductive sheet (16) formed by thermal connection or thermally conductive adhesive between a sensing unit (5) and a specimen (7). An electrical test current path (22) is formed between the sensing unit and the specimen, where electric resistance between the specimen and the sensing unit is utilized as an indicator of quality of thermal connection between the sensing unit and the specimen. The sensing unit comprises a temperature sensor (1) and a circuit board (3). An electrical contact layer (9) is formed at a specimen facing side of the sensing unit.    USE - Arrangement for checking a thermal connection between a sensing unit and a specimen i.e. battery terminal (claimed), of a motor vehicle for preventing overheating and burning of a battery. Can also be used for a hybrid vehicle and an electric vehicle.    ADVANTAGE - The electric resistance between the specimen and the sensing unit is utilized as the indicator of quality of thermal connection between the sensing unit and the specimen, thus achieving reliable and precise temperature measurement in the arrangement, and hence ensuring reliable and safe battery operation in the motor vehicle. The electrical conductive sheet is formed by the thermal connection or the thermally conductive adhesive between the sensing unit and the specimen, thus ensuring safe and better surface contact of the arrangement. The application of the thermal connection and the thermally conductive adhesive permits easy replacement or positioning of the sensing unit on the specimen, and hence avoiding slipping of the sensing unit.    DETAILED DESCRIPTION - The temperature sensor is designed as a positive temperature coefficient (PTC) resistor element or a negative temperature coefficient (NTC) resistor element.
