Abstract

PURPOSE: To continue the automatic operation with the use of elements left untroubled, while being free from being unabled to accomplish the measurement, by dividing heat-sensitive elements into plural groups so that the measurement may be continued by isolating the troubled elements.
CONSTITUTION: Heat-sensitive elements T1 to T6 are divided into odd and even groups and are equipped with: trouble detecting circuits 61 to 66; circuits 601 and 602 which are made responsive to the troubles of one or more elements of the odd or even groups; and responsive switches 603 and 604 for turning on and off the elements. If, now, the element T4 is troubled, the detecting circuit 64 is operated to feed its signals to the circuit 602 so that the switch 604 is turned off to isolate all the circuits of the heat sensitive elements of the even group. Even if the elements are partially troubled, therefore, the measurement is not made incapable but can be continued under a slightly degraded accuracy, thus making it possible to continue the automatic operation.
