To provide a sensor-provided device, in which a customer engineer can immediately specify a sensor for which contamination is detected without viewing data, and the customer engineer does not need to come back many times for cleaning.

When sensor dust check is performed for a certain unit 6 of the sensor-provided device, the degree of contamination is determined for all sensors within the unit 6. When a sensor with contamination of a certain criterion or more is detected, a sub-unit 6D this sensor belongs to is displayed by lighting. According to this, sensors around the sensor for which contamination of the certain criterion or more is detected can be displayed as one group, and the customer engineer can clean the sensors within the displayed sub-unit.
