Abstract
A particulate measurement apparatus comprises a control section, which provisionally determines in an anomaly determination process that a corona core wire is in a short anomaly state when a linear voltage is equal to or lower than a particular voltage value and increments a sensor anomaly counter CNS or a chassis anomaly counter. The control section determines that the corona core wire is in a short anomaly state when the count value of one of the anomaly counters is equal to or greater than a determination threshold.
