Abstract
In a particulate measurement apparatus () of a particulate measurement system (), a control section () provisionally determines in an anomaly determination process at Sthat a corona core wire () is in a wire-breakage anomaly state; namely, that the corona core wire () is broken, when a corona low-side current Cis equal to or smaller than a current determination value Cand increments a wire-breakage anomaly counter CNB at SThe control section () determines that the corona core wire () is in the wire-breakage anomaly state at Swhen the count value of the wire-breakage anomaly counter CNB is equal to or greater than a wire-breakage determination threshold Cth; namely, that the result of the determination at Sis 'Yes'.
