Particulate measurement apparatus and particulate measurement system

In a particulate measurement apparatus (300) of a particulate measurement system (10), a control section (600) provisionally determines in an anomaly determination process at S130 that a corona core wire (202) is in a wire-breakage anomaly state; namely, that the corona core wire (202) is broken, wh...

Zusammenfassung:	In a particulate measurement apparatus (300) of a particulate measurement system (10), a control section (600) provisionally determines in an anomaly determination process at S130 that a corona core wire (202) is in a wire-breakage anomaly state; namely, that the corona core wire (202) is broken, when a corona low-side current C1 is equal to or smaller than a current determination value C1min, and increments a wire-breakage anomaly counter CNB at S140. The control section (600) determines that the corona core wire (202) is in the wire-breakage anomaly state at S170 when 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 S160 is "Yes".
