Abstract: A load drive apparatus (1) includes a pulse drive circuit (51) which applies a pulse voltage PS to a resistive load (4); current detection means (S14) for detecting the current flowing to the resistive load (4) through the pulse drive circuit (51); level detection means (S1, S7) for determining whether an output terminal voltage VD of the pulse drive circuit (51) is a high potential level or a low potential level; anomaly detection means (S8, S9, S18) for detecting a wire breakage anomaly, a short-to-power anomaly, and a short-to-ground anomaly based on the level of the output terminal voltage VD detected by the level detection means (S1, S7) and the current detected by the current detection means (S14), when the pulse drive circuit 51 is turned on and off.

Abstract: 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”.

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.

Abstract: A measurement apparatus includes a plurality of modules and a main unit for collecting measurement data output from the modules. The housing of the main unit can be carried by a user of the measurement apparatus, and the plurality of modules are removably accommodated in the housing. A CAN I/F circuit of the main unit collects the measurement data output from the module accommodated in the housing. A main CPU of the main unit outputs the collected measurement data to, for example, a personal computer connected to the main unit. An internal memory and a USB memory connected to a USB memory module store the collected measurement data.
