摘要： A particulate matter detector of the present invention has an electrode portion, a signal measuring portion, and a calculation portion and further has a measurement signal memory portion for memorizing the values of the measurement signal measured by the signal measuring portion, a signal judgement portion for judging the necessity of correction by comparing a calculated amount of change with a value of a background signal noise after calculating an amount of change between values of the consecutive measurement signals of 10 or less samples memorized by the measurement signal memory portion, and a correction portion for correcting the value of the measurement signal, if the calculated amount of the change shows a decrease of at least twice the value of the background signal noise, by adding the decrease value to the value of the measurement signal where the decrease is confirmed.
摘要翻译：本发明的颗粒物检测器具有电极部分，信号测量部分和计算部分，并且还具有用于存储由信号测量部分测量的测量信号的值的测量信号存储部分，用于通过在计算由测量信号存储部分存储的10个或更少个样本的连续测量信号的值的值之间的变化量之后，将计算出的变化量与背景信号噪声的值进行比较来判断校正的必要性，以及校正部分为了校正测量信号的值，如果所计算的变化量显示出比背景信号噪声的值的至少两倍的减小，则通过将减小值与确定了减小的测量信号的值相加。
