Abstract
The noise calculation unit applies a statistical process for the measurement signal of the first number of data to calculate the noise value. The calculation threshold setting unit sets the calculation threshold based on the noise value. The period determination unit determines a period where a difference between the measurement signal and a moving average value calculated in a previous cycle exceeds the calculation threshold, to be the non-calculation period of the baseline. The moving average calculation unit is configured such that the measurement signal in a period excluding the non-calculation period is moving-averaged for each second number of data to calculate the moving average value. The first number of data and the second number of data are set independently.
