I plotted the 10-hour data obtained by the data logger and compared with the trend.
Apparently the Ch2 (corresponds to BF H2) is noisy.
Other than that, I could not find the time the outputs became zeros during the measurement, while the trend data shows that PRM was operated in the ALIGNED state for a while.
I do not know why this happens. Do I misunderstand the time of the observation?
More investigation is required.
