Note that the larger the data value is, the slower the response time. •In case of setting "17", it indicates the setting of 16 moving average calculation disregarding the voltage fluctuation equivalent to 0.1 Hz. Though the frequency becomes less likely to fluctuate, the resolution for analog input decreases. This setting is not suitable for equipment that requires rapid response.
