Abstract
In a positioner, a driving signal IM is set to IMMIN (the minimum), a valve opening position A after the valve has then settled is stored, the driving signal IM is set to IMMAX (the maximum), a valve opening position B after the valve has then settled is stored, and the valve opening positions up until the opening of the valve arrives at the valve opening position B from the valve opening position A are stored together with the elapsed times as time series position information J, where, based on this stored time series position information J, the time for the opening of the valve to traverse between two prescribed valve opening positions that are established in the interval between the valve opening position A and the valve opening position B is calculated as a first response time Tup.
