As a calculating method for the value Q, e.g. the attenuation time in which the value Q is lowered from a peak value down to a prescribed value is measured and found or the peak value itself is detected. The vacuum degree is judged on the basis of a fact that the larger the peak value is, the larger the Q value is.
