    To accurately reflect the effects on vision, the measurement must be made over a long enough time (10 minutes or 2 hours). That said, flicker can vary considerably in a short time, since it depends on connections and disconnections to the network. The CA 8345 therefore measures: „ instantaneous flicker Pinst, The value displayed is max(Pinst) on a 150/180-cycle aggregation.
