A parameter may be measured and recorded on an instantaneous basis (i.e., the value that occurs at any time) and the operating limit specified as the time-weighted average during all runs of the compliance test. NR 666.103(3)(d)4.b.b. 1) The limit for a parameter may be established and continuously monitored on an hourly rolling average basis defined as follows: a) A continuous monitor is one which continuously samples the regulated parameter without interruption, and evaluates the detector response at least once each 15 seconds, and computes and records the average value at least every 60 seconds.
