New member here. I just bought the GQ GMC 800 (for fun, mostly) and am trying it out. I have some familiarity with the general concepts involved but am by no means an expert.
One question: 1) In the Menu area there is a "Fast Estimate" setting called "Dynamic". If possible I would like to hear an explanation of how that setting works. (The other choices are 60 seconds, 30 seconds, 20 seconds, 15 seconds, etc.)
CPM = Counts per minute. 1 minute = 60 seconds. fast estimate settings: 60 seconds = uses a 60-second window to calculate the CPM. So it would take a whole minute to get an accurate reading. 30 seconds. uses a 30 second window to estimate CPM. so it takes last 30 second reading and multiply by 2. same as 20,15,etc. just different multiplier. Dynamic = detects if there is a significant change of incoming counts so that it uses a faster estimate time to get CPM. usually starts at 3 seconds. this window then slowly increases as long as it does not detect any significant change in counts to get a more accurate readings.
