After playing around with it for 2 weeks now, I am understanding the fuctions and features, but still have 2 things I cant explain myself: [b]The "Fast Estimate Time“ feature [/b] I unterstand that it defines the time base on which the CPM or uSv/h are calculated. This works well and is plausible for 20s, 30s and 60s But as soon as I choose 15s or below the values jump from 50CPM to 300CPM like crazy, mostly way over 100 CPM in my house, where I usually get 30-45 CPM in average with the 60s mode. Is this a software problem? [b]The Dosimeter Function[/b] When I switch to "Text Mode“, I can get the „"Total uSv“... is that the dosimeter? Because if yes, it also counts backwards... but a dosimeter should always count forwards I assume.... Anybody got any clues? Thanks a lot!
