I like the Data Logger/Viewer even better, now that I've figured out what the numbers mean (which I can't find elsewhere). Perhaps others and newbies like me will find the following helpful (and please correct any of my mis-perceptions).
In the audio/pulse-to-USB mode, with GC type GMC-200 selected:
* Saving files always wipes out your data logging session.
* Saved files are properly time-date stamped, but I see no way to set and the current time to the graph display. (No problem, really)
* The "Activity" is the count over the past 60 seconds.
* The estimated "uSv/h" is simply that Activity divided by 200. While dividing by 160 would be closer to the truth, and there appears to be no way to change this factor, I have no problem with that either.
* The "Average" is the CPMs averaged over the past 10 minutes (nice).
* To average over longer periods, you must divide the total count by the total elapsed time in minutes.
I can't make much sense out of the graph. Those blue bars seem to represent large rounded up/down jumps of levels in "peak" mode. In "total" mode it's totally confusing, since all the per minute values in the upper row keep squirming/changing.
Can anyone explain what's going on --and why there's no Y axis legend?
The blue bar only avaiable for the audio souce. The blue bar is displayed in the format of audio spectrum of frequncy.
The "Total" mode means avery second count received by software in past 60 secodns. It is mush easier to see the realtime data chaging than "Peak" mode.
