Hello,
I have a GMC-300E and I try to get the cumulative dose in Sv from total count, not the average dose per hour from CPM.
It seems that :
0.5 * 10**-6 * CMP = Sv/h
So I expect that : is it right ?
0.5 * 10**-6 / 60 * TotalCount = Sv
An other question : how does the inner CPM counter compute ?
Is there a small array with 60 index for each second per minute, and CPM value is : NowTotalCount - PreviousTotalCount60SecondsAgo.
Many thanks !
F. happy with this little Geiger-Muller counter. |

And I forget to divide by 100 :
The coefficient must go from 20CPM to 0.10microSv/h
not to a hight 10microSv/h.
So I replace 10**-6 by 10**-8 in the previous formula... |
