Posted - 10/12/2024 : 16:18:08 I only have the quick start guide and I cannot figure out how to read this or even really use it. I don't even know what CPM means.
CPM = Counts per minute. The amount of radiation activity the sensor detected. You can just compare it to the number on the card it came with to check for recommended readings.
