  • Hi

    I have the old version i think code 7-18-11. its been working fine for about 1 year logging away but today its just went out of control started reading 80 CPM (I hope out of control anyway). I reset it did the standard turn it off and on and now its reading nothing. Is this a common symptom when it fails to give such large CPM counts ?

    Thanks,

  • Quick Question as I could not find a guide. When connected to the Geiger Counter I get random bits 0s and 1s at random time intervals. My understanding thus far is that the 0 & 1’s represent either gamma ray, alpha, or beta particles hitting the tube. Why is there a 0 and a 1 ? Does the 0 mean its one type of particle ? Thanks,
