Hi, I got the Geiger counter model series 900 mini monitor and when I do the battery check it works all fine but when I turn it on so I can do radiation readings then the needle doesn’t move at all or make a speaker sound would you be able to resolve me the problem or tell me what it can be so I can get it fixed?
