An error message appears during the calibration of the IdentiFINDER: "Unknown source present. Remove all sources and press AGAIN." What is causing this error?

Applies to: Radiation Identifinder (Gamma Spectroscopy) | Tickets Solved: 0 | Rank: 9.5

This error message on the IdentiFINDER indicates that the radiation background is too high to find the correct gamma line or that the noise level is not adjusted properly. This can be fixed by checking for the presence of radiation sources or leaving the area of increased background activity. Once the instrument is in a suitable environment, away from radiation sources and background activity, then the calibration can be attempted again. For further questions please contact technical support.
