Troubleshooting is incomplete. Contact technical support and provide settings, values, and the saved data file. There might be an issue with a neutron detector.
If a replacement neutron detector is available, consult with technical support to perform DET-HHD-THR-PAK-CM12 PackEye Neutron Detector Replacement.
The PackEye can continue to be used for operations. Use the FHT 1377 software to disable the defective neutron detector to prevent the solid yellow fail LED from illuminating.
