  George TylerAug 9, 2025
  If the display varies too much on your BERTHOLD TECHNOLOGIES Switch, it could be due to several reasons. The time constant might be too small, in which case you should increase it. Another cause could be a count rate that is too low, so you should check the source age and irradiation level and replace the detector. Finally, detector stabilization may be faulty, so consider replacing the detector.

  If the count rate is too low on your BERTHOLD TECHNOLOGIES Switch, first check if the shielding is not open or not properly open and lock the shutter in the OPEN position. Also, verify that the useful radiation is correctly aligned towards the detector and optimize the alignment. Container installations in the radiation path may be the cause, so offset the irradiation level. Additionally, remove any wall deposits in the container. Finally, the source may have reached the end of its service life, so replace the source.
