    Why does the LED bar graph stay lit during operation on Restek Security Sensors?
    • E
      Ebony LeeAug 10, 2025
      If the LED bar graph stays lit during operation of your Restek Security Sensors, it could be due to a couple of reasons: * The detector was re-zeroed before the unit was adequately purged. To fix this, allow sufficient time for the detector to purge, and then re-zero it. * The reference gas inlet is covered. Make sure there is no obstruction.
