    keyword=Flammable gas sensors calibrated

    The Detector Gas System flammable gas sensors were calibrated yesterday. They were last calibrated in 2003 at the factory. I found them to be within 1% to 3% of the correct values, using the calibration gas cylinder. The operation of the receiver card for the sensor in the gas shed was verified visually at the Gas Master control box in the Counting Room. The operation of the receiver cards for the Left and Right Shield Huts were verified by looking at the EPICS archiver.
