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.
