A tour of Agilent Australia’s new VOSCAL (Volume On-Site Calibration) portable NATA accredited calibration lab in a customised expandable shipping container, with Metrologist Peter Daly The gear alone inside is worth a cool $3M. Photos HERE Forum Topic HERE
A look at one of the original HP 5061A Cesium Beam atomic clock frequency standards used in the “flying clocks” experiment in the 1960′s, that showed (not definitely at the time) that time dilation as part of Einstein’s relatively theory was correct. The effect was not confirmed until a more precise run in 1971, again with the same clocks. Forum Topic HERE
Les Thomaidis shows and explains the calibration rack at the Agilent Melbourne Standards Lab that is used to “calibrate the calibrators”. This is where other calibration labs send their multimeter and oscilloscope calibrators to get calibrated. Forum Topic HERE
