    • ‘Any of these factors could vary in a single instrument over the time period between successive calibrations.’
    • ‘But be aware that this is a highly complex device, and will require some careful calibration and setup.’
    • ‘They recommend quality control of laboratories, where calibrations are carried out.’
    • ‘The likely outcome of such an approach is that the models require major and separate calibration for every different circumstance.’

    • ‘Shortly before the helium runs out sometime toward the end of August or beginning of September, the team plans to perform an important series of instrument calibrations.’
    • ‘To allow frequent on-site calibrations, a new calibration procedure for erythemally weighing broadband radiometers that provides comparable measurements with the lowest possible effort is discussed in this article.’
    • ‘The next two sections provide a brief description of the two calibrations and are followed by a description of the experiment used to test calibration performance.’
    • ‘The oximeter device has been manufactured to automatically perform calibration when switched on.’
    • ‘She watched her instrument panel and saw as the minute calibrations to their trajectory were made.’
    • ‘Thermobarometers require thermodynamic calibration of the equilibrium constant for a particular reaction or set of reactions.’
    • ‘It's a rather crude and simple device, but still require calibration and care.’
    • ‘The instruments were swapped out for annual calibrations, so every year a different detector resided at each site.’
