The optic or non-drip measure is mounted beneath an inverted spirit bottle, so that a pre-defined volume of the bottle's contents drains into the measure. Lifting a lever on the side of the measure first closes off the measure from the bottle, then dispenses the measured liquid into the glass or mixing vessel held underneath.
For example, any instruction to read a measurement from an instrument will begin with "MEASure". Specific sub-commands within the hierarchy are nested with a colon ( : ) character. For example, the command to "Measure a DC voltage" would take the form MEASure:VOLTage:DC? , and the command to "Measure an AC current" would take the form MEASure ...
A measuring instrument is a device to measure a physical quantity. In the physical sciences , quality assurance , and engineering , measurement is the activity of obtaining and comparing physical quantities of real-world objects and events .
The field of spectroradiometry concerns itself with the measurement of absolute radiometric quantities in narrow wavelength intervals. [1] It is useful to sample the spectrum with narrow bandwidth and wavelength increments because many sources have line structures [2] Most often in spectroradiometry, spectral irradiance is the desired measurement.
Sample ShotCode linking to this article. ShotCode is a circular barcode created by High Energy Magic of Cambridge University. It uses a dartboard-like circle, with a bullseye in the centre and datacircles surrounding it. The technology reads databits from the datacircles by measuring the angle and distance from the bullseye for each point.

OMR tests form, with registration marks and drop-out colors, designed to be scanned by dedicated OMR device. Many OMR devices have a scanner that shines a light onto a form. The device then looks at the contrasting reflectivity of the light at certain positions on the form. It will detect the black marks because they reflect less light than the ...
