How to use Read-off in a sentence
The angle through which the arm was moved, or, in the latter case, the angle between the two arms, was read off upon a finely graduated arc. With such means no very high accuracy was possible.
The total number of revolutions is read off by a scale attached to the side of the box, but not seen in the figure.
The same firm is also constructing a micrometer in which the readings of the head are printed on a band of paper instead of being read off at the time of observation.
The image of the star is set updn the intersections of the lines of the central cross, and the positions of the reseau-lines are read off by estimation to - of a division on the glass scale.
Its fundamental principle is that, by a combination of glass scales with a micrometer screw, " the chief part of the distance to be measured is read off on the scale; the fractional part of the scalespace is not estimated but measured by the screw."Advertisement
The distortion of the spring determines the actual force which the wind is exerting on the plate, and this is either read off on a suitable gauge, or leaves a record in the ordinary way by means of a pen writing on a sheet of paper moved by clockwork.
Lines representing efficiency ratios of o 6, 0.5 and 0.4 are plotted on the diagram, so that the efficiency ratios corresponding to the various experiments plotted may be readily read off.
It ascends the tube, the substance is rapidly volatilized, and the mercury column is depressed; this depression is read off.
To determine the density of any liquid it is only necessary to suspend the plummet in the liquid, and to bring the beam to its normal position by means of the riders; the relative density is read off directly from the riders.
Bessel's practice was to unclamp in declination, lower and read off the head, and then restore the telescope to its former declination reading, the clockwork meanwhile following the stars in right ascension.Advertisement
Apparatus is added to some dynamometers by means of which a curve showing the variations of P on a distance base is drawn automatically, the area of the diagram representing the work done; with others, integrating apparatus is combined, from which the work done during a given interval may be read off directly.
Poncelet, from which the work done during a given displacement could be read off directly.
A Morin disk and roller integrator is connected with the apparatus, so that the work done during a journey may be read off.
These theorems may prove useful in preliminary calculations where the pressure-curve is nearly straight; but, in the absence of any observable law, the area of the pressure-curve must be read off by a planimeter, or calculated by Simpson's rule, as an indicator diagram.
If we now attach to the polar axis a graduated circle D D, called the" hour circle,"of which the microscope or vernier R reads o h when the declination axis is horizontal, we can obviously read off the hour angle from the meridian of any star to which the telescope may be directed at the instant of observation.Advertisement
The observer at the eye-end can also read off the hour and declination circles and communicate quick or slow motions, to the telescope both in right ascension and declination by conveniently Pulkovo, placed handles.
When the load exceeds 2 lb one or more 2-lb weights are placed in the weights-pan, and the value of the portion of the goods corresponding to these 2-lb weights is computed, at the rate per lb, in the ordinary manner; and the value of the balance of the weight of the goods is read off the chart, and the two are added together.
If the micrometer is then moved till another graduation corresponds to the other edge of the image the size of the image can be read off.
The angular or numerical aperture can then be read off.
A precise measurement of the loading is then read off the steelyard.Advertisement
Since the calls are increasing, we now have a 'script' we read off of about what we are doing for the launch.
Breitling dials are "designed for optimal read-off at a glance, like an instrument panel."
