Engineering Words for EEE CSE Job Viva MCQ Question Answers
Capacity
The greatest load a weighing machine
is designed to weigh.
Sometimes marked on it as ‘Max’.
Calibration
Specific types of measurement
performed on measuring
instruments to establish the
relationship between the indicated values and known values of a measured
quantity.
NB: The term ‘calibration’ as
defined internationally does not include adjustment of the instrument.
Range
The least and greatest load for
which a machine is or can be used, and for which continuous mass values will be
displayed with the same resolution.
Repeatability
A measure of a weighing machine’s
ability to display the same result when repeated measurements are made under
the same weighing conditions.
Resolution
The mass value of the smallest scale
or digital interval displayed
by the weighing machine. Sometimes
marked on it as ‘d’.
Span
The mass value of the difference
between the greatest and least
load for which continuous mass
values will be displayed with the
same resolution.
Sensitivity
The number of divisions change in
reading per
unit mass.
Tare
Facility which enables the weighing
machine reading to be
adjusted to read zero with an object
on the load receptor.
Turning
point
The reading at the extremity of the
swing of the pointer, ie, where
it changes its direction of motion.
Not applicable to digital indicating
devices.
Uncertainty
The amount by which a true value may
differ from a measured
value, at a given confidence level.
