No, you have not any knowledge about spherometer. In spherometer also, similar to other measuring instruments zero error should be considered every time; in order to achieve accurate value.

Zero error is not considered in the spherometer because the reading is measured by obtaining the difference between initial reading and final reading
So, it is already accurate

How do you find zero error in spherometer?
To find the zero error in a spherometer, place the instrument on a flat surface and check if all the legs touch the surface simultaneously. If there is a discrepancy, adjust the screw until all legs make contact at the same time. This position with all legs touching is considered the zero error.
What do you mean by backlash error of spherometer?
when the three outer legs tilt or doesnt stand still,it's called backlash error in spherometer...
Why spherometer is called spherometer?
The reason a spherometer is called a spherometer is because it measures the radius of a sphere.
How do you avoid backlash error in spherometer?
To avoid backlash error in a spherometer, always approach the surface being measured with the same direction of rotation when adjusting the measuring screw. Additionally, make sure to account for any play or slack in the screw mechanism before taking your measurement. Regularly calibrate and maintain the spherometer to ensure accuracy and minimize the risk of backlash errors.
Why spherometer is so called?
The reason a spherometer is called a spherometer is because it measures the radius of a sphere.
Who invented spherometer?
The spherometer was invented by William Gascoigne in the 17th century. It is a precision instrument used to measure the curvature of spherical surfaces.
What is the unit of measurement in spherometer?
A spherometer is an instrument for the precise measurement of the radius of a sphere. The spherometer directly measures a sagittal. Since the spherometer is essentially a type of micrometer, it measures very small things like millimeters.
How do you find the zero error and zero correction in sgrew gauge?
we can find the zero error by closing the jaw of screw guage if the zero of main scale(MS) is concide with the zero of circular scale (CS) there is no zero error and if they are not concide there is a zero error in screw guage .
Define the term zero error of vernier calliper?
The zero error of vernier calliper is defined as :-The zero error is equal to the distance between the zero of the main scale and the zero of the vernier scale.
What is Positive zero error?
if the zero of vernier scale lies on the right side of the zero of the main scale , then error is known as a positive error .
Why spherometer has 3 legs?
because to determine the radius of curvatureof a given spherica surface by spherometer
What is pitch of spherometer?
The distance moved my the screw in one complete rotation in the circular scale is called the pith of spherometer.
