Is zero error necessary?
that means having no error.we will know that byerror so we need it.
Why is the use of zero error is necessary in in a measuring instruments?
haahahahh
Why don't you add or subtract the zero error from the reading when you measure depth from vernier caliper?
If you are doing your job properly, you DO!
How do you find zero error of screw gauge?
Take a measurement with nothing in the gauge. That reading is the zero-error.
What is Zeroing Error?
Suppose say you have plastic rule new one. There you will be having zero marking. When you have to measure the length of a rod then you would keep zero marking at one end of the rod and the marking where the other extreme of the rod is taken to be length of the rod. say it is at 4 cm. So 4cm is the length. And suppose the ruler is an old one whose edge got damaged. Now you don't have zero marking so visible there. So you have keep the end of the rod at say 1 cm marking. Now the error that we commit is known as zero error. Here the error is positive. ie +1 cm. So as the other end of the rod is at 5cm marking then the correct length is got by applying zero correction. As zero error is +1 cm, then zero correction would be -1 cm So the correct length 5-1 ie 4 cm. Same way in case of vernier, if zero of vernier is at left side of zero of main scale, then the zero error is negative. If zero of vernier is right side of zero of main scale then error is +ve as we have seen in the earlier old ruler case. Same way in case of screw gauge as the head scale zero is above pitch line then error is negative and as head scale zero is below pitch line then zero error is positive.
Why is zero error not considered in spherometer?
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.
What is common error associated with tape measure?
Zero error and parallax error
What is zero error in vernier caliper?
The zero error of a measuring instrument is the measure that it shows when it should actually be showing zero.
Why is use of zero error necessary in a measuring instrument?
Zero error is necessary for measuring instruments for measuring accurate results because it helps to check that the instrument which we are using is whether correct or wrong
Why is the use of zero-error necessary in a measuring instrument?
The zero error helps in correcting the misreading you get from any instrument. It helps in maintaining the sensitivity of the instruments.

What is a zero error?
if the zero line of vernier scale is not conciding with main scale the zero error exists.Knowing the zero error necessary correction can be made to find correct measurement..Such a correction is called zero correction
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 .
Why don't you add or subtract the zero error from the reading when you measure depth from vernier caliper?

Describe the conditions necessary for a measure of variation to have the value zero?
The measurements for all members of the sample are the same.
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.
