Zero error is defined as the condition where a measuring instrument registers a reading when there should not be any reading. In case of Vernier calipers it occurs when a zero on main scale does not coincide with a zero on Vernier scale.

Zero error occurs when a measuring instrument does not read zero when the true value is zero. To calculate zero error, you take a measurement of a standard reference (ideally zero) and note the difference between this reading and the expected value of zero. Zero correction is then determined by subtracting the zero error from your subsequent measurements to adjust them to the true value. For example, if the zero error is +2 units, you would subtract 2 from all future readings to correct them.
Take a measurement with nothing in the gauge. That reading is the zero-error.
Zero error of an instrument refers to a discrepancy that occurs when the instrument does not read zero when it should. This can result from miscalibration or mechanical faults, leading to inaccurate measurements. For example, if a scale shows a reading of 2 grams when nothing is placed on it, it has a zero error of +2 grams. Correcting for zero error is essential to ensure accurate readings during measurements.
To remove zero error from a micrometer, first ensure that the micrometer is closed completely without any object between the measuring surfaces. Then, check the reading on the scale; if it does not read zero, note the error value. Adjust the micrometer’s zero setting, if it has one, or account for the error in future measurements by subtracting the zero error from your readings. Finally, recalibrate the device regularly to maintain accuracy.
the correction which is made to get correct measurement after zero error
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 .
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.
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 .
Some types of errors in physics include systematic errors, which result from flaws in experimental setup or measurement instruments; random errors, which occur due to fluctuations in experimental conditions or human limitations; and instrumental errors, which arise from inaccuracies or limitations in measurement devices.
The zero error of a measuring instrument is the measure that it shows when it should actually be showing zero.
What is the formula for percent fractional error? (Physics)
Work is zero in physics when there is no displacement of an object, meaning that no force is applied to move the object over a distance.
zerro error in a spring balance affects the accuracy in the weight. To find zero error in spring balance, you have to first find the least count of the spring balance and then suspend it freely, if the outcome is +1, the zero error is +1 and if it is -1 ,the zero error is -1.
Take a measurement with nothing in the gauge. That reading is the zero-error.
The answer is in your own question. A divide by zero error is a divide or mod by zero type of error. In MSVC++ it has the error code C2124. Ultimately it is a fatal error and will either produce a compile time error or throw an unhandled exception at runtime.
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
