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.

Take a measurement with nothing in the gauge. That reading is the zero-error.

The zero error depends on the user, and the wear on the metre rule. Given that smaller rulers have about 2mm of material before the zero mark, wear is unlikely to exceed that without being noticed. The reading error is +/- 1 mm.

The scale doesn't start at zero, so you need to compromise or you get a systematic error.

Difference between Proces Variable and set point is called " error (e) " . It is always kept at zero...

Positive zero error means, instead showing zero it shows some value more than zero. Hence positive. Suppose if it shows some reading say 0.03 units. then while correcting we have to subtract the above from the observed reading. So correction is adding negative error.

it will create a consistence difference in your readings as it is a systematic error.

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. Source: calculatored and written by Shaun Murphy

It is said to be positive when vernier scale zero is to the right of main scale reading and when vernier scale zero is to the left of main scale then it is said to be negative zero error.

An error in balancing is called an "error of measurement". The type of error that will be introduced if one fails to set the zero point of the balance before making the reading is a systematic error.

This micrometer has zero error.The zero marking on the thimble is below the datum line. So this micrometerhas a positive zero error.In this case we will take the reading on the thimble.Thimble reading = 0.03 mmSo the micrometer has a zero error of +0.03 mm.Whatever reading we take on this micrometer we would have to subtract +0.03 mmThe zero marking on the thimble is above the datum line. So this micrometerhas a negative zero error.In this case we will have to count the number of divisions on the thimble between the zero marking and the datum line.No. of divisions = 3Measurement of each division = 0.01mmSo the micrometer has a zero error of -0.03 mm.Whatever reading we take on this micrometer we would have to subtract -0.03 mm

Zero. In general, the difference between any number and itself is zero.

It is a probable an error of the balance or an improper use.

errors which come during compilation is known as compilation error. here we get syntax errors only not logical errors like division by zero. logical error occur during run time example:if you write a program for division with zero you will not get compilation error but during execution you will error

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.

The reading could be too high or too low.

· Zero Correction (Fz): If the zero reading in the hydrometer (in the control cylinder) is below the water meniscus, it is (+), if above it is (-), if at the meniscus it is zero.· Meniscus Correction (Fm): Difference between upper level of meniscus and water level of control cylinder.

If you are doing your job properly, you DO!

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 .

Coke zero is the same as sprite zero

the difference between two equal fractions is zero.

There is no such thing as pepsi zero

There is no difference in value between "equal" fractions: the difference is zero.
