This is the measurement recorded when, in fact, it should be 0. It is the measurement when there is nothing to measure but the reading is not exactly 0 because the calibration has gone off.

How you remove positive zero error?

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.


What does negative zero error mean?

There can't be a negative zero. zero is neither negative nor positive.


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.


What is zero negative property?

Zero is not negative. It is not positive either.Zero is not negative. It is not positive either.Zero is not negative. It is not positive either.Zero is not negative. It is not positive either.


How do you find zero error of screw gauge?

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

How do you take readings from a micrometer screw gauge?

The first step is to find the zero error and hence the zero correction. Rotate the micrometer until the fixed and movable jaws contact each other - not too hard and not too soft but just right, you should geta feel for this. Rarely will a micrometer will read zero. You need to figure out the zero error. It may be positive or negative. If the zero error is positive then the zero correction is negative and vicevers. Now open the micrometer and insert the object to be measured and close the micrometer with ideally the same sense of pressure you felt when you found the zero error. Now read the micrometer. You add the zero correction to get the true value.

What is the 'zero error' in vernier calipers and micrometer screw gauge?

The zero error in the vernier calipers and micrometer screw gauge when the O mark on the main scale is not in line with the pointer.


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 .


What are the errors in micrometer screw gauge?

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

How can you correct a positive zero error?

There is no negative zero or positive zero, zero is just zero so you can take it off. For example: 3-2-0= just 3-2


What is zero error of screw gauge?

When the anvil and spindle end are brought in contact, the edge of the circular scale should be at the zero of the sleeve (linear scale) and the zero of the circular scale should be opposite to the datum line of the sleeve. If the zero is not coinciding with the datum line, there will be a positive or negative zero error as shown in figure below. When the anvil and spindle end are brought in contact, the edge of the circular scale should be at the zero of the sleeve (linear scale) and the zero of the circular scale should be opposite to the datum line of the sleeve.

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


What do you understand by zero error of a measuring instrument?

It is a defect in a measuring device (Vernier Callipers & Screw Gauge) & zero error is caused by an incorrect position of the zero point.
