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 is the noun form of correction?
The noun form of correction might be the word correction. A correction is defined as a change that is made in order to create a specific result. When describing this change, the word correction would be a noun.
How many syllables in correction?
"Correction" has 3 syllables. Cor-rec-tion.
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.
How would you write the numeral 0.00000000006 in words?
Zero point zero zero zero zero zero zero zero zero zero zero six.
Why do you use zero correction?
necessary correction can be made to find the correct measurement
What is the zero correction and meniscus correction in hydrometer analysis?
· 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.
Why do we use zero correction?

What is the zero correction of the vernier?
It is the value which the vernier shows when it should actually read zero. This may be because the vernier is worn.
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 .
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.
Can an eyeglass have zero power?
Of course. Simply fit a set of smart frames with lenses fabricated from what is known in the trade as "window glass", and you have designer eye-glasses with zero correction. One wonders why a person would go to that trouble and expense if his vision needed no correction, but ours is not to reason why.
How do you put correction into a sentence?
He made a correction. The correction was made. A correction is needed.

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 is positive eror in screw gauge how it can be remove?
Actually when we keep both the studs touch each other then zero of the head scale should lie in line with the pitch line. Then no zero error If suppose instead 0 of the head scale to be in line with pitch line, say 5 is in line with pitch line then this is taken as positive error. So correction has to be -5. This means that whatever be the reading of the head scale as we insert an object between the studs, then it would 5 more. So that 5 is to be subtracted. Hence negative correction Same way if the pitch line has 97 of head scale in line, then -3 is zero error. Hence correction +3. This means that while taking reading during experiment we get the head scale reading always 3 less. Hence we have correction as +3
