necessary correction can be made to find the correct measurement
the correction which is made to get correct measurement after zero error
· 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.
the correction was wrong
It is the value which the vernier shows when it should actually read zero. This may be because the vernier is worn.
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 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.
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.
The question is incomplete and cannot be answered as stated. Correction Curve for what? Please restate the question.
An advantage of correction fluid is that you can use it to cover up mistakes. You can also write on the fluid whenever it dries.
Thank you for your correction is the correct way to use your proper English. You are welcome for my correction.
Yes.
