Why a micrometer provides more positive reading than vernier calipers?
SanuMishragp2901
Micrometer is having a ratchet to rotate which is pre-loaded to get standard thrust while measurement, whereas in the case of a vernier the accuracy of measurement depend on the pressure each individual applying while the measurement.

What type of micrometer is easiest to read?
A digital micrometer is the easiest to read as it displays the exact reading on a screen.
HOW TO USE A screw-thread micrometer?
First calibrate the micrometer by dialing the spindle to zero and adjusting the anvil until it is flush against the spindle. Measure the screw until the ratchet begins to click and take the first reading. This reading can then be compared to a machining book to verify the pitch diameter.
How does one avoid lifting of the bridge of the depth micrometer?
To avoid lifting of the bridge of the depth micrometer, make sure that the spindle is correctly positioned before taking a reading. The spindle should be parallel to the base of the depth micrometer and should be positioned directly over the object being measured. Make sure that the object being measured is firmly supported and that the work surface is free of debris that may interfere with the depth micrometer’s operation. Before taking a reading, check that the anvil and spindle are perfectly aligned with each other. Avoid pressing down on the depth micrometer too hard as this can cause the bridge to lift. Always use the correct size micrometer for the job and the correct size anvil for the object being measured. If the bridge does start to lift, stop and correct the problem before taking any further readings. Before taking a reading, always make sure that the depth micrometer is properly zeroed. When using a depth micrometer, always keep your hand away from the spindle and anvil. Make sure that the depth micrometer is properly maintained and stored in a dry, clean environment. Lastly, always use the depth micrometer with care and caution to avoid any damage or inaccuracy.
What is the fullform of SAX parser in HTML?
SAX (Simple API for XML) is a serial access parser API for XML. SAX provides a mechanism for reading data from an XML document. It is a popular alternative to the Document Object Model (DOM).
Why reading is a largely visual process?
normally, good eyesight is required in good reading.

How do you read a reading in micrometer?
u poo OR ELS
What is positive zero error in a micrometer?
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.
To what decimal can you estimate the reading on a micrometer?
My micrometer reads out to ten-thousandths of an inch.EX: .2501".This is 250 thousandths plus 1-ten thousandths of an inch.I never guesstimate a reading...Hope this helps
How tight is the thimble turned when testing zero on a micrometer?
All you need to do is make contact. Tightening will give you a false reading and eventually damage the micrometer.
When reading a small-hole gauge how is the micrometer reading taken in relation to the split in the ball on the split or 90 degrees to it?
90 degrees
What is the expected Error using micrometer?
the spindle must be tighten to avoid slightly changes on the reading

What instrument can be used to measure both internal and external diameter?
vernier calliper scale. give us reading upto two places right side from decimal
What are the many positive for reading that are available to modern man?
positive avenues for reading
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
