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 function of spindle in micrometer screw gauge?
The spindle in a micrometer screw gauge is responsible for making contact with the object being measured and moving along the pitch scale to take measurements. It is rotated to bring the object into contact with the anvil, allowing for precise measurements of small objects with high accuracy.
What is micrometer screw gauge used for?
A micrometer , sometimes known as a micrometer screw gauge, is a device incorporating a calibrated screw used widely for precise measurement of small distances in mechanical engineering and machining as well as most mechanical trades, along with other metrological instruments such as dial, vernier, and digital calipers. Micrometers are similar in use to vernier calipers but are more precise although the modern digital caliper has blurred the distinction between them.A micrometer is also used to measure the diameter of very small objects that a vernier calliper can't measure for example a screw or a piece of wire.This instrument is mainly used by mechanics.
What is the precautions you should take when using a micrometer screw gauge?
it should be clean and dry there should be no error the thimble shouldnt be too tight
What are the precautions you should take when using a micrometer?
Handle the micrometer with clean hands to prevent contamination. Avoid over-tightening when measuring to prevent damage to the micrometer or the object being measured. Store the micrometer in a protective case to prevent dust and debris from affecting its accuracy. Regularly calibrate and maintain the micrometer for accurate measurements.
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
Why is screw gauge commonly called as micrometer screw gauge?
A micrometer screw gauge is commonly known as a micrometer. This is a form of calipers used for measuring small dimensions. Screw gauge in extensively used in the engineering field for obtaining precision measurements. The article describes the principle and main parts of a basic micrometer screw gauge.

How do you find zero error of screw gauge?
Take a measurement with nothing in the gauge. That reading is the zero-error.
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 can you find a trigger assembly screw for a 12 gauge double barrel serial No 36002?
Take it to a gunsmith

How do you find the cal on a Spanish black powder rifle?
It is normally stamped on the barrel. If it is not, take it to a gunsmith. The smith can use a gauge or micrometer to measure the bore diameter, and tell you the right size ball and patch to use.

Why do your air condition hoses freez up after the ac has been on for about twinty minets?
Did you do the air condition service yourself? If so did you add proper amount of 134a and compressor oil? What are the gauge readings on the hi and low pressure sides? (and include outdoor temp on the day you take readings)
