Backslash is a character on a keyboard. Backlash is the inherent slackness in the mechanical parts of a micrometer which allow an extremely small movement of the operating barrel without any corresponding movement of the measuring 'anvil' of the micrometer.
A micrometer (or micrometer screw gauge) measures the volume of a screw.
In vernier calipers, zero error is when the jaws of the caliper do not close properly when they are in contact without measuring anything, resulting in a measurement that is not accurate. In a micrometer screw gauge, zero error occurs when the flat end of the spindle does not perfectly align with the reference line on the sleeve at zero reading, leading to inaccurate measurements.

The principle of a micrometer is based on the rotation of a screw to precisely measure small distances. The screw moves a spindle, which is connected to a scale that indicates the measurement. By calibrating the micrometer scale, accurate readings can be obtained.
Put it between two jaw piece micrometer. Screw close movable jaw. And read on a micrometer ruler.
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.

it should be clean and dry there should be no error the thimble shouldnt be too tight
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.
The pitch of the precision ground spindle screw on a micrometer is typically 0.5mm.
To remove zero error from a micrometer, first ensure that the micrometer is closed completely without any object between the measuring surfaces. Then, check the reading on the scale; if it does not read zero, note the error value. Adjust the micrometer’s zero setting, if it has one, or account for the error in future measurements by subtracting the zero error from your readings. Finally, recalibrate the device regularly to maintain accuracy.
The instrument is named a micrometer screw because it uses a calibrated screw mechanism to make precise measurements in micrometers (one millionth of a meter). The screw has finely spaced threads that allow for accurate adjustment and measurement of small distances.
