When the anvil and spindle end are brought in contact, the edge of the circular scale should be at the zero of the sleeve (linear scale) and the zero of the circular scale should be opposite to the datum line of the sleeve. If the zero is not coinciding with the datum line, there will be a positive or negative zero error as shown in figure below.

The zero error of a screw gauge is the error that occurs when the zero mark of the thimble does not align perfectly with the reference line of the sleeve. This error can lead to incorrect measurements as it affects the starting point of measurement. It is important to calibrate and adjust the screw gauge to eliminate zero error.
No, a zero error in a screw gauge indicates that the initial reading is not starting from zero. So, 47mm cannot be a zero error unless the screw gauge is not calibrated correctly.
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.
To remove an error in a screw gauge, you can start by ensuring that the gauge is clean and free from any debris. Check the calibration of the gauge using a calibration standard. If the error persists, it may be necessary to have the gauge professionally adjusted or repaired.
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
It is a defect in a measuring device (Vernier Callipers & Screw Gauge) & zero error is caused by an incorrect position of the zero point.

Take a measurement with nothing in the gauge. That reading is the zero-error.
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 .

Zero correction in a screw gauge refers to the adjustment needed to compensate for any slight misalignment between the zero mark on the main scale and the zero mark on the circular scale. This correction ensures accurate measurements are taken by aligning the two zero points when no object is being measured.
The conclusion of a screw gauge experiment is typically a statement summarizing the precision and accuracy of the measurements taken using the screw gauge. It may also include any sources of error or uncertainty that were identified during the experiment. Overall, the conclusion highlights the importance of using the screw gauge as a tool for making precise measurements in scientific applications.
To take readings from a micrometer screw gauge, first, place the object between the anvil and the spindle. Then, gently rotate the thimble until the object is securely held. Next, read the main scale value aligned with the sleeve and note the number of the smallest division on the thimble to get the final reading.
A screw gauge has a smaller pitch than a Vernier caliper, which allows for more precise measurements. The screw gauge also provides a digital reading, which reduces human error in reading measurements. Additionally, the screw gauge has a finer scale that allows for more accurate readings compared to a Vernier caliper.
The screw gauge is commonly called a micrometer screw gauge because it is a precise measuring instrument that utilizes a calibrated screw for accurately measuring small dimensions with high accuracy, typically up to 0.01 mm or even smaller. The term "micrometer" signifies its ability to measure very small distances, often in micrometers (1 micrometer = 0.001 mm).
