How Do I Remove a Tick?

The zero-scale line is a tool for measuring length (such as a ruler, a tape measure), and the starting point of the scale of the line segment. Measure length tool, zero line tick marks.

Zero tick

In general measurement, the end of the object to be measured should be aligned with the zero scale line for better measurement and

If the zero-scale line is worn, then just take a little, and then use the "last value minus the first value" to get the length of the measured object. If the zero mark is not worn, read the end directly

Measurement with a zero-scale measuring tool than a measurement without a zero-scale
