How to read a Tresna 50-division vernier caliper gage?

Graduated in inches and millimeters (Direct Reading)
Inch Reading
�?Refer to the lower bar graduations and the inch vernier plate.
�?Inches are numbered in sequence over the full rage of the bar.Every second graduation between the inch lines is numbered and equals .100�? Each bar graduation is .50�?br /> �?The vernier plate is divided into 50 parts , each representing .100�? Every fifth line is numbered -5, 10, 15, 20�?5,50-for easy counting
�?To read the gage,first count how many inches and how many .50″lines you counted on the bar.This is your total reading.
Example
The vernier plate zero line is one inch (1.000�? plus .100″beyond the zero line on the bar, or 1.100�? The 9th graduation on the vernier plate coincides with a line on the bar (as indicated by starts).9×.001(.009�?is therefore added to the 1.100″bar reading, and the total reading is 1.109�?
Millimeter Reading
�?Refer to the upper bar graduations and millimeter vernier plate. Each bar graduations is 1.oomm. Every tenth graduations is numbered in sequence-10 mm,20 mm,30 mm�?.80mm,0.90mm-providing for direct reading in millimeters.
�?The vernier plate is divided into 50 parts, each representing 0.02mm. Every fifth line is numbered in sequenc-0.10mm,0.20mm,0.30mm�?.80mm,0.90mm-providing for direct reading in hundredths of a millimeter
�?To read the gage, first count how many millimeters lie between the zero line on the bar and note its value in hundredths of a millimeter. Add the vernier plate reading in hundredths of a millimeter to the number of millimeters you counted on the bar. This is your total reading

Example
The vernier plate zero line is 28 millimeters beyond the zero line on the bar, and the 0.18mm graduation on the vernier plate coincides with a line on the bar (as indicated by stars)0.18 millimeters is therefore added to the 28mm bar reading, and the total reading is 28.18 millimeter.
