Total thickness measurement (c) measured with a Vernier at a distance of approximately one-fourth of the length from both ends by measuring each side in opposite position 2 and then record the results.
Measuring total thickness (c) measured by Vernier at a distance of about a quarter of the length of the two side-by-side measurements per second in the opposite position, and then record the results.
Measuring the overall thickness (c) was measured with vernier at a distance of about a quarter of the length of both ends by measuring its 2 value in the position of the opposite. Then record.
