Part 2: Measuring with the Vernier Calipers + N Hands-On Labs Login HOL- Instance D (1) Whatstep s/12339/experimentation/157553/exercise/13040 4 Count the number of divisions of the Vernier scale and record as N in Data Table 1 5 Calculate the least count of the device using the formula LC = S/N and record in Data Table 1 Note: Some Vernier caliper models have the least count printed at the end of the Vernier scale. Even if the calipers include this number, you must calculate its value manually and include in Data Table 1. 6 Determine the zero error of the calipers by closing the jaws and noting the relative positions of the zeros on the main and Vernier scales 7 Calculate the zero error using the formula ZE - Main Scale Reading +(Vernier Coincidence x LC) and record in Data Table 1 Note: Include the sign of any recorded zero error. If the Vernier zero is to the left of the main scale zero the sign will be negative (-) to the right positive (+) Part 2: Measuring with the Vemier Calipers 8 Secure the large marble in the lower jaws of the Vemier calipers such that each jaw lightly touches the marble 9 Place the calipers and marble on a sheet of paper with your name and date 10 Take a photo clearly displaying the main and Vernier scales of the calipers with your name and date. 11 Insert the photo into Photo 1 12 Record the main scale reading and Vornier coincidence for Trial 1 in Data Table 2 13 Remove the marble, rotate it 1/4 turn, and secure it in the lower jaws of the Vernier calipers such that each jaw lightly touches the marble 14 Record the main scale reading and Vernier coincidence for Trial 2 in Data Table 2 15 Repeat stops 13-14 for two additional trials 16 Calculate the diameter for each measurement trial using the formula Diameter Main Scale Reading (Vornier Coincidence XLC) -ZE 17 Record the diameter of the marble for each trial in Data Table 2 18 Calculate the mean diameter of the marble by averaging the diameter readings for each trial Record the value in cm in Wata - W Where (hp O H X Part 2: Measuring with the Vernier Calipers + N Hands-On Labs Login HOL- Instance D (1) Whatstep s/12339/experimentation/157553/exercise/13040 4 Count the number of divisions of the Vernier scale and record as N in Data Table 1 5 Calculate the least count of the device using the formula LC = S/N and record in Data Table 1 Note: Some Vernier caliper models have the least count printed at the end of the Vernier scale.
