In this case it is found to be:Īn important consideration while dealing with vernier calipers is to check for zero errors and adjust accordingly. The final step is to simply add the two values to obtain the final reading. For example in the above picture the line corresponding to 3 on the vernier scale aligns perfectly so the vernier scale reading is 0.3mm. Just look for the line on the vernier scale which is perfectly aligned with mark on the main scale. Reading the vernier scale requires a bit of observational skill and since it is the most important step of the process we suggest you do this very carefully. so that gives a least count of 0.02 or 0.05mm respectively. The total length of the scale represents 1 mm. The Vernier scale is graduated in either 20 or 50 increments. In the example we can see that the exact value is slightly greater than 2.1 but how much? This will be determined by the vernier scale reading. The main scale has given us a number but it is not the exact value of the measurement. In the example below the value immediately before the zero mark is 2.1 cm. To find out the main scale reading look at the value on the scale directly on the left of the zero mark of the vernier scale. In case of metric units the smallest value that can be measured by the main scale is 1mm. It is graduated in millimetres or inches. The Main scale is obviously named because it is the primary scale of a vernier caliper. To read this value the first step is: Obtain Main Scale Reading: Examples of these activities include exploring potential jobs in related careers, interactive quizzes, lectures, workshops, study groups, and more.We will assume that you have taken the necessary steps before measurement and positioned the calipers correctly according to the required dimension which needs to be measured and now the scales of the caliper have moved a certain distance to indicate the measured value. Second Life was chosen for this project because it allows students access to Project IMPACT 'island' or virtual land to participate in activities that align with their classes. The virtual world can be accessed freely via Linden Lab's own client programs, or via alternative Third Party Viewers. Second Life is an online virtual world, developed by Linden Lab. These questions have been converted for use outside Second Life. The purpose of these multiple choice quizzes is to orient, quiz, and assess the student’s knowledge of precision measurement tools such as Micrometers, Dial Calipers, and Scales.
