as necessary. In this part we are going to focus on how to measure difference between using ruler and vernier caliper different lengths, using the appropriate equipment. First, here are the most commonly used units for length 1km = 1000m 1m = 100cm
Precaution Step To Avoid Error
1cm = 10mm Back to the topic, the instrument's we need to know aboutare the following ..... 1) Vernier Caliper Vernier caliper is usedto measure short lengths i.e. 0 to 15cm. It is accurate to 0.01 safety using vernier caliper cm. A pair of vernier calipers consists of a Main Scale and a Vernier Scale as shown in the diagram below. The outside jaws, are used to measure the outer dimensions of an object and the inner jaws for the inner ones. The stem is used to measure the depth. To measure , gently grip the object with the straight edges of outside or inside jaws. How to take reading difference using ruler and vernier caliper First read the main scale, and note down the reading before the 0 on the vernier scale, as shown in the diagram below. The reading on it is 2.8 cm, as the .8 after the 2 on the main scale is before the 0 on the vernier scale. For the second place of decimal, look at the vernier scale. Find a marking on the vernier scale that coincides exactly with the a reading on the main scale. In the diagram below, the 6 on the vernier scale coincides exactly with a line on the main scale (it does not matter with which line on the main scale this line coincides). So the second place of the decimal would 6, ie .06. To get the total reading, add the two readings i-e 2.8+.06. The final reading is 2.86cm or 286mm. How to avoid zero error Before using vernier caliper you should close it to find whethera zero error exists or not IF THE SCALESARE LIKE THIS Then there is no zero error Else if: The zero on the vernier scale is on the right side of the zero (on main scale ) then a positive zero error exists . It should be subtracted from the final reading at the end i.e. final reading - po

A vernier caliper outputs measurement readings in centimetres (cm) and it is precise up https://www.miniphysics.com/how-to-read-a-vernier-caliper.html to 2 decimal places (E.g. 1.23 cm).Note: The measurement-reading technique described in this post will be similar for vernier calipers which output measurement readings in inches.Measurement Reading Technique For Vernier CaliperIn order to read the measurement readings from vernier caliper properly, you need to remember two things before we start. For example, if a vernier caliper output a measurement reading of 2.13 cm, this means that:The main scale contributes the main number(s) and one decimal place to the reading (E.g. 2.1 cm, whereby 2 is the main number and 0.1 is the one decimal place number)The vernier scale contributes the second decimal place to the reading (E.g. 0.03 cm)Let's examine the image of the vernier caliper readings above. We will just use a two steps method to get the measurement reading from this:To obtain the main scale reading: Look at the image above, 2.1 cm is to the immediate left of the z
longer/larger objects The measurements are not very precise nor accuratePosition your eyes directly above the markings to avoid parallax errors.Do not start measuring an object from a 0 mark at https://sites.google.com/site/11320yuhan/home/rulerverniercalipersandmicrometerscrewgauge the end of the ruler as the mark may be inaccurate due to wear and tear. Instead, measure from some randomly chosen point and subtract it from the final reading Vernier Calipers 0.1mm Can measure smaller objects with more precision and accuracy Cannot make measurements more than a few centimetresPosition your eyes directly above the markings to avoid parallax errors.Check for vernier caliper 0 errors before measuring with the vernier calipers. If the 0 mark on the main scale and the vernier scale coincides, there is no zero error. If the 0 mark on the vernier scale is slightly to the right, there is a positive zero error and the positive zero error should be subtracted from the reading. If the 0 using ruler and mark on the vernier scale is slightly to the left, there is a negative 0 error and the zero error should be added to the reading.Micrometer screw gauge 0.01mm Can measure very small objects with much precision and accuracy Cannot make measurements more than a few centimetresPosition your eyes directly above the markings to avoid parallax errors.Check for 0 errors before measuring with micrometer screw gauge. If the 0 mark on main scale and the thimble scale coincides, there is no zero error. If the 0 mark on the thimble scale is slightly to the left of the datum line, there is a positive zero error and the positive zero error should be subtracted from the reading. If the 0 mark on the thimble scale is slightly to the left of the right line, there is a negative 0 error and the zero error should be added to the reading.
