In the vernier scale, matches the 23 division with a main scale division, it means 0.02 times 23 divisions, equals to 0.46 millimeters, so, main reading is 54 millimeters plus 0.46 millimeters equals to 54.46 millimeters. Then to find the line on the vernier scale which exactly coincides with the line on the main scale. The Vernier scale of a metric or imperial caliper has again different least counts depending on the type of the Vernier Caliper. Now, see at the given Vernier scale just after taking the main scale reading. (Meaning: get rid of the zero error in the measurement or take into account the zero error), Zero error: – 0.04 cm (negative because the vernier scale is to the left), Measurement without zero error: $3.34 \, – ( \, – 0.04) = 3.38$ cm. The vernier scale of the caliper is divide into fifty equal parts. This will give 2.1 cm + 0.03 cm = 2.13 cm. Now, for taking measurements reading with the vernier scale, the only rule is see the division of the vernier scale that matches exactly with a division of the main scale, multiply it by 0.02 and add the whole number that is in the main scale before the vernier scale zero. Hence, you will have to SUBTRACT 0.04 cm from ALL measurements in order to get the true measurement. (The scales have been enlarged for easier reading.) The Vernier scale is located on the sliding jaw and typically has 25 graduations. I hope this information is useful and helpful to you. Great , -now I can solve any question concerning vernier callipers, It tells that if it’s negative ,instead of reading it to left to right which is the answer will gonna be 0.06 cm, you need to read it right to left and start to 0.01, and the answer will 0.04. On the bottom left, the "blade of the hatchet" are the jaws of the caliper for measuring outside dimensions … How to Read a Vernier (caliper): Looking at an early caliper, you’ll notice that it kinda looks like a tomahawk and has a … However, I think there may be an error in the second figure under “Compensating for Zero Error.” To my reading, the error appears to be – 0.06 cm, not – 0.04 cm. The main scale is divided in all lenght and it have a minimun measuring unit, it is a millimeter, while the vernier scale, takes fractional measure readings of the minimun division of the main scale, that is the millimeter. Home O Level How To Read A Vernier Caliper. The scale contributes to the second decimal place in the reading and represents a thousandth of an inch (0.001), with each .005 inch numbered successively as 0, 5, 10, 15, 20, and 25. The vernier scale divide the millimeter by twenty (1/20), measuring 0.05 mm (five hundredths of a millimeter). 3. Find the actual measurement. Main Scale + Vernier Scale = Result ( 3 x 1mm ) + ( 1.5 x 0.05mm ) = 3 mm + 0.075 mm = 3.075 mm. This virtual vernier caliper is the replica of the metrology tool used in the metalworking industry.

Be sure to ask your instructor if you are still unsure of the correct procedure! If you still do not understand the concept, there is a very useful simulation of the vernier calipers: Vernier Caliper Simulation (Source), Back To Measurement Of Physical Quantities (O Level). if 1 millimeter is divided by fifty equal parts, we obtain 0.02 mm. If matches twenty two divisions of the main scale with the vernier scale zero, and the number ten of the vernier scale matches with a main scale division, we have a twenty two millimeters reading. Two such instruments that are based on a vernier scale which you will use in the laboratory to measure lengths of objects are the vernier callipers and the. So, main reading is: nine millimeters plus 0.26 millimeters equals to 9.26 millimeters. Let’s go through another example to ensure that you understand the above steps: Main scale reading: 10.0 cm (Immediate left of zero), Vernier scale reading: 0.02 cm (Alignment of scale lines), $ \text{Correct reading} = \text{Obtained reading} \, – \, \text{Zero error} $, where $\text{zero error}$ can be either negative (the “0” of vernier scale is left of the “0” of the main scale) or positive (the “0” of vernier scale is right of the “0” of the main scale). HOW TO READ A MEASUREMENT FROM THE SCALES : EXAMPLE 1: The external measurement (diameter) of a round section piece of steel is measured using a vernier caliper, metric scale. Read this just as you would a ruler, measuring to the zero mark on the sliding (Vernier) scale. Drop a comment below if you encounter any difficulties. For whole measurements, you must observe the precise matching of the 0 of the vernier scale with a graduation of the main scale, in addition, the 10 of the vernier scale also matches with a graduation of the main scale. Each numbered line on the bottom scale is 0.1mm extra, each unnumbered line is 0.05mm extra. Note: The measurement-reading technique described in this post will be similar for vernier calipers which output measurement readings in inches. The main metric scale is read first and this shows that there are 13 whole divisions before the 0 on the hundredths scale. There are two versions, a shaded one that is more realistic, and a non-shaded one that is easier to read. The remaining digits are taken from the Vernier scale reading that lines up with any main scale reading, (i.e. Since the zero error is -0.04 cm, this means that all measurements taken by the vernier calipers will be SMALLER by 0.04cm. This vernier caliper has two scales which enable read-ings to a fraction of an inch as in the case of 1/128" graduated vernier (upper scale), or in decimals as in the case of 1/1000" graduated vernier (lower scale). 1.23 cm).
