how to use vernier caliper step by step

Use your thumb to slide the jaws open and closed. b) The Vernier Scale Reading: A caliper has a main scale and sliding (Vernier) scale. Step 1: How to Use a Vernier Caliper A vernier caliper uses a vernier scale too achieve greater precision. Now you can easily read the dimension in relax mode. You can get some practice sheets at http://weldnotes.com#Vernier #WeldNotes Record the measured value in the worksheet of object’s step. 8/15/13. Release the jaws of the vernier caliper by scrolling thumb screw till the right upper jaw touches the lower step. This value should then be added to the final reading. (It was often necessary.) Now, push the base of the main scale down to the mouth of the mortise. Print out the template. Measurement of Object’s Steps With A Vernier Caliper: The combination of left side head of the Vernier caliper and the face of the upper jaw at right hand are normally employed to read step measurements. This site uses Akismet to reduce spam. We have already introduced the vernier caliper as a simple but brilliant tool for taking precise measurements which a normal ruler is incapable of. But once you know about it, you will find many uses for step measurement. Grip the item that you opt to measure and fix & tighten the lower jaws at objects edges by sufficiently scrolling the thumb screw. Loosen the screw or screws holding the sliding scale in place. Step 1: Measure the ambient temperature and record it. Your email address will not be published. Manually operated traditional analogue vernier calipers are standard for highly precise manual calculation and theory if vernier scale. On an inch Vernier caliper, each increment on the main scale represents one-tenth (.1) of an inch. Step 1 – Rest Sliding Jaw Opposing Upper Step Of Item Release the caliper gradually. Shut the jaws totally so that the caliper displays zero reading. Rotate the lock screw to make the jaws fixed and take away the item and measure reading of object. Taking Outside Measurements Using a Vernier Caliper: Measurement of depth with the help of a Vernier caliper: How To Take Inner Measurements Using A Vernier Caliper: How To Measure The Length of Cylinder Using a Vernier Caliper? Place the sliding jaw on the upper step of the workpiece, then open the caliper until the fixed jaw contacts the lower step. While you increase the jaws with thumb screw, the depth gauge will touch the deep surface . Next note the distance travelled by the other mark. Next place the correct size micrometer standard onto the surface plate and extend the caliper above it, then close the caliper until it is just touching it. In this article we will be taking an in depth look at the main features of a caliper and how to use one to take a reading. For example if the least value is 0.01 mm and the 7, Mitutoyo Digital Vernier Caliper List With Specifications. Use the large jaws to measure objects from the outside; these jaws point to you as you read the caliper. 3.Lock the clamp screw so that the jaws don't move 4.On the vernier scale is a small number 0. Note: The measurement-reading technique described in this post will be similar for vernier calipers which output measurement readings in inches. In order to ready your vernier caliper for measurement, first loosen the lock screw positioned on the upper side of the caliper by turning it counter clockwise. Clean the caliper before use. How To Take Inner Measurements Using A Vernier Caliper: Inner measurements for example the diameter of a pipe is measured with the upper jaws of the vernier caliper. Move the sliding scale until the larger jaws of the caliper are fully pressed against each other. Don 't worry if it falls between 2 numbers - for example between 7 and 8 . The zero line on the sliding part of the scale is actually a pointer. 2. Reading the metric scale of the vernier caliper is a two-step process. This can be done by dividing the value of one division by the number of lines present in between. This Wikipedia article on the vernier scale gives all the information possibly needed, but in short, it is a ruler with an added secondary scale which gives extra precision. Release the internal jaws by rotating thumb screw till the outer of each jaw connects the boundaries of the gap. It is very important for us to use the vernier caliper correctly to ensure an accurate measurement.Thus,here are the steps for using the vernier caliper correctly. There are three classifications based on how to read the caliper: 1) Vernier caliper, 2) Dial caliper, and 3) Digital caliper. Vernier calipers: If you have two opposite sides of an object and want to measure their distance then using Vernier calipers is the best way. Internal measurement. Open the caliper slightly. Taking Outside Measurements Using a Vernier Caliper: Vernier calipers are generally utilized to take measurements outside of an object for example small widths, lengths or diameters. 3. How To Use Vernier Caliper In Right Way Step-by-Steps. Preparing the Instrument: In order to ready your vernier caliper for measurement, first loosen the lock screw positioned on the upper side of the caliper by turning it counter clockwise. A Vernier caliper consists of two sets of jaws. Step 2 – Make Sure Item Is Fixed Straight In Jaws. Step 1 – Tighten Lower Jaws Of Vernier Caliper At Object’s Edges. They have a least count of 0.05mm. From the start to the end, the steps can be divided into some detailed ideas. If the zero mark on the vernier scale is aligned with a mark after zero on the main scale it is known as a positive zero error and if it is aligned before the zero it is known as a negative zero error. Make sure that the zero lines of the vernier scale coincide with the zero lines of the main scale when the external jaws are closed. So for a caliper with 1 mm as the smallest reading on the main scale, the vernier scale’s divisions would represent 0.1 mm. The final step is to add the main scale and vernier readings to get the final measurement. Required fields are marked *. A Vernier caliper has two rulers: the main scale and the sliding Vernier scale. Make sure the measuring faces are clean. Use the smaller jaws to measure holes and internal spaces, such as the inside of a pipe. Note down the measured value & record it in the work sheet you have made for measuring depth of the object. Clamp nut carries to the beam. Cut it out. Read the measured value and record it in your worksheet for that object. Notice how it has movable jaws and two measuring scales. 3:44. However if the zero lines up before the main scale zero then you will need to note the position of another mark that aligns somewhere after the main scale zero. Alow the caliper to align with the hole or rip that is being measured. The main scale reading is the division just before where the zero mark of the vernier scale is aligned. Measurement Reading Technique For Vernier Caliper Rotate the screws to fix the jaws in order to remove your item and take down the reading. The larger ones are used to hold objects between them and measure their outer diameter while the smaller ones on top are inserted into an opening to measure internal diameters. Then slide the jaws so that the two zeros align. In this article we will be taking an in depth look at the main features of a caliper and how to use one to take a reading. We have already introduced the vernier caliper as a simple but brilliant tool for taking precise measurements which a normal ruler is incapable of. How To Use Vernier Calipers - Watch and Learn #59 - YouTube For example if the zero mark aligns with 1 mm on the main scale then you need to subtract 1 mm from the final reading. 3. One of the measuring scales moves with the jaws. Rest the sliding jaw opposing upper step of the item being measured. Once you have determined the value of one division, you can also find out the distance represented by the smallest divisions on the vernier scale. For example if the other mark was previously on 0.4 and ended up at 1.2 then the zero error will be 1.2-0.4 = 0.8 mm. Rotate the thumb screw steadily till the last part of the end of the beam scale comes in touch with the upper facade of the depth area. If two adjacent tick marks on the sliding scale look equally aligned with their counterparts on the fixed scale, then the reading is half way between the two marks. For example if there are ten divisions per marking in the vernier scale then the smallest division will represent 0.1/10 = 0.01 mm.
