Vernier height gauges are one of the two main types of tools used to make accurate vertical measurements. As i don't recognize the position you're, i will use imperial length as a practise guide, yet a metric vernier is only a similar, yet different gadgets. Imperial height gauges measure heights up to a maximum of 48" using a main scale and vernier scale graduated to read to 0.001". The main scale reading is that to the left of the zero on the vernier scale. Sub Code: 2141901 MMM - Lab 6 Experiment No. The other type is typically referred to as an electronic height gauge. Please read this manual thoroughly before use for proper operation. The left height gauge has the vernier scale, while the right one is an electronic height gauge with a digital readout. 1 - Outside jaws: used to take external . EXPERIMENT positive or negative, depending upon whether the zero of vernier scale lies to the right or to the left of the zero of the main scale. APPLICATIONS AND FEATURES Ideal for marking and measuring work for molds, jigs, and tooling. Figure 9.3: Position of the notch and Vernier height gauge to set the datum. Vernier provides teachers with the tools to encourage curiosity in all students – high quality science probeware, experiment software, and resources. The relationship between the flow rate and water depth above the weir can be derive… Vernier height gauge used to measure vertical dimension from reference ground. Sliding main carriage for fast, easy adjustment. Repeat the experiment with the V-notch weir plate, but with 5 mm increments in water surface elevation. 1) This is similar to vernier height gauge. The vernier reading is found by locating the best aligned lines between the two scales. In the case of a digital vernier caliper the following additional steps should be taken: Bring the jaws in contact with each other and then press the on/off button. ��ŜR�s����TF�9'7Qrk7k�qR�5A��c�|ǩ����qr�Q�3<6&ڜ1��`��2B�~�Ԕ���h�9�pZV��3��[����ַ�M|��41�R�ƃ1������CL�9ìP�\? So, they'll be a bit harder to read to .001" than later Starrett, Mitutoyo, etc. Weirs can be broad-crested, short-crested, or sharp-crested. Vernier Caliper 2) Measurement of Small Lengths By Micrometer Calipers The most widely used device for the accurate measurement of small dimensions is the micrometer caliper, as shown below. gages with those features. measures of objects . Describe the procedure of the experiment. E1.2 (ii) and (iii). Collect seven head and discharge readings for each weir. : 03 AIM: To Find Taper of Tapered Job Using Sine Bar And Slip Gauges. A Vernier height gauge is a measuring device used either for determining the height of something or for the repetitive marking of items to be worked on.

I doubt you need extreme flatness, but a friend was doing MSEE research assisting one of the laser profs in the ’70s. Specification of a vernier height gauge is made by specifying the range of measurement, type of scale required and any particular requirement in regard to the type of vernier desired. That said, I don't believe their height gauges had either the long form vernier or the magnifier (as in later Mitutoyo vernier height gages). 3 Linear measurement using dial gauge, slip gauge, and calibration of dial gauge 4 Use of gear teeth, Vernier Calipers and checking the chordal addendum and chordal height of spur gear. Close the regulating valve, stop the pump, and then replace the weir with the V-notch. APPARATUS: Tapered job, Sine bar, Slip gauges, Spirit level, Surface leveling table, Surface plate. Table 1.Experimental reading (Calibration data) Reading of measuring jaws at position (mm) Limit (mm) Sr. no Standard length in (mm) Upper Central Lower Average reading (mm) Min. so that you seem the position the 0 of the interior scale is, alongside the substantial scale. Easy to read scale using 3x magnifying lens. A digital height gauge and granite surface plate should come fairly early in your Metrology investment schedule given how useful they can be. This is shown by the Fig. 1. My asian vernier height gauge is calibrated in inches. Experiment 1 Measurement Fig.5. Digital height gauges may be more expensive than their vernier counterparts, but typically take less training or expertise to read correctly. To become familiar with the use of micrometer calipers for the accurate measurement of small lengths. EXPERIMENT # 1. Helps old eyes..
