1 00:00:00,960 --> 00:00:03,000 Hello and welcome. 2 00:00:03,000 --> 00:00:09,600 Today I will talk about volt meter basics measuring electricity. 3 00:00:09,630 --> 00:00:18,600 The common function for volt meters is measuring voltage AC and DC and different ranges measuring current 4 00:00:18,720 --> 00:00:26,410 AC and DC in different ranges and measuring resistance in ranges and continuity. 5 00:00:26,580 --> 00:00:32,950 In addition to measuring semiconductor performance transistors and diodes in addition to our rubber 6 00:00:32,990 --> 00:00:35,840 stores. 7 00:00:36,420 --> 00:00:45,200 As you can see in this slide this is one of the basic meters or fault or meter. 8 00:00:45,420 --> 00:00:53,630 This is the meter reading digits and these are the scaling DC voltage scale. 9 00:00:53,820 --> 00:00:58,940 As you can see here there is v plus a sign here. 10 00:00:58,950 --> 00:01:02,760 The sign means DC AC voltage scare. 11 00:01:02,760 --> 00:01:11,790 As you can see the letter plus an AC sign posted a solid out sine functions election as you can see 12 00:01:11,790 --> 00:01:20,490 this probe is used to choose any function from these it will rotate in any direction. 13 00:01:20,590 --> 00:01:21,540 Function selection. 14 00:01:21,540 --> 00:01:25,330 This one is for function selection blobs. 15 00:01:25,530 --> 00:01:30,660 These two blobs are used to measure the components. 16 00:01:30,660 --> 00:01:35,160 These are two wires that are connected to components to be measure. 17 00:01:35,670 --> 00:01:40,880 And as you can see this is a very basic meter. 18 00:01:40,890 --> 00:01:45,180 Now let's talk about other components that this meter might have. 19 00:01:45,180 --> 00:01:57,810 As you can see here there a DC current low as you can see here this measures from 200 micro M bears 20 00:01:58,110 --> 00:02:00,850 to 200 million bear. 21 00:02:00,990 --> 00:02:03,990 This is for small DC current. 22 00:02:04,140 --> 00:02:08,750 This is for large or high DC currents 10 amps. 23 00:02:08,790 --> 00:02:10,500 Uh this is the DOE checker. 24 00:02:10,530 --> 00:02:17,940 As you can see this uh there is a drawing here and this is the transistor checker. 25 00:02:17,970 --> 00:02:20,140 This is for resistance measuring. 26 00:02:20,160 --> 00:02:30,020 As you can see starting from 200 to 2000 Kato on you can choose any of these to measure them. 27 00:02:30,690 --> 00:02:39,300 And I think that this is the most common type fault or meters of our type might have other functions 28 00:02:39,800 --> 00:02:45,160 and depending on how much your budget is you can choose any. 29 00:02:45,270 --> 00:02:47,540 As you can see there's three blobs here. 30 00:02:47,550 --> 00:02:54,750 This one is for a for a form which I think I'm better in D.C. and this one is for measuring voltage 31 00:02:54,840 --> 00:02:57,950 or small current. 32 00:02:57,960 --> 00:03:01,860 And this is the common must be connected all the time. 33 00:03:01,890 --> 00:03:05,970 This one is moving from here to here depending on the amount that I want to read. 34 00:03:06,480 --> 00:03:12,900 And as you can see it says then a DC which means that this will be used to measure the umber or the 35 00:03:12,900 --> 00:03:22,640 current in D.C. while this one is used without voltage resistance and the current and Millie and bear. 36 00:03:22,800 --> 00:03:27,270 So you have to be careful in dealing with these three blobs. 37 00:03:27,270 --> 00:03:31,300 You have to connect each one to the right place. 38 00:03:31,440 --> 00:03:39,500 As mentioned here now um we want to use it in practicum. 39 00:03:39,570 --> 00:03:47,550 We will use in the experiment sections but you need to understand how it works and how to use it. 40 00:03:47,580 --> 00:03:55,890 Let's see the Volt on meter basics with we mentioned error that will be used to measure voltage voltage 41 00:03:55,890 --> 00:04:04,740 type scaling safety physical and equipment for measuring current current types killing plus safety. 42 00:04:04,800 --> 00:04:14,730 Now uh you have to be careful using about meter or Volt or meter you count so much resistance and do 43 00:04:14,730 --> 00:04:16,400 different scaling. 44 00:04:16,590 --> 00:04:21,930 We will do this in practice or practical experiment. 45 00:04:21,990 --> 00:04:24,520 Next. 46 00:04:25,020 --> 00:04:31,620 But now you are ready to actually use this meter and we will cover these three functions. 47 00:04:31,620 --> 00:04:37,820 I will show you how to measure voltage then how to measure current then how to measure resistance in 48 00:04:37,830 --> 00:04:42,540 the slides or theoretical manner at first then in a practical manner. 49 00:04:42,810 --> 00:04:43,740 That's it for now. 50 00:04:43,740 --> 00:04:44,730 Thanks for watching.
