00:00:00,766 --> 00:00:02,666

How to use the location diagram

2

00:00:03,333 --> 00:00:08,166

In this lesson, we mainly learn how to use the location diagram in actual maintenance

3

00:00:08,600 --> 00:00:13,300

In actual maintenance, the location diagram is mainly used in two aspects

4

00:00:16,033 --> 00:00:20,100

First, check the chip or component parameters in the circuit diagram

5

00:00:22,900 --> 00:00:25,933

Second, check the actual components

6

00:00:31,533 --> 00:00:35,766

Let's first take a look at how to view the information of the component in the drawing

7

00:00:38,300 --> 00:00:44,100

When repairing, we need to analyze the theory of components, or when replacing components,

8

00:00:44,533 --> 00:00:47,033

we need to check the parameters of components

9

00:00:47,866 --> 00:00:51,133

First determine the position of the chip in the actual object,

10

00:00:51,533 --> 00:00:53,633

then open the location diagram,

11

00:00:56,166 --> 00:00:58,633

find the number of the corresponding component,

12

00:00:59,066 --> 00:01:01,166

and then search for the number in the drawing

13

00:01:09,466 --> 00:01:13,566

After searching, if the number is the same, it means the component,

14

00:01:13,866 --> 00:01:16,200

and we can view its parameter information

15

00:01:19,466 --> 00:01:25,233

In the second case, find the corresponding components in the real object through the schematic diagram

16

00:01:25,800 --> 00:01:28,466

For example, after analyzing the principle,

17

00:01:28,800 --> 00:01:32,800

it is determined that this capacitor or this resistor may be damaged,

18

00:01:33,500 --> 00:01:37,633

how to find the corresponding resistor or capacitor in the actual object?

19

00:01:38,900 --> 00:01:42,133

First find the component number in the schematic diagram,

20

00:01:43,466 --> 00:01:46,733

and then search for the corresponding number in the location diagram

21

00:01:48,633 --> 00:01:53,266

After searching, the location diagram will show the location of the component

22

00:01:55,000 --> 00:01:58,566

Then find the corresponding position according to the actual object,

23

00:01:59,300 --> 00:02:03,466

and the component at the corresponding position is the component marked in the drawing

24

00:02:04,166 --> 00:02:06,133

Ok, that's all for this video
