00:00:00,700 --> 00:00:02,566

Usage of multimeter

2

00:00:03,366 --> 00:00:07,566

In this video we introduce the basic functions of the auto range multimeter

3

00:00:08,900 --> 00:00:13,633

Let me take FLUKE 15B+ automatic multimeter as an example to explain

4

00:00:17,866 --> 00:00:19,400

LCD display

5

00:00:20,066 --> 00:00:21,866

When we use a multimeter to measure,

6

00:00:22,233 --> 00:00:25,000

the display will display the corresponding value,

7

00:00:26,066 --> 00:00:30,133

and we can judge whether the component is good or bad according to the reading

8

00:00:35,266 --> 00:00:37,500

Manual/ automatic range switching

9

00:00:37,800 --> 00:00:41,900

When measuring, we can choose automatic range or manual range

10

00:00:42,566 --> 00:00:43,933

Data hold key

11

00:00:44,433 --> 00:00:49,233

When we press this button, the measured data will be fixed on the screen

12

00:00:50,800 --> 00:00:53,733

AC/ DC mV voltage range,

13

00:00:54,066 --> 00:00:57,266

this range is the AC and DC mV range

14

00:00:57,833 --> 00:00:59,233

DC voltage range

15

00:01:00,066 --> 00:01:02,833

When we measure the DC voltage of the circuit board,

16

00:01:03,400 --> 00:01:07,000

select the DC voltage range, it is automatic range

17

00:01:08,800 --> 00:01:10,133

Backlit button

18

00:01:10,633 --> 00:01:12,666

When we press the backlit button,

19

00:01:13,100 --> 00:01:15,933

the backlight of the display will be turned on

20

00:01:16,733 --> 00:01:18,200

AC voltage range

21

00:01:18,566 --> 00:01:22,300

When we measure AC, we need to use the AC voltage range

22

00:01:22,900 --> 00:01:27,100

For example, when measuring the domestic socket 220V,

23

00:01:27,500 --> 00:01:29,466

we need to adjust to this range

24

00:01:30,566 --> 00:01:31,566

OFF switch

25

00:01:32,900 --> 00:01:35,100

When the multimeter is in the OFF range,

26

00:01:35,200 --> 00:01:37,066

the multimeter will be turned off,

27

00:01:37,700 --> 00:01:40,100

and when it is adjusted to other ranges,

28

00:01:40,366 --> 00:01:42,800

the multimeter will be turned on automatically

29

00:01:43,400 --> 00:01:45,033

Function switch button

30

00:01:45,300 --> 00:01:47,933

This button is used to switch ranges,

31

00:01:48,800 --> 00:01:52,433

because some functions in the multimeter are integrated together

32

00:01:54,300 --> 00:01:56,500

When we need to use different functions,

33

00:01:56,733 --> 00:01:58,966

we can switch through the yellow button

34

00:02:00,166 --> 00:02:02,500

Buzzer/ diode/ ohm range

35

00:02:03,633 --> 00:02:09,100

This icon represents that the 3 functions of the multimeter are integrated in one range

36

00:02:10,600 --> 00:02:12,166

When we use different functions,

37

00:02:12,900 --> 00:02:15,033

we need to switch through the yellow button

38

00:02:17,366 --> 00:02:18,566

Capacitor range

39

00:02:19,033 --> 00:02:23,100

This range is specially used to measure the capacitance value of the capacitor,

40

00:02:23,700 --> 00:02:27,033

which can help us judge whether the capacitor is good or bad

41

00:02:29,500 --> 00:02:32,200

AC/ DC ampere current range

42

00:02:33,733 --> 00:02:39,433

This range is mainly used to measure the size of DC current, or the size of AC current

43

00:02:41,900 --> 00:02:45,300

This range is AC/ DC mA current range

44

00:02:46,633 --> 00:02:51,766

When adjusted to this range, we can measure DC current or AC current

45

00:02:53,166 --> 00:02:57,666

The current measured by this range is relatively small, at the mA level

46

00:03:02,900 --> 00:03:06,666

This range is the AC and DC uA current range,

47

00:03:08,566 --> 00:03:15,333

which can more accurately determine the magnitude of the DC current or the magnitude of the AC current

48

00:03:18,366 --> 00:03:21,466

The 4 jacks below the multimeter are marker jacks

49

00:03:22,366 --> 00:03:24,933

When we use different functions of the multimeter,

50

00:03:25,333 --> 00:03:28,866

we need to insert the markers into the corresponding jacks

51

00:03:29,400 --> 00:03:31,633

If we measure the voltage resistance,

52

00:03:33,066 --> 00:03:35,066

when the component is good or bad,

53

00:03:35,200 --> 00:03:38,833

we need to insert the red marker into the jack of the 惟 icon,

54

00:03:39,566 --> 00:03:42,666

and the black marker should be inserted into the COM jack

55

00:03:43,366 --> 00:03:44,900

If we measure the current,

56

00:03:45,300 --> 00:03:48,766

we need to insert the red marker into the A or mA jack

57

00:03:53,700 --> 00:03:57,466

The middle area belongs to the range selection knob of the multimeter

58

00:03:59,000 --> 00:04:03,500

When we measure different functions, we can measure by adjusting to different ranges

59

00:04:05,200 --> 00:04:07,233

Ok, that's all for this video
