How to Check NE555 timer IC with multimeter

How to test 555 timer ic using multimeter
This video is about NE 555 timer IC.In this video I explain how we can check NE 555 ic using Digital Multimeter.After watching this video you will be able to check an IC whether it is Functional or Not.

Helpful - thank you

why do we connect positive terminal to the ground pin?

[@jazzyfreshgames]

what do the numbers mean? i can see that bad numbers are way bigger, but why does that mean they are broken

[@user-eb3ir5pe7r]

Thanks for the video. But why, the values ​​of IC number 3 makes it damaged. For IC number 2 I understand that it is damaged because there is a reading which did not give a value. Thank you for answering my question.

My friend, IC 555 consists of resistor and transistor.If its values ​​change, it is no longer IC555 And it turns into a new IC. So it is not defective, but it no longer has the necessary functionality.

یک روش دیگر هم هست. مقاومت بین پایه های ۱ و ۵ باید حدود ۱۰ کیلو اهم و مقاومت بین پایه های ۵ و ۸ باید حدود ۵ کیلو اهم باشد.

Good 👍 And 1-8= 15K

​@@SparkMind1what if it is olny 14.33k?

[@thorhedderich]

So what is the conclusion?

[@SparkMind1]

I showed the result at the end of the video

The internal diagram of this IC can be found by typing "555 internal circuit".

@@SparkMind1 you didn't explain why those other two were bad and what are the standard numbers we should be looking for in order to know if any pins are off.
