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.

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.
