Received the product, it is verified that the integrated circuits do not work. Communicated to the seller with this message: Good Morning. Integrated circuits, defective. Not original and with manufacturing defect or FAKE. Pin nº 9, + Vcc, not protected by internal zener as indicated in the Data Sheet. Compared to the original, it has a low-value inverse leakage resistance that renders the integrated inoperative, with excessive consumption that can cause damage to the equipment power supply. 30/01 22:53 I am an electronics professional, responsible for one of the most important Repair Technical Services in Spain, with a large laboratory with all kinds of instruments. I await clarification and possible solution. His reply is as follows: 31/01 11:19 I don't understand technology Little serious seller and not recommended. |
