Circuit portable digital monitor blood pressure?
HICKS I'm using portable digital blood pressure monitor. Has number power input 6 V. I was wrong as a pin adapter 12 V, and I see a smoke coming out of it and off. When I check the circuit, I found that some as the diode or fuse as the structure of about 10 mm ^ 2 which is the rectangular area in the shape has been blown. I think it's a fuse and I join the two subject being connected with the help of a cable, not turn on and starts to warm. The display also gives information of the systolic – diastolic BP – 102 and pulse. Please, tell me what is the part that is burnt, so I can replace it.
There a lot of parts on the circuit board and without a good layout and design circuit is very difficult to identify the party. Zoom in on the help. It could be a resistor, capacitor, diode or other component.
