FAULT 1 (RESISTOR BURN)

OBJECTIVE

- To analyze and solve the problem happen during build this project.

CONTENT

FAULT 1 

There have two connections wire of the same color this had been changes between 240V and 5V input.  From the fault, resistor become burn because overload the input supply and LCD cannot display the any value.

TROUBLESHOOTING FAULT 1 (RESISTOR BURN)

To trace the fault, check the circuit:
 i. Check the PIC burn or not. The PIC it still in good condition.

ii. Check  the connection on the track layout.

It is connected and has no damage or failure of the connection on track.

iii. Troubleshoot Power Meter. It still in good condition.

CONCLUSION

To solve the fault change the new resistor, 10kΩ and Crystal 20Mhz. so the problem has been resolved and the project run smoothly.

Replace of new component (Crystal = 20MHz) 

Replace of new component (Resistor = 10kΩ )
