Product Name: Desktop 1156 CPU Tester 1156 LIGHT load test combo

Product Category: chip-level maintenance tools - motherboard repair tools - motherboard dummy load

Product Description:

Note: without batteries

 

⑴ dummy load Function and Use: It is mainly used to measure the voltage at each point CPU is normal, normal before the true CPU (thus avoiding the motherboard repair process in the CPU burn). He can also be used to measure the CPU North Bridge or other channels leading to 64 data lines and 32 address lines are normal, is an essential tool for maintenance of the motherboard. 

⑵ its use of methods and steps: aiming to be done before the six CPU detection step (on the false premise that the load powered)  
test dummy load on the core voltage is normal. 
Test dummy load on reset [RESET #] and voltage is normal. 
Test dummy load on the clock and voltage is normal. (Measured with an oscilloscope clock on the dummy load if there is wave, there are waves indicate normal)  
test dummy load on the PG signal voltage is normal. 
Test dummy load on the 1V reference voltage is normal. 
Measured core power supply on the motherboard down tube C pole whether there three waves (measured with an oscilloscope down tube  
C to see if there are three waves can refer to core power supply)  
Note: When the above normal after the CPU really can be more than a
