I just bought this product to measure the energy of my mobile battery. I am from CS background, so don't have enough information. Can anybody help me, I have Xprotolab product and circuit board. To supply power to this circuit, i will use micro_USB connected to my laptop. But the problem is where I'm gonna put the cable on circuit board to measure the signal. Mobile Battery has positive and negative terminal so where should i put the other end of the cable on circuit board?I don't know much about electronice. Any help would be highly appreciated
