Hi
I made an ECG and when I do a continuity test for the positive battery terminal and the # 8 pins of the TL072's i have continuity, but not on the center tap of the 2 9 v batteries, and when I check for continuity of the negative terminal and the number 4 pins of the op amps ihave continuity but I also have continuity with the negatve battery and the center tap of the 2 batteries, is that supposed to be like that is ground and negative the same?
