Steve_hi Posted May 1, 2007 Report Share Posted May 1, 2007 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?

audioguru Posted May 1, 2007 Report Share Posted May 1, 2007 To measure continuity you must remove the batteries. Then the negative supply will not be shorted to 0V and the positive supply will not be shorted to 0V. Quote Link to comment Share on other sites More sharing options...
