Hello, I measured voltage of non inverting pin3 of opamp with a standard voltmeter while pin3 was floating and opamp had been confgured as follower but it had about 13V output voltage(pin 6) enen when I grounded pin3 via a 100MOhm the result did not change. this opamp had input current of about 100 fA. can someone explain the phenomena and possibly the way it can be fixed, please?
PS-opamp is not damaged, I repeated the experiment with a few new ones but result was the same.
