Hi experts,
I built a standard summing circuit using LM318 following the schematic as shown. The only ‘load’ at Vout is the probe.
My problem is, when I first power it on, the scope came up nothing, but when I disconnect and reconnect the probe, suddenly I start seeing the expect waveform and the circuit works.
What could cause the problem?
