I forgot to turn off the power of system before I did some continuity test using a multimeter.
Basically an +-V dual supply was powering a transducer. Transducer was outputting very small offset like 100mV and had almost 8k output impedance so I'm not worried about that much.
But I also did continuity test between V+ and V-; V+ and GND; V- and GND ect.
When I each time heard continuity sound I noticed that I forgot to turn off the power. So I turned off and did the same test.
But many hours later I was afraid if I did damage the power supply.
What happens if nodes +15V and -15V or + for instance is checked with continuity of a multimeter when the power is on? I know that would be short if it were a wire but is there possibility power supply is not damaged?
