Issue Details

I have an instrument that is connected to GPIB-140B. 
Is the instrument ground isolated from wall power ground via GPIB-140B?


Input GND and Circuit GND for GPIB-140B are connected.

So the key element here is the power supply, if it is connected to the wall power ground, the instrument will be connected to it as well.
