I can see the logic in Rojos point, and in practice I see large differences in leakage current measurements between the device being powered off and on, personally I would think it pointless measuring leakage currents from a device that is not powered on. The interesting thing is, there is still many differences of opinion in interpretation from highly experienced technicians on how to routinely test electro-medical devices. Why should this be the case after all these years, personally Ive given up trying to figure it out as it seems to be a matter of opinion depending on where you work.
