I recently acquired a used BK Precision 1660 triple output power supply.
Upon powering it up, I did some basic voltage checks. On both the master and slave outputs, voltage between positive and negative terminals were correct.
However, on the slave output, I actually measured 0.25V between the positive terminal and ground, and also -0.25V between the negative terminal and ground. This doesn't happen on the master output.
Is this normal?
I'm somewhat new to these things but something tells me this isn't right
