Isolated Bench PSU: Important “Variac” Fuse Upgrade - Make sure you do this!!

ERRATA:
- Apologies! I meant to say that the banana sockets for the DMM to measure current is in parallel with the SPST switch with Red protective cap. Activating the switch, closes one of the parallel branches, allowing current to flow. If this left in the default "off" position, no current can flow, unless the DMM is attached.
