NanoAmmeter with up to 3kV isolation

Nano-Ammeters can be expensive, and most offer little stand-off voltage capability. For this reason they are placed at the lowest potential in the circuit (at the ground end) to source current. They cannot be used inline (think of a DVM ammeter placed inline reading current) in a high voltage circuit. Steve Covert designed a nano-ammeter that has either a 1kV or 3kV standoff (depending on model). This nano-ammeter has a user friendly touch screen display, as well and full read/write capability via the RS232 serial port.
