On July 30th the NHC diagnostic signals were tested:

- 9 pin CPC: a shorting plug was installed on the hot side - continuity check results were as expected

- 4 pin CPCs:  snake camera installed in both hot side connectors with portable monitor on cold side - both connectors worked as expected

- USB: laptop connected on hot side, USB mouse connected on cold side - worked as expected

- Ethernet: laptop connected on hot side, cold side connected to building ethernet port - connection to network worked as expected

- SHV: a shunt was installed on the hot side - a short circuit was measured from the cold side as expected
            with no shunt installed the line was Megger tested: 1.63 G-ohms recorded @ 1000V

The control panel switches for the in-cell receptacles were also tested.  Each switch (a - d) worked as expected.

On July 31st the gas supply solenoid valves were tested.  60psi air was hooked to each solenoid inlet.  With the valve closed there was no air flow.  When each push-button or switch was activated air flow was observed through the correct solenoid.
