Plan for returning from COVID shutdown
- Follow manufacturers "Check out" procedure for new power supply which was delivered during shutdown
- Measure resistance to ground for both coils
- Install latest new power supply, add additional circuitry
- Test power supplies in both current and voltage control mode
- Look at PS output on scope, with and without RF on.
- Test NMR in both voltage and current mode
- Ensure Labview is ready to go for either configuration
