Field Measurements

Plan for returning from CODIV shutdown

    • Follow manufactureres "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
