Installation
Power-Up Procedure
19. Turn off the power supply.
20. Reset the stability setting and ramp rate of the Model 430
Programmer to an appropriate value for the magnet to be operated.
Then turn off the Model 430.
21. Remove the short from the power supply leads and connect the
leads to the magnet current leads of the magnet.
After successful completion of this test, the system is ready for operation
with a superconducting magnet. Refer to the ramping function example
presented in section 3.14 on page 85 for a discussion of the various
available ramping methods.
