then makes the voltage and current measurements, calculates the

3.10.2.6
PSwitch Installed
This picklist value indicates whether or not a persistent switch is
installed. If YES is selected, the PSwitch Current Detect, PSwitch
Current, PSwitch Heated Time, PSwitch Cooled Time, PSw P/S
Ramp Rate, and PSwitch Cooling Gain settings are made available
within the Load submenu. If NO is selected, these settings are
not
made available within the Load submenu and the
PERSIST.
SWITCH CONTROL
key becomes inoperable. The default value is
YES unless preset by AMI to match a specific superconducting
magnet.
3.10.2.7
PSwitch Current Detect (mA)
This function will automatically determine the proper value of
heater current in a persistent switch installed on a magnet
connected to the power supply system. The power supply should be
energized and at zero current. When the
ENTER
key is pressed to
start the process, the following occurs:
1. The persistent switch current is set to 0.1 mA.
2. The power supply current is ramped to 2 A at 0.1 A/sec.
3. After the power supply current reaches 2 A, the persistent switch
current is slowly increased (as shown on the display) until the
Model 430 Programmer detects a change in the load, indicative of
the persistent switch transitioning from superconducting to
resistive. Before this transition is detected, the display will show
the heater current value as it is increased in the persistent switch
