- ISS10 is not the model used in SpinQuest. We expect the spec is almost similar but sometims different.

Output Validation

- V to the switch heaters (Y1 and YZ vs Common)
- Measured = -5.7 V.
- Manual = -12 V.
- V to the coil (+VE vs -VE)
- Measured = 0 V (<0.1 V) normally. But -13.1 V when the big knob to any position (like Z0 and Z1) except "MAIN COIL HEATER".
- Manual = +4 V.
- The output voltages were found active, although they were different from the manual spec. It is possible that they are fine for the operation, because our usage is special in the past test and the SpinQuest run, namely the shim coil need not be energized but only inductive when the main coil is ramped up.
