Log Number: 4543969Logbook(s): Entry Makers: bschaumlBody: 

At the request of DC Power, via Director of Operations, I zeroed the current for all 10 A trims apart from those required for running to the 1D dump and turned off the supplies for all 20 A trims. All rack supplies were left on, per request.

Fig 1-6: Trim Rack Summary as found, when all trims outside the injector were zeroed, and after all downstream of 0I06A were zeroed, interleaved with the configuration for the Global Trim Control script at each step.
