Before the beginning of the CAP, the background subtracted 0th order count rate of HZ43 was ~ 2.7 cps. We raised the bottom and top plates by 1 step each, and the background subtracted rate went to ~ 3.2 cps. A decision was made to raise the voltage on the bottom and top plate by an additional step each. The final background subtracted rate was ~ 3.5 cps. No hotspots were noted on the detector. The instrument was left at these new settings until 13:30UT, when commanding in the daily loads performed a swap to the HRC-S. The HRC and flight ops teams verified that the HRC-I was switched off.
