keyword=tech: Confusing non-zero Q3 reback on LHRS, Q3 Supply is logged as "OFF"According to the halog entry by Jack (207397), the LHRS Q3 has no power to it and is OFF with the control modules removeed. This entry is supported by the power supply screen from Hall A Tools (below).
Nevertheless, we are getting significant non-zero momentum and current readings from the Hall A Tools screen (below) and, most troubling, a positive polarity reading.
This, to put is mildly, is both confusing and troubling. I have informed the run coordinator and left a message with Makis.
Any information from experts would be appreciated.
