We ramped down the LQ1 and Heidi cycled power on the supply. It was
restarted and seems to have found the correct current. Similar things are
anticipated, stuck bits from the radiation exposure. Erratic behavior of
an unpredictable type. The current output was oscillating about the
desired value of ~2364A. It looked like a stuck bit somewhere that would
not let the supply set to the correct value, so it was setting to the
next value above and then the next value below the desired setting.
