BRSX has been running with it's heater almost maxed out at 9V for a while, meaning the hot pad has been sitting at about 50 C for a long time, so Tuesday I reduced the voltage to 7V and made an adjustment to the pico mass adjuster. Changing the heater voltage takes ~1day to settle out, the mass adjustment only took an hour or so to damp down. I adjusted the picomotor using the > button on the middle lower left control keypad on the overview in -1000 step increments. -1000 to engage the yoke, -2000 step adjustment to the mass, +1000 steps to disengage the yoke. This moved the dc position from around 0 to ~-6000. The 2V drop on the heater has now settled out to about +6000, and reduced the hot pad temp to about 40C, and reduced the igloo temp .3C . I think VEA temps trend up as weather cools off outside, higher temps push the dc position negative on this BRS, so I think I will wait a few weeks before making any more adjustments.
