Objectives:
This procedure checks that the instrument is still in good operational condition post landing. It will also get a background measurement at the end. Use to check if TA has developed any shorts.
Sol 96 – Running to check EGA Channel 3 health and see if we can get a TA manifold pressure post Carrier valve leaking. Changed the last Sweep 38 to run at 3500V and modified the TA manifold heater to 65C from 20C.
