During the initial sign checking and electronics shake-down for H2 ITMY. When we first got ITMY hooked up we observed an apparent Sign shift for the input signals "H2:SUS-ITMY_M0_OSEMINF_F1_IN1" etc. During my sign check, offset sign check, etc.: All OSEM Basis and Euler Basis offsets were inversed. I requested a positive offset, but observed a negative offset in the suspension. I inverted all OSEMOUTF_GAINS for M0 and R0. Ran through the sign and initialization checks in the beginning of the metal-build testing procedure and confirmed all was well.
