As a quick check of the upper sections of the wire loop in the reaction chain, I suspended the PenRe (recall the ERM was already suspended) from the UIM.  Although not a true test of the chain due to cabling interferences with the LSAT, I wanted to verify that no error large enough to justify a replacement loop existed.  In fact, it looked as good as I have seen on any previous Quad.  Satisfied with the results, I locked the PenRe and ERM for the weekend.
