Per the Shift Check Sheet (for Thursday's task), I went and checked on the Crystal & Diode Chillers for the PSL.  The Crystal Chiller was not at maximum, so I added 125mL (basically to get the water's meniscus close to the "MAX" level).  NOTE:  according to the notepad, this was filled on 12/16 with 125mL also.

Diode Chiller was fine (no red error light).
