1015 Fed Cricket 4 pellets.
Filled LN2 cold trap.
1100 Removed DCRC 31. Installed DCRC 32 and 31 into Dib 2 and Dib 3, respectively.
1115 Powered DCRC31. Monitor temperature change.
1145
1230 Power DCRC32 to prep tuning QET bias for Dib 3/ DCRC31.
Reset power for DCRC33. Zap SQUIDs.
1303 Set up timing link.
1305 Board 32 disconnected.
1311 Reset timing link. It seems that with all boards connected that the power available should read 94 W.
Completed tuning of Dib 3.
Take IbIs measurements for Dib 3/DCRC 31/ Ch. A.
