From about 1635-1735 I reconfigured pressure yet again.  (See 11b signal for exact times.)

- 11b transducer removed and inserted into the CHATS system (which was buried yet again) to monitor Pref (in parallel with the Vaisala PTB220).

- a leak installed into the far end of the AHATS reservoir (black tube).  About 4m of the 1/16" line is attached, mostly coiled up in the ground, but the open end is exposed.

We'll see what <this> looks like...
