Notes:
01/30/1015 - Calibration for West bay EX81 (inbound flow meter) appears to be incorrect.
02/03/2015 - Since the rain event, the Center bay EX81 appears to be continuing to generate data (without flow). Investigation of this anomaly to proceed...

SDI-12 maintenance
01/30/2015 - West bay - Removed power to a subset of 5TM sensors in Zone I (CH16) for troubleshooting. It appears something is causing the bus to crash.
02/03/2015 - West bay - Continuing testing of Zone I. Currently have only half of the power jumpers in place in order to perform reliability testing on a subset of 5TMs.

EX81 Flow meter re-wiring
02/03/2015 - All 3 EX81 - Tied shield drain wire to EX81 housing and panel earth ground. Data generated around 12:00 are artificial (due to re-wiring).

02/09/2015 - At approximately 08:00 East bay above ground temp/RH probe ( LEO-E_4_0_1_HMP60 ) was damaged by gantry. Probe was torn off it's mount due to insufficient clearance after raising the mast (mast was not raised high enough) and operating the gantry up the hill slope. Data for this probe is (since time of damage) invalid.
