Summary: HMP fan dead - replaced, Changes to CR23x program including zeroing calibration radiometer channels. todo list

When: Thurs 16Dec04 JD-351
Where: Vaira Ranch
Who: Ted Hehn

Vaira Ranch:
Thurs 12:48 arrive T&RH fan not functional, replace with new fan. Older fan had 0.160 amp draw. New fan has 0.25 amp draw..

Panel T = 16
Batt volt = 11.89 + .4 = 12.3

Solar reg
Volt = 13.6 charge & battery status LED both lit

System voltage line to CR23x is configured for a single ended measurement. Reconfigure for DE measurement: add signal return lead. Note that this lead has been chewed on by the critters. Move system volt signal lead from SE channel 24 to DE channel 5. Similarly, move pc status leads from SE channel 23 to DE channel 6 and modify program: DE channels 5 & 6 were for the 4way radiometer calibration (PRT) but leave MUX sequencing intact for the rad measurements to keep channel sequencing the same. I set the multipliers for those rad measurements to 0.0.

Note: water droplets present on top inside of CR23x enclosure. NDVI signal leads pinched in top of door. Move them to the side of door.

Solar Reg
Batt volt 12.9
Array amp 5.7
Load 0.7 PC off now

Saturday 10:00 all appears well

Misc Notes
Cat walks for Vaira 23x and Tonzi 3 places at soil moisture profile probes
Order T&RH end cap filters.
Replace solar reg enclosure at Vaira and solder all connections as corrosion sets in
Order 30 amp solar regulator as we have no spares.
Bring wide variety of fuses to tower site
CR23x6 enclosure/insulation on tower is deteriorating and need to be replaced.
Leave 2 T&RH fans in storage at tower site.
Bring protractor to floor and check solar panel angle â€“ appear to be at 45 degree
Edit site status report form to include checking T&RH fans at all sites.
Replace ribbon cable on cr23x6 with shielded version
