- 97: SURFACE, Site ISS3, Wed 07-Dec-2011 04:36:13 GMT, Rain gauge not functioning
The rain gauge is broken, and likely has been since at least early November. Monday we checked the connections, which appeared fine, and it started recording again. Walter also confirmed the tip-switch was not stuck or broken (yesterday). Today, lots of rain and no tips.
May be a minor issue if the WXT and CoCoRas station are sufficient.

Didn't see any diagrams, etc. for the Campbell/IRT when debugging the bad cable, so before I forget here's the pin assignments.
CR10 cable to Amp IRT-Cannon
AG yellow 8 H
E3 Orange 4 F verify these 2, but both excitations
Green 6 D
5H Red 3 C
5L Blk 1 A (This was the culprit)
6H Wht 5 G
6L Purple 7 E
- 36: SURFACE, Site ISS3, Sun 16-Oct-2011 20:45:58 GMT, Power outage in helium carrier
2000 UTC 16 OCTOBER 2011
Noticed power to helium crate had switched off when aspirator wouldn't turn on. Unplugged the cable and reset the breaker switch on the outlet to the left of the office carrier door (outside), but it trips again when you plug the cable back in. There is probably a circuit short with all of the rain, so leaving it unplugged until daylight can assist in figuring out the problem. Just means a headlamp is necessary to get helium.
2330 UTC UPDATE
Plugged back in and reset breaker; aspirator and crate lighting now back on and appear to both be working without tripping the circuit. No rain for last 4-5 hours.
Seems that left-most outlet is less-susceptible to rain/trip issues than right one
- 30: SURFACE, Site ISS3, Thu 13-Oct-2011 12:50:40 GMT, Sfc Station: IRT down/up, fixed, swapped
12Oct11 22:30Z, (13Oct 4:30local)
The IRT went completely down.
13Oct11 12:50Z (18:50 local)
Removed Eppley Pyrgeometer s/n 32686
Installed Eppley Pyrgeometer s/n 38809 (original unit)
Comments:
I appear to have located the problem. There was an intermittent wire on signal 5L inside the campbell box. This was the black wire from the bulkhead to the actual logger. It had apparently be crushed in the backshell strain relief clamp and finally (thermally?) opened up completely.
Original Unit:
Now has the good battery from the spare. I did this instead of fiddling with the coefficients in the campbell dld file since I haven't found what the spare unit's values are.
Keep an eye on it...

12Oct11 15:00-16:05 Local (9:00-10:05Z)
Net Radiometer:
Swapped desiccant.
Replaced domes.
The desiccant was shot, and there was water inside the tube. The desiccant actually appeared plugged with some remaining good in the middle but 'red-caked' on either ends. There was some water inside the desiccant tube and I drained the housing too.
The domes had condensation inside and because of that and the above, decided to swap them. The screws were slightly loose. The O-Rings were dry and hard to seat. Probably could use some vacuum or plumbers grease, new seals/rings.
Radiometer data will be effected during this period while I was working on the stand.

12Oct11 04:45Z, 10:45local
Removed Eppley Pyrgeometer s/n 28809
Installed Eppley Pyrgeometer s/n 32686 (spare unit)
Reason:
The original unit has been acting up with some jumping around of the signals. It's believed to be within the sensor/cable there rather than in the logger connections.
Coefficients Not Yet Changed:
Trying new sensor first to see if signals have stabilized before changing them.
Desiccant:
The reserve is getting a bit 'stale' but still acceptable. Some crystals have turned.
