Summary: Download data, install new tower power enclosure, repair data logger.

When: 20-22 Mar03, JD-79-81
Where: Tonzi/Vaira Ranches
Who: Ted Hehn
Weather Clear, cool & calm

Trip Purpose: Tower CR23X/enclosure taking on water – repair and replace data logger. Install new tower power regulator enclosure.

Tonzi Ranch: 21Mar03 09:00

Download all data to flash card.

Remove Zip drive from site.

Knock plastic plug out of top of tower CR23x enclosure. It was leaking and allowing water to contaminate 23x. Scrape all surfaces clean and refill hole with regular epoxy.

Remove & replace CR23x6 data logger and reprogram with new version of PC WATCHDOG timer program. This program has Time Event Driven Software (TEDS) moved to 1st program table so it will no longer be interrupted by residing in the 2nd program table.

Lost communication from floor pc to all data loggers. Begin diagnostics: Remove CR23x6 coax lead from MD9 and retry communication – no help. Remove CR10x 4 & 5 coax lead from floor pc system – no help. Remove coax line at floor pc that connects loggers 2,3 & 6 and regain communication with loggers 4 & 5. Problem therefore lies with leads/loggers 2,3 6. Begin diagnostics on leads/loggers 2,3 & 6. Discovered that cr10x2 had locked up and I could not get any response with manual keyboard/display. Remove power from cr10x2 and power up again. Ok, system now fully operational.
