Summary: Fix CO2 profile system at Tower, all okay

When: Fri, 25Jul03, JD-206
Where: Tonzi/Vaira Ranches
Who: Ted Hehn
Weather Clear and hot.

Trip Purpose: CO2 profile system failure

Tonzi Ranch:

CO2 profile system failure due to KNF pump failure. Replace with Brailsford Model TD3L2.

Flow now set to 2.25 lpm during measurement cycle and 2.75 lpm during idle flush cycle.

Run zero/span cycle and check flush time. OK still less that 30 sec to flush sample line 1 clean.

Pressure controller now running at 936.38 mbar, set point at 3.51 volt, press sig at 3.51 v

Perform diagnostics on KNF Neuberger pump in lab. Pump is fine just broken lead wire at motor body strain-relief port. Disassemble motor, remove and replace positive lead wire, clean and reassemble. OK works just like new.

Vaira Ranch:

Check watchdog timer. OK working.
