Summary: New Tower computer, calibrate LI-800 bad solenoid

When: Mon,Tue 1Nov04 JD-305
Where: Tonzi Ranch
Who: Ted Hehn
Weather cool and clear

Trip Purpose Zero/span LI800 - change sonic at tower & data download

Tonzi Ranch:
1Nov04 11:08 The VIA computer (Larry) is on. Gillsonic is displayed but traces show no movement. The date is 306 the time is 10:41:01.

Clean lenses on LI7500. Did not change water channel reading: 0.00

Install USB to RS232 adapters to interface to the LI800 and CR10x7.

Place CR10x on com1 with a surge suppressor. Place sonic and LI800 on Usb/RS232 adapters.

11:17 shut down gillsonic to run zero/span on LI800
428.7 ppm CO2 cyl# sa3583
nitrogen cyl# cc102170 with soda lime scrubber stack on output

LI800 shows 958 mBar and cell temp = 52.6
Sample stream temp = 48.65 sample cell = 44.38

Pressure controller shows 960 mBar

Solenoid #5 (calibration) on the CO2 profile system failed to open repeatedly and must be replaced.

Misc Notes
Buy another solenoid for co2 profile system
