Summary: Zero/span Li800.

When: Wed., 13Jun03, JD-164
Where: Tonzi/Vaira Ranches
Who: Ted Hehn
Weather Clear, warm and breezy. Grass mostly dead. Yellow and purple flowers still doing well.

Trip Purpose: Zero/span Li800

11:00 arrive, install Measur12.dld in CO2 profile cr10X7. Removed Measure6.dld.

Port Flow Pressure
1 2.75 941
2 2.75 941
3 2.70 941
4 2.8 941

Run zero air and LI800 shows –6.8 ppm CO2
CR10x7 shows 0.723 volts

Run span gas 426ppm CO2 and LI800 shows 413.2
CR10X7 shows 413.1

Forgot to bring LI800 serial cable- get one from Jackson Radioshack with wrong gender. Buy gender adapter at PC connection.

Did not have LI800 software on auxiliary PC. Remove tower flux PC for LI800 zero/span sequence.

Set LI800 zero and span. OK all worked well.

Measur12.dld failed and locked up. Remove it and reinstall Measure6.dld on CR10X7.

Reinstall tower flux PC and initiate gillsonic.exe. OK all appears well.

Nitrogen cyl pressure = 900
CO2 cyl press = 1850

Misc Notes
Bring LI800 serial cable
Bring PCMCIA COM port card
Install Li800 software on all PCs
Rewrite Measure6.dld to include manual port activation for LI800 zero/span sequence.
