LI-7500A 75H-2182 2012-08-16 Mayberry Gas Analyzer CO2/H2O Removed Lab none Removed from the Mayberry permanent tower for calibration. Replaced by sn 0065 that was recently upgraded to a 7500A interface.
LI-7500A 0065 2012-08-16 Lab none Installed Mayberry Gas Analyzer CO2/H2O Installed on the Mayberry permanent tower. sn 2182 was removed for calibration. The existing coefficeints and zero/span values were downloaded from the 7550 box. The new coefficients and zero/span values were uploaded to the 7550 box. The existing head sn 2182 was removed and this IRGA was installed. All looked well.
LI-7500A 0065 2012-08-09 Lab none Installed Lab none This IRGA has recently been upgraded to a 7500A interface. I tried to install it on the 7550 box at Twitchell but it sent the 7550 box into a reboot cycle. So now it is back in the lab to be tried on another tower.

The upgrade went smoothly, o-rings were greased, the internal chemicals were changed, coefficients were manually entered in the LI-7550 box (sn AIU-0674). The gain potentiometer was adjusted, per instructions, about a half turn before maxing out. The AGC was 50.0 before adjusting and 43.75 afterwards. See initial calibration this date. A subsequent calibration will be done in two days to let the internal chemicals settle.
