2764	2017-05-11	Lab none	Installed	Tonzi-Floor	Installed at Tonzi Floor tower. Most of the interface settings seemed to be correct (update rate, data stored, CO2/H2O separation), but we could not figure out how to save the sonic analog settings. The Li-7500 v 8.5 software was cut off on our computer monitor.
