View history entry 3279 for Licor LI-7700 sn: TG1-0224

Date: 2018-01-10
From: Lab - none
To: Lab - none
Title: Adjusted
Notes: Checked the sensor in the lab, and the temperature reading was fine. However, there was an error "Reference signal is UNLOCKED," and CH4 was reading ~0.05 umol/mol. The diagnostics tab showed that the signal and reference waveforms were not synced. I changed the temperature control to manual, adjusted the laser temperature from 30.6 to 26.0 so that the waveforms were synced, and changed the temperature control back to automatic.
