View history entry 3283 for Licor LI-7700 sn: TG1-0224

Date: 2018-01-12
From: Lab - none
To: Lab - none
Title: Adjusted
Notes: This 7700 has an unlocked reference signal (the reference and signal waveforms were not synced). I talked with James at Licor and changed the Laser Start Temp from 29.8 to 25.5 in the factory settings (Help > About > Factory). To find the new start temperature, I did a Wide Scan (Help > About > Wide Scan > Start), which goes through temperature 0-50 deg C. There is a graph and table of results, where you can pinpoint the reference lock temperature. During the Wide Scan, some of the factory settings changed, so I reset those (changed Delta 1 from 100 back to 41). Licor has the original factory settings on file.
