first scans with LV problem solved! |
|
|
This is the first time with LV buffer problem solved (see Elog ID: 184). Before the PMT signals were out of sync with the wavelength data!
We concluded to scan with step sizes of 0.002nm, scan range of 0.5nm (f
nm), dwelltime = 150(5s), loops = 2 (approx.: 30min measurements).

Runs after this have the right cobra set value but propably the wrong WM data until 10.04.22 12:44 (see also ID:198) |
