Sondrestrom Lidar Operation Log

Operator(s) : E.Gudmundsson
Purpose : Routine data collection
Date(s) : 980321 - 980322
File(s) : L9803210 - L9803213
Comments : Had some problems starting up. The Rayleigh heat exchanger did not show
anything on led's or temperature display. After some time I found a blown 0.5A
fuse in the control circuit located under the control panel. Started taking data
with setup 0 at 22:39 UT and the Rayleigh system was on at 01:26 UT (setup 1)
Logfile : L9803210.log
