Description: | From 8/18 through 8/20 the logger battery voltage (vBatt) periodically jumps in voltage
with noise on all differential measurements. The qc fields caught most of the
down_long_hemisp MAX failures but the bad short_direct_normal, down_short_hemisp and
down_short_diffuse_hemisp values were not flagged.
Noise returned on 8/22, 8/25-26 and 8/27-28.
Site Ops checked and re-routed the Sky stand grounds on 8/21 and performed additional
ground re-work on 8/28. After that date, noise has not returned to the Skystand logger
instruments. |
