level history to date:
levels were first hooked up Wed (I think) to 4m uw. Since the "pigtail"
cable was labeled backwards, these channels were hooked up to the 10m
channels (ragwort 106&107) and pitch and roll were probably reversed.
On Thurs, I did several tests (including loosening the back guys to
check the change in angle and ended up with levels hooked up to the
10m uw on the right channels. The result of these tests were that
I think the BNCs on the display unit are labeled correctly (since
"P" changed by .4 deg (from .42 tight to .00 loose) and "R" changed
by .1 deg (from 1.2 tight to 1.1 loose) with the back guy loosened.
This means that "Y" on the display is roll and "X" is pitch. This
should all be confirmed at the end of the experiment.
On Fri (again, I'm not sure of the day) I switched back to the 4m uw
now on the right channels.
Today (Sat) I noticed that xcockpit showed that pitch.4m had changed
from about -1.8 to -1.0 overnight - I'll check the guy wires today.
Also, the cables are labeled strangly in the level box. At the
moment they are:
Red "18m" goes to the 10m uw
Red unlabeled goes to the 4m uw
BNC "A" is ragwort:107 (roll.10m)
BNC "B" is ragwort:106 (pitch.10m)
BNC "C" is ragwort:105 (roll.4m)
BNC "D" is ragwort:104 (pitch.4m)
I should get to relabeling these cables today, since this is too
much for a normal human (myself included) to understand.

I just labeled all of the cables also, so anyone should be able to
do this task now.

- 142: LEVELS , Site none, Thu 28-Feb-1991 07:50:58 MST, pitch.4m had a level shift
pitch.4m had a level shift
I've seen this before. It happened sometime this shift - probably from 1200-1400 GMT.
The pitch output increased by about .5 degree and is now steady at a new value. Since
there is no appreciable wind (1m/s) it is hard to imagine that this is real. The
shift seems to have been instantaneous (no ramp visible on xcockpit).
This will require further investigation.

The cabling, analog cable, from the level signals
was changed to a short cable today. This was done inorder
to have an analog cable for the Vaisala probe attached to
the 4m Kypton. Refer to logbook enter on operations, for today,
for more information.
