WEATHER COMMENT: Thu Jun 24 16:56:52 GMT 1999
Clear sky, wind=5 mph from the West, temp=52 F.
CHIP COMMENT: Thu Jun 24 17:00:43 GMT 1999
The repaired Filter Temperature Controller arrived.  I'll install it and
turn it on and watch the temperature, with luck it will be correctly
setup and I'll be able to collect some data later in the day.
LOW-L COMMENT: Thu Jun 24 17:12:08 GMT 1999
Tape file count was at 70, so I stopped the program and removed L00606 from 
drive #0 and installed L00608 there.  Data currently going to L00607 in
drive #1.
CHIP COMMENT: Thu Jun 24 17:53:18 GMT 1999
Temperature controller installed, setpoint=3.077 vdc, sensor=9.93 vdc,
output=9.99 vdc.  CHIP temperature field on GUI monitor is at 24.081 C,
it was at around 22.0 C before I installed the temperature controller.
CHIP COMMENT: Thu Jun 24 19:21:46 GMT 1999
Temp finally overshot and is at 34.651 and climbing.
CHIP COMMENT: Thu Jun 24 20:34:52 GMT 1999
It doesn't appear to have the correct setpoint.  Temp=38.328. setpoint=3.077,
sensor=5.72, output=10.0, all in vdc.
COMMENT: Thu Jun 24 20:46:48 GMT 1999
Extended the dome slot around 2015 ut.
CHIP COMMENT: Thu Jun 24 21:08:01 GMT 1999
I turned off the temperature controller since it didn't start bringing the 
temperature back down.  I'll check the sensor voltage with the controller
on as the temperature passes through the correct range, I'm sure it
isn't between 0-5 vdc and I think it needs to be for the control loop
to work right.  I'll then take down the controller and reset the jumper
and setpoint to what they were before the guy at Meadowlark changed them.
CHIP COMMENT: Thu Jun 24 23:04:27 GMT 1999
I set the setpoint and the "jumpers" (actually pins soldered together,
lots of work to get to those, had to remove entire board, etc) to the
previous setpoint of 0.644 and using 100 microamps.  Meadowlark
had it set to a setpoint of 3.077 and sensor circuit resistance of
1 milliamp, with that resistance the control loop for the temperature
would not have worked because the sensor voltage would have been up
around 6.70 vdc, that is outside the control loop working range of
0 to 5 vdc.  Now we'll have a sensor voltage of about .670 vdc, 2.5 vdc
is probably ideal but that's the best we'll get with the sensor we
are using and the choices of sensor circuit resistance available.
The temperature is at 29.621 and climbing, I'll wait and see if it
stabilizes.  I'll also run the instrument to what the data look like.

This ran all day without crashing.
COMMENT: Thu Jun 24 23:24:11 GMT 1999
Rotated the dome 180 degrees to get sun on CHIP.
CHIP COMMENT: Thu Jun 24 23:58:46 GMT 1999
temperature just passed through the high end of the ideal range, it's at
34.546 C and climbing slowly.  We want it between 34.3 and 34.5 C

CHIP COMMENT: Fri Jun 25 00:26:24 GMT 1999
Yeehah, the temperature turned around at 36.282 and started going back down.
That means there is some control and it won't get hotter than 36.282.  So
I can go home now and leave it on overnight.  I'm not sure where it will
stabilize, Eric will find out tomorrow.
CHIP COMMENT: Fri Jun 25 00:35:25 GMT 1999
All but a few images look bad due to incorrect filter temperature, tomorrow
they may be great again.
