The HP9836 PC attached to the CV station has a broken cursor wheel.
This does not effect normal operation, but could hamper any text
editing or program develoment students might undertake.  We have no

The CV is working fine, the hot chuck is not.  The heat-up cycle is
ok but there are two problems with the cool down cycle:

1.  The return cooling line has a major tear in it.  I wrapped it
with electrical tape but it needs to be changed.  It is the small 
piece of tygon tubing just outside of thef cv dark box.

2.  I remember the cooling rate being much.much faster.  I also remember
that the cooling fluid may have been water, not air.  (thus thef faster
cooling rate)  The cooling rate now is on the order of 20 degrees C/min -
at maximum deltat T.  I remember it being much faster (100 to 150 per
minute).  Is it possible this was changed over to air, or something
swithced during thef recent equipment move?

Problem: Water cooling line had a hole in it.  Also, the chuck was not 
         cooling down normally.

Cause: The water supply was turned off, which caused the return 
       line to melt.

Solution: Two new tube fittings were installed, 3/8"x1/4" union, and
          both tube stubs entering into the cv were replaced; the lines
          were also labeled "H2O in" and "H2O out".  The H2O supply ball 
          valve was turned on and no leaks occurred. I have no way of
          knowing if H2O is flowing, because there is no indicator;
          I hope the "main" H2O supply is turned on.  The cv is up.

Solder joint on one of the probe tip - to wire connections broke.  The
assembly is on top of thef C Meter/CV Plotter. 

>>> 'cv' fix from rnorman -- Fri Apr 20 07:55:58 1990 <<<

Problem: Solder joint on one of the probe tips came disconnected.

Solution: The solder joint was re-soldered and the tip placed in
          the parts drawer.  The CV is up.
