Temperature control unit of DRM is not heating devloper.  With
power on and cool on, the developer temperature drops (<10C) even
when the heater light is on.  Turning cool off, the developer 
returns to room temp (~20C) after several hours.

It appears the heater cartridge on the drm has failed; a
new one needs to be ordered.  I left the old one next to the
temperature controller in GL4.

The heater in the chiller/heater unit is defective and a new one
has been ordered. The vendor is Forma Scientific @ 1-800-848-3080.
PN 600605, 500 watt cartridge heater with flange. It is in stock
and will be shipped 2 day air freight. It should be here early next
week and will be installed. I have the drm manual in the office while
I make a file copy. A clean room version will be returned to GL-4.

The DRM heater cartridge has been replaced and the DRM is working
again and available for use.

The drm is in the process of repair; however, no one has reported a
problem. Users should report all problems associated with even if
they are qualified to make these repairs.
The drm is down pending a problem update.

The drm detector saturates when measuring highly reflective
substrates.  I have added a potentiometer to the lamp
power supply, allowing the light intensity to be varied.
The drm has been reassembled and is now operational.

I will be working with the detector circuit on the drm to characterize
the new variable halogen source.  This requires taking the cover off
and disabling the wet process end.
