I would like to do some testing on our Refrig unit.

Minimum would be to monitor icebox temperature and voltage to compressor so
that I can see on-off cycle and resulting temperature vs time for a 1-2 day
period.

If possible, I would like to add current to compressor and temperature in
area where compressor/condenser is located.

Since this is just a fact finding test, I would like to keep the cost down.

I have seen individual USB temperature and voltage loggers at Lascar
Electronics. For example:

http://makeashorterlink.com/?V2BD2567D and

http://makeashorterlink.com/?P5CD2567D

Does anyone know of a Canadian or US source and especially for a unit that
might accept several inputs?

Someone suggested earlier on rec.boats.cruising that I just use a video
camera, but I need to do this over 24-48 hrs to determine why my refrig
controller at times seems to go into hibernation!

Any ideas welcomed.

I have been looking at loggers from these companies.....

You should be able to see the temperature change as compressor goes on off
with some delay.
