Got My Guildline 9975 Back From Repair

[Hawaii596]

Thanks to a fellow PMEL for loan of the full manual (which is nearly impossible to get a copy of these days). 

I got my Thomas 1 Ohm out and doing some test operations.  I'm slowly but surely working on a system calibration (where you check and adjust bridge balance.

And per input from a person from MI (they did the repairs), he recommended using fire alarm cable (solid copper, shielded, twisted pair).  I have a 500 foot spool on order for about $75 from Newark.

He said I could buy cables from them, but that they're expensive.  To get started, these work very well, and are what a lot of people use for resistance bridge measurements.

My next dilemma is getting the temperature stabilized in the room where I'll be using it.  Either that, or I'll have to do some uncertainty analysis, determine how much instability is added to my measurements, and add that to my measurement uncertainty - that will be fun.  I have some "woodshed" ideas in that regard.  I'm thinking of removing the AC vents that lead into that room and keep the door shut during measurements.  I'll have to monitor and document what happens.

In any case, it will be an adventure.

As I say to my subordinates (in the morning before my Ritalin kicks in -legally prescribed, of course), "Calibration is about Passion."
