Topology: star point-to-point transfer

Supply voltage:

Valid supply voltage range is from about 9.1V (the LTZ falls out of temperature regulation below this point) to 15V (max specified supply voltage for the LT1013).  Let's standardize on 12V for this round.

Supply connection:

The ref has a 2-pin 0.1" female header socket for the supply connection, and will ship with two "pigtails": one with banana plugs and another with croc-clips.

The pigtail connector has been colored silver on the positive lead.  The CAT5 wire is solid-color for negative and white/stripped for positive.  The banana plug heat-shrink is yellow for positive and black for negative.  The croc clips are red for positive and green for negative.

Output connection:

The output pigtail connection is made using a paired set of Mil-Max machine pin headers with solder-cup termination.  These are gold-plated beryllium copper.  With a wrap of tissue, etc, these should track thermally and present minimal thermal EMF.

Format CSV:

Measurements type:

Type 1a: Direct measurement, uncalibrated equipment (unknown uncertainty, over calibration 1year cycle)
Type 1b: Direct measurement, calibrated equipment (in spec)
Type 2: Differential measurement vs calibrated DC-standard (e.g. Fluke 732/Datron 491x) with null-meter connection.

Minimum recommended data sample run: 24 hours
Recommended ambient temperature: +24 C +/-1c
