First Light: AD2702SD +/-10V Precision Reference

[GEOelectronics]

This is a test of old but never used AD2702SD Mil-spec version with bipolar output and metal case.

Conditions:
+/- 15.0 DCV from bench power supply
First power on-
+Port = 10.000345
-Port= -9.9991 on calibrated Keysight 34470A

There are provided trimmer ports for both + and - outputs with +/- 30mV swing. This has not been implemented on this test jig yet. When it is, it will be switchable so further temp testing  can be done with and without it in. There is a derating factor if it is in.  However I have not started work on chamber yet.

"1-Dot" label refers to a tiny red paint dot marked on the top, so I can tell it apart from the second one in lie for testing
