Bonjour a tous:
Checking the new Keysight 34465A all within sec as far as I can see but temperature is the last one.
Testing is only for the Type K thermocouples we use.: Omega, Fluke and others
Using the Omega mini K connectors.
I made a gold plated banana to Type K female adapter/extender with Omega type K TC wire.
Use old Fluke 51 handheld 2 1/2 digit Tep meter for reality checking. (also Fischer mercury thermometers, poor resolution).
The various TCs seem to match ~ 0.5..1 deg F.
Procedure:
_____________________
Boiling:
Distilled water, very slow boil in pyrex Erlenmeyer flask, immerse TC to middle of fluid,
Compensate for Baro pressure. CAL 100 C or 212 F.
So far within 1 deg F.

Freezing: 0 C or 32 F (not yet setup)
Dewar flask, Pyrex dim 45 mm ID 125 mm L
Add distilled water, make distilled water ice, add chopped ice,
decant most of the water, mix, allow to stab, immerse TC to middle of mix
Appreciate all comments and improvements from The CAL Mavens.
Mille mercis,
Jon
