TH2830 vs TH2832

--- Quote from: nctnico on July 04, 2023, 07:35:32 pm ---What is the spec of the LCR meter? If you want some calibration worthy standards then get parts that are 10 times better. In some designs I use 0.01% 2ppm SMT resistors as references (which are calibrated using a 6.5 digit DMM later on). These resistors are like 15 euro each from Mouser IIRC.

It claims 6 digits, .05% accuracy. Spec sheet attached. I want to get multiple test points, and extras, so I'd rather not pay $10+ per resistor (if possible). 😉

I have the calibration protocol from our ST2830, in the protocol the references are listed they used for it.

KungFuJosh:
For a 1Ω 0.1% SMD resistor my choices are 25ppm/C for $0.48, or 2ppm/C for $52.47.

I think I'm going to say 25ppm/C is good enough for me. 🤣🤣🤣

tv84:
If I were to bet, I would say luudee's files are AT - calibration and MB - settings.

The curious fact is that the mb85rc64t dump contains explicitly the "2830" reference, and he has a 2832 if I'm not mistaken.

Hmm..
Let´s hope this is the place were the open/short-calibrations are stored and nothing else.
