TH2830 vs TH2832
hpw:
BTW:
Did someone measured a 0.1 ... 1uH SMD RF coil?
as may Hantek 1832C at 100kHz shows up only using 47uH, using an 4-pol Tweezers.. below as at lost :palm:

I'm waiting on a Mouser order with the following:
10nH
100nH
10uH
100uH
1mH
10mH

Sounds like a superhero when you spell it out. 😉
BTW- I ran the test again, this time with an official Tonghui kelvin lead fixture using a CMF 1% 100kΩ resistor. Prior to each test set, and after each firmware flashing, I let the meter warm up a minimum of 30 minutes before performing new open/short/dcr corrections.
Results:
Did you test your ST2830 with 100 kΩ with frequencies besides 100 kHz?
I have a theory that the reason I have issues with the ST firmware is that because they're older, they're likely only compatible with C6 or A6 hardware, and won't work right on C7 or A7 hardware (beyond any bugs). That would be one possible explanation why I have issues with the same version of ST2830 fw as you...assuming you are able to read 100kΩ across all the frequencies with better results.

Hi,
https://www.eevblog.com/forum/testgear/th2830-vs-th2832/msg4953937/#msg4953937
DC,100Hz, 1kHZ, 10kHz, 100kHz...
If you want other frequencies inbetween, sorry man, for the next 2weeks I couldn´t get the ST2830 for measure.. ;)
