Dang you had my hopes up that they might have fixed it...

Still nothing from the vendor. I think I give it about 10% chance they actually do anything about it.

Started conversation with the manufacturer :(

Recalibrated it again

995k measured directly in ET432

100 = 992.9
1k = 993.4
10k = 993.4
40k = 991.9
100k = 964.7 %(

Still chatting with manufactorer's EE

He has some plot. Gave me video of 1694 RLC Bridge.
It show's the same fall at 100+kHz for carbon resistor

Carbon resistors it is expected behavior that the resistance changes with frequency. You have to test with a precision film resistors that do not change resistance within the 100khz frequency.
