Status so far¶
It has taken some time, but here is the result of driving the C-field with the Fluke 732 and a Vishay Z201 2k5 resistor:
To be honest, I’m not 100% sure exactly how well this plot reflects the actual difference, because there is still a lot of temperature dependency left;
My lab’s temperature is not well controlled this part of year where the dehumidifier struffles with wet autumn(-ish) weather.
However, I can say with pretty good certainty that the temperature has not been twice as stable this week, so there is no doubt that there is an improvement.
Next experiment is probably to try to collect some minutes of the signal going into the A9 integrator and see what can be learned from it.
