Hello,
i am using the 12-Channel On-Board 95% Accuracy AC Current Monitor with I2C Interface to read some current values from my home wiring. It’ a little bit older one but now I want to use it productive. I have done some testing and I am getting very bad results. As an example:
Starting a microwave the real messuament is round about 3,4a. The unmodified sensor tells me, that I have a value from 1,5a. Next I have calibrated the sensor to show the correct value from nearly 3,4a. That’s fine but next, the microwave will switch between 3,4a and 0,1a because of selected wattage. But now the sensor shows 0,5a instead of 0,1a. If i will recalibrate now to show the correct value - the messuarement of 3,4a will be wrong.
So what’s wrong here? I can’t meassure correct values.
Thanks,
