Dear All,
We have installed our fifth Shelly 3EM to one of our machine. We are experiencing huge difference in the measured current value compared to our calibrated Fluke current clamp. The calibrated, real current value is almost twice compared to what the shelly shows (96A vs 50A).

There is definitely something wrong with the measurement. Can anyone help what is wrong?
I tried different firmwares all gave the same result.
