I have CT with coil ratio 2000/1. My vref is 3.3V and burden resistor is around 11ohm.
Test one light bulb – the current is around 2Amp and device reads around 2Amp as well ( i modified the calibration value).
when i change the load to a heater which consumes somewhere around 15A, the device reads 10-11Amp.
now i change the load to 70Amp load and the CT reads somewhere around 33-35Amp.
The CT i have can read a max 200Amp.
any idea why it wont read linear ?
Thanks in advance.
