Hantek CC-65 AC/DC Current Probe Teardown and Testing

KlausF:
That is what I am interested in, in those variable resistors. What is adjusted with them ?

electro-56:
I was unable to get the full calibration procedure out of Hantek, but when pressed they offered this:
VR1 adjusts the scaling of the 1mV/10mA range (they called it the 100mA range), and VR2 adjusts the scaling of the 1mV/100mA range (which they called the 10A range). They also suggested squeezing the clamp jaws together while pressing the "zero" button to improve the accuracy.

What type of hall sensors are used? It seems a magnetoresistive bridge type no?

its in the OP picture, not sure what, it has SE marking on it...

harrimansat:
The other HP clamp that I have is colsed loop with inductor and hall. I don´t know how this clamp works. There´s more hall sensors in PCB?
