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. howie |

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

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? |
