hello all,

       how to measure hall angle offset in mce wizard.  I am using 3 digital hall sensors, each displacement by a 120-degree electrical angle.  my scope has two channels both have only one reference point. then how do I measure the UV line back emf, hall sensor1 waveform? please guide me,  without the hall sensor it is working fine,

Hi @Kaleeswaran ,

Please refer to the below image for the measurement of the Hall angle offset. And for more information please refer to section 2.8.6 of the Functional reference manual.

As you said you have 2-channel oscilloscopes with one reference point, you can measure the line-line back EMF and Hall signal shown in the image by using two isolated probes or one differential probe for the line-line back EMF, and a passive probe for the Hall signal measurement.

Best Regards,
