Stepper driver vref

I’m using stepper driver stspin220 and have it soldered in where I can only access the compont side. From the picture; vref is only available on the other side. Is there a way I can probe it from the component side? What is the circled test point on the component side?
Thanks

further research shows VREF is available from the top of the potentiometer.

Problem solved.
