Stepper Driver A4988 /setting current limit issue/

Hi,

I would like to ask how can I set current limit on my A4988.
I tried to follow this video Setting the Current Limit on Pololu Stepper Motor Driver Carriers - YouTube but I dont have
white circle and have no idea where I should measure voltage.

Thanks

The Pololu A4988 web page has a good explanation.

OK, one lead of your DVM is connected to the VMOT, motor voltage, pin. Where is the other DVM pin connected? And when you get time, draw a schematic of how you have all this wired up. Sus =pect there is an error.
