I adjust for harder braking until it locks up the trailer wheels when doing a hard brake at low speed(20-25mph). Usually at the farm on a dirt road. Then I back it off until it no longer locks up the wheel.
This is how I've done all the different ones I've had over the years, mainly because that's what the manuals all have said was the proper way. My Hard Brake was through the manual slide on the brake controller, not through the pedal. I generally end up lowering it slightly from the first setting that doesn't lock the brakes so it feels like my truck normally does when I'm breaking and not using the trailer to slow me more slowly than normal.
Here's a link to the basics. This is the same controller I used in my last truck that didn't have the controller built in it. I use the same technique to set the controller that came with my truck and it's always worked fine.
