Hot to check clutch disengagement measurement with blow proof bellhousing

Do i need to check it with pedal all the way to the floor? What would be the best process to adjust it. Im mechanically inclined, just want to make sure i do it the proper way
clutch needs to be all way to floor, it takes a helper to make it work. once measured, release pedal, adjust clutch rod in or out, depends which way you need to go, out will give you more gap. lengthens the rod. also free play is required. at top .
