With load on the back of the 'bike so the belt is at it's tightest point, then it should turn through 90 degrees,more and it's too loose less too tight.

Once You have the tension set as the above you can work out how to measure it in an easier way. You could try topped out and measure it from a fixed point on the swingarm to the belt pushed down. Much easier to do.
