Once you get the compression testor, there are some things you need to know.

You have to use a relief valve in order to release the pressure so you can see the next rotor face. This test is NOT ACCURATE either. Your compression is going to depend on alot of factors:

Heat of the motor, RPM of the starter, Accuracy of your comp gauge, etc..

What are you feeling? Lack of power?
