I agree with benjiboy, I understand that the OP is asking for the specific usage of the 758 for the Zone system. But like I have said, if you understand the Zone system well, a reading of the manual for the meter will tell you how you want to use it. Once you have good understanding of the Zone system and how each function of the meter works, you can then devise for yourself a procedure to use it. Each person would work differenrently.
