Recently picked up a used Zonemaster II and want to calibrate as best I can to suit my LPL VCCE head. I got it used but it is in perfect condition and I have a feeling it will pay for itself in no time in saved paper.
The instruction manual that came with it has instructions for advanced calibration using your own gray scale. On the RH website there are also many other ways of calibrating it.
What I want to ask is which is the best method to use to get the most accuracy from the meter. I also have a Stouffer step wedge so I can make contacts using this if it's the better way of doing it. I see the later ones come with a step wedge and a reference tile but these didn't come with mine as it's an earlier serial number.
Will be setting it up for MG4 FB to start with.
