Hello Walter, thank you for your post,
some answers:
1) Am I understanding you correctly that the test strip holder passes through the machine from the left to the right or right to the left?
yes

1.1)If this is true could you base your saturation curve on the number of passes through the machine at the same speed and not time?
it could be possible, it what discussed as one possiblity


1.2)What is the speed of the conveyor?
at first point, it's 10m/min


2) You have 3 turbines or wheels, can you turn them on and off independently?
This is something I ask since a lots of time, for the moment everything run at the same time

3) Does each wheel peen the same test strip location?
No, one plaquette for each turbine, but, everything run a the same time, so result is a bit a mix of everything

4) At each arc height reading what would you estimate the coverage percentage to be on the test strip?
coverage is 100% since the first passage
