they are useful tools,but there is no standard settings,each brand measures a little different than the other,making them somewhat confusing to use,but these charts may help you sort it out....bonbon

y is it that when i get my reading to 500ppm with my nutrients i put the acid in to bring the ph down and the ppm reading goes up to 1200-1300? it makes it really confusing when topping up a 20 litre tank.
