dyna s units,
how can you tell what model it is if there are no labels,markings?

can they be tested?

All I can give you is http://www.dynatekuk.com" onclick="window.open(this.href);return false; they have a section with pdf's for testing systems. Is it fitted or have you just bought it in hope? The info on there might help but I'm sure dyna themselves will help out.
