Kaput,
I have an Ittok and just looked at the Ekos online. They look very similar. You set the verticle tracking force dial to zero and then balance the arm with the couterweight so that it floats over the record being level. You then dial in your tracking force. My Ittok has an o ring inside for a friction fit and simply slides front to back. Your Ekos is likely this way also but some tonearms use a set screw on the counterweight.
I don't think the tracking force dial is as accurate as a scale but it will get you close and you can dial it in by ear or buy a scale later.
