Hi, I have a question. Can I measure range to each obstacle from the edges of the table after placing obstacles, but before placing ships? Just to know precisely where they are?

No.

You can only measure range when the rules indicate you can measure range, and that is not one of those times.

You could, technically, insist however at R2 ruler being placed by the edge of the board and R1 being placed by nearby obstacles each time one is being placed during setup, either by you or your opponent, even if it's being laid down in an obviously legal position. There's no rule whatsoever which would support the "you can see it's far enough" measurements.

By sticking to that during setup you might be able to extrapolate the useful ranges on the battlefield.

Cheers.

There would be a risk of your opponent calling you for stalling / slow play if you were too pedantic about this, though. Do so at your own risk.

Also, along that same line, you cannot measure beyond range 1 when placing your ships for anything.

Players can use only their range rulers and maneuver templates within range 1 of that player’s edge to help them set up formations during deployment.

This is, of course, tournament level rules, and in casual games, your opponent can overrule it. But this disallows players from sticking their full range ruler out in the play area at range 3 from the edge for alignment help.
