either you measure it with a multi meeter (pot on the left as you look at the lazer. 'Laser pointing up at the roof, and you see the 2 pot screws and the laser') not going far passed 500
or you noob guess it.
and turn it a little bit then test it again then repeat untill it reads stuff..
you turn the screw on the left clockwize.
just did the same thing to a philips i had here. works now did not before.
i find its better to mark the screw with a marker pen, this isnt purley so you remember where it was to start it, but it lets you see how far your turning it.
Dont turn it a lot. try less than a quater turn at a time then measure the resitance. or test it (which ever way your doing it.)
As an explanation the potentiomiter restricts the power allowed to the laser. twisting it allows more power through. to much and you will kill it. to little and it wont make a diference, however its better to do to little 5 times and get it right on the 6th time if your doing it the noob way. rather than doing it to much 1ce and being unable to fix it.
