(moved) I knocked off my Watameter!

[teo]

Hi,
I posted before in MF forum because I hoped to use the watameter with a zeiss 6x6 folding camera, but maybe it's better here, since the telemeter is a generic tool.
Today I've just bought a Watameter rangefinder, it was perfectly accurate, then... I fiddled too much with it, trying to see its limits and now it's totally off... 😱
And, to make things worse, I found that the "screw" (it's a little knob) inside the big knob can be unscrewed. It has a spring, and a ball inside. I tought It was meant to adjust the metering. Tried re-screwing in at infinite, and then tried again at min. distance (30cm). Now it's worse than ever... :bang:

It had the reading not only on the knob, but also in the viewfinder: now the knob is totally off scale, and the finder doesn't show anymore the metering 😡

I googled a bit in search of a manual, can you give me some hints? Sorry for the lameness, it goes all wrong these days....:bang:

(SOLVED)
I decided to dismember the rangefinder, and understood a thing: the scale on the external knob is only 30-50cm, the numbers in the finder instead go to infinite. The little knob screw IS used to adjust, and I did it for the 30-50 knob scale.
The inside numbers instead are a harder problem: the're printed on a plastic film, simply glued inside the knob. Simply the glue dried and the film was loose.
I'm going to re-glue it, after finding the right position for correct metering. However it's going to be a critic task to glue it precisely...

Morale: better buy a meter with only an external scale, like the Telex or the original Watameter (not super) if you want a robust one.
