I have recently bought a laser level but it doesn't come with a manual.
I'm having a few troubles sometimes calibrating the thing as there are three water levels to be set: one for the tripod, another for the base and the third for the level itself. The level on the base is particularly tricky because the base itself has to be rotated (useful feature for many jobs). Has anyone found a trusted and quick way of calibrating optical instruments using three adjustable screws?
Any hint would be appreciated.
