On page 24 of the Kapex 120 manual, using the 4 cut method of testing angles. A statement says "The factory calibration threshold is ± 0.16°" .
My quandary is this their setting limit for one or all four of the angles ie ( 0.16° or 0.04° each). Being a German company they know what they mean but it doesn't come over like that, 0.04° of a degree that is one hell of a tolerance.
As the formulae is for four cuts I assume 0.16° is the correct, but I wouldn't put a bet on it.
