Method for determining reference value and method for setting reference value

The invention relates to a method for determining, in particular for calculating, a reference value of an oscillator in a timepiece movement, comprising at least the following steps: oscillating the oscillator relative to a frame of the timepiece movement; -positioning the timepiece movement in a plurality of predetermined positions with respect to the direction of gravity of the earth; determining, for each position, a piece of data relating to the coordinate system of the oscillator; and-determining a value of a coordinate system of the oscillator, in particular a directed value of the coordinate system, using the data from the previous step and/or defining a function of the directed value of the coordinate system as a function of the position of the timepiece movement relative to the direction of gravity of the earth. 本发明涉及一种用于确定、特别是用于计算钟表机芯中的振荡器的参考值的方法，该方法至少包括以下步骤：-使振荡器相对于钟表机芯的框架振荡；-将钟表机芯定位在相对于地球重力方向的多个预定位置；-对于每个位置，确定与振荡器的坐标系有关的一段数据；以及-使用来自前一个步骤的数据确定振荡器的坐标系的值、特别是坐标系的有向值和/或根据钟表机芯相对于地球重力方向的位置定义坐标系的有向值的函数。
