In this paper, we propose a new procedure for the extended calibration of charge-mode accelerometers. This procedure covers two main stages. The first one follows the general guidelines of international guides that relate to calibrating accelerometers in the frequency domain and are implemented using a weighted-least-squares method. These guidelines are modified herein for the advanced modelling of the charge-mode accelerometer. The second stage provides a new solution which is an extension of the standard calibration using the upper bound of the dynamic error (UBDE) according to the integer-square criterion and a fixed-point algorithm that enables this error to be determined. Additionally, the special functions, representing the values of the dynamic error for the predetermined ranges of the parameters associated with the mathematical model of the charge-mode accelerometer, are determined. Such functions ensure an easy and rapid execution of the second stage of calibration without conducting complicated procedures to determine the value of the UBDE.

The extended procedure proposed here enables the comparison of accelerometers with similar technical parameters, but produced by different manufacturers of measuring sensors that frequently compete with each other. In this way, we can select the accelerometer that will produce the lower value of UBDE.

在本文中，我们为电荷模式加速度计的扩展校准提出了一种新的程序。此过程涵盖两个主要阶段。第一个遵循国际指南的一般准则，该准则与在频域中校准加速度计有关，并使用加权最小二乘方法实现。在此修改了这些指导原则，以用于充电模式加速度计的高级建模。第二阶段提供了一种新的解决方案，它是根据整数平方标准使用动态误差（UBDE）的上限对标准校准进行扩展的方法，以及一种可以确定该误差的定点算法。此外，特殊功能 确定代表与充电模式加速度计的数学模型相关联的参数的预定范围的动态误差值的值。此类功能可确保轻松，快速地执行第二阶段的校准，而无需执行复杂的过程即可确定UBDE的值。

此处提出的扩展程序可以比较具有类似技术参数的加速度计，但是这些加速度计是由经常相互竞争的测量传感器的不同制造商生产的。这样，我们可以选择将产生较低UBDE值的加速度计。
