最简捷的方法就是测量芯片的电源引脚与地之间的电阻。
The most simple and quickest way is to pin the power measurement chip with the resistor between.
数字式电压表在测量低于20欧姆的电阻时﹐会因为引脚的电阻而使测量不准确。除非它是一个四线欧姆表。
DVM is not accurate in measuring resistance below 20 ohm due to the lead resistance, unless it is a 4 wired ohm meter.
加速度计的敏感元及测量专用芯片（ASIC） 集成在DIL 塑料封装内，其引脚可用于表面安装和回流焊接。
The sensing element and the measuring ASIC are assembled in a dual-in-line (DIL) plastic package with pins for surface mount and re-flow soldering.
