摘要
简单分析了几种常用的恒流供电锰铜压阻测量方法，并对这些测试方法的特点和不足进行了讨论。最后介绍一种利用数字示波器进行高保真高精度测量的方法，利用此法不仅提高了压力测量的精度，并且把小阻值锰铜压力计的测量范围向低端扩展到０．１７ＧＰａ。
Different techniques in commonly used piezoelectric manganin gauge measurement with constant current supply are briefly discussed, along with their advantages and disadvantages.A new method with higher fidelity and accuracy by using digital oscilloscope is introduced, which can improve not only the accuracy in pressure measurement, but also extend the applicable pressure range for the small resistance gauge to as low as 0 17 GPa.
