自动标准压力发生器(以下简称发生器)性能的一个重要指标是准确度。当发生器处于动态控制模式及使用面板显示时需要考虑附加控制准确度。本文通过对PACE6000系列的发生器进行比对实验，以活塞式压力计为标准器，高准确度数字压力计为参考对象，得出了其控制准确度，最后给出了以0.01级数字压力发生器为标准器、0.05级数字压力计示值误差的测量不确定度分析，其内置压力传感器的最大允许误差须为依0.008%。

An additional uncertainty of pressure generators can be introduced to account for control precision. This additional precision is on-ly needed when the controls are in dynamic mode and the operator is using the front panel to display. Herein a calculation method of control preci-sion is displayed for PACE6000 serials pressure generators. It is assumed that a piston gauge is used as standard while a high-precision digital pressure gauge is applied as reference, and when 0.01-class pressure calibrator is used as standard, the uncertainty analysis of 0.05-class digital pressure gauge is shown, and the MPEV ( maximum permissible error value) of inlet-pressure transducer must be ±0.008%.
