Precision: the error components include linearity, hysteresis, repeatability, resolution, and temperature compensation.  Accuracy: the error components include linearity, hysteresis, repeatability, resolution, reference standard measurement uncertainty, annual drift, temperature compensation, K=2.  In order to achieve 0.001% FS control stability, some additional stabilization time at the desired pressure may be needed depending on the configuration and pressure level.  The air pressure is tested under an external load volume 50 ml, 20% step, and the time to reach 0.005% FS stability.  After the reference atmospheric pressure module is installed, users can select gauge or absolute pressure.  Gas refers to clean and dry nitrogen or air.  In order to achieve the best control effect, the pump source pressure should be adjusted to about 110% of the maximum range of the internal pressure control module, or 1 bar, whichever is greater.  In order to prevent the inlet pressure of the air source from exceeding the safety limit, it is reccomnded to install a suitable pressure safety valve at the outlet of the air source.  All pressure ports are installed with 40 ~ 100 μm filters.
