Pressure Specifications
[1] The minimum negative pressure limit is given based on the atmospheric pressure value of 1bar.
[2] Precision: the error components include linearity, hysteresis, repeatability, resolution, and temperature compensation.
[3] Accuracy: the error components include linearity, hysteresis, repeatability, resolution, reference standard measurement uncertainty, annual drift,
temperature compensation, K=2.
[4] In order to achieve 0.001% FS control stability, some additional stabilization time at the desired pressure may be needed depending on the conguration
and pressure level.
[5] The air pressure is tested under an external load volume 50 ml, 20% step, and the time to reach 0.005%FS stability,for 0.001%FS stability, needing
more time.
[6] The air pressure is tested under an external load volume 50 ml, 10% step, and the time to reach 0.005%FS stability,for 0.001%FS stability, needing
more time.
[7] After the reference atmospheric pressure module is installed, users can select gauge or absolute pressure.
[8] Gas refers to clean and dry nitrogen or air.
[9] In order to achieve the best control effect, the air source pressure should be adjusted to about 110% of the maximum range of the internal pressure
control module or 1bar, whichever is greater.
[10] In order to prevent the inlet pressure of the air source from exceeding the safety limit, it is recommended to install a suitable pressure safety valve at
the outlet of the air source.
[11] All pressure ports are installed with 40~100 μm lters.
