Pressure Specifications Specification ADT793 Pressure Range 0 to 15,000 psi (1,000 Bar) Precision  0.008% RD or 0.007% FS or 0.01% FS Accuracy  0.01% RD or 0.01% FS or 0.02% FS Control Stability  < 0.005%FS, typically 0.003%FS Control Response Time  < 30 Seconds Pressure Type  Gauge, absolute Internal Pressure Control Modules 1 External Pressure Control Modules 1 Max Pressure Range of Internal Module 0~15,000 psi (0~1,000 Bar) Min Pressure Range of Internal Module 0~3,000 psi (0~200 Bar) Min Range of External Module 0~1,000 psi (0~70 Bar) Range Switching Mode  Fixed, auto Pump Source Type  Built-in hydraulic pump, no external pressure source required. Control Mode Fast, standard, custom Maximum Overshoot < 1%FS Maximum Load Volume <10,000 psi: Max: 80 ml, 50 ml recommend, 10,000~15,000 psi:Max: 60 ml, 35 ml recommend Contamination Prevention System (CPS) Optional Pressure Port 1/4 BSP M Built-in Reservoir Volume 800 mL External Reservoir Extension Optional Port Filter  Optional Media Diethylhexyl Sebacate or deionized water  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 0.003% FS control stability, some additional stabilization time at the desired pressure may be needed depending on the configuration and pressure level.  The hydraulic pressure is tested under an external load volume 10 ml, 20% step, and the time to reach 0.005% stability.  Absolute pressure measurements require the optional barometer pressure module (ADT151-BP) to be installed.  Does not support automatic range switching between the internal control pressure module and the external control pressure module.  Liquid refers to Diethylhexyl Sebacate or deionized water.  All pressure ports are installed with 40~100 μm filters.
