Page 21: Vent Port
High-Pressure Modular Controller Controller Settings (Setup Menu) The REF port can be sealed from atmosphere in most applications where the test times are relatively short. This isolates the port from pressure changes in the atmosphere and results in very stable pressure measurement and control. If the test times are relatively long, in addition to connecting the reference ports together, also routinely vent the system by placing it in VENT mode. -

Page 36: Operation
8270A/8370A Operators Manual Operation This section explains the pressure control settings of the Product. Operating Modes The product has three operating modes: Control, Measure, and Vent. Control Mode – When in Control mode, the Product actively controls pressure as defined by the Setpoint and will keep the pressure near the Setpoint per the active control mode (see Control Modes). -
Page 37: Jog Pressure
High-Pressure Modular Controller Operation Jog Pressure The Jog function can help calibrate mechanical gauges, such as a dial gauge. Use the jog wheel to change the pressure until the mechanical gauge indicates a cardinal point. The user can then read the higher resolution Calibrator to determine the actual pressure value when the mechanical gauge is indicating a cardinal point. -
Page 38: Pressure Measurement
8270A/8370A Operators Manual Pressure Measurement A visual measurement indicator on the UI (also known as the “Ready indicator”) indicates when pressure control settings are satisfied and pressure can be measured. See Table 13 for a list of measurement indicators and their definitions. -
Page 39: Dynamic Control Modes
In Figure 7, the default dynamic ready tolerance value is 0.005 % of range. On the Setup>Control Setup screen the Specify as % Range setting is used to set the control settings as % Range or pressure unit values. Fluke Calibration recommends to leave this set to Yes so the control settings scale appropriately when different ranges are active. -
Page 40: Static Control Mode
Slew Rate is a user-defined maximum pressure rate of change. The Product controls this pressure with minimum overshoot into a wide variety of external volumes at its highest slew rate. In most applications Fluke Calibration recommends that the slew rate be set at its maximum rate value. This provides the highest speed control without jeopardizing overshoot or control stability properties. -
