719PRO Users Manual Damping Turn Damping on or off with the Damping menu selection. When damping is on, the Product shows a running average from ten measurements. The Product makes approximately three indications per second. HARTTM Resistor An internal 250 Ω HART resistor can be enabled when the Product operates in the mA Measure-24 V mode. This lets a HART Communicator be connected across the mA terminals. It is not necessary to add an external resistor. Note When the HART resistor is on, the maximum load-driving capacity is 750 Ω. Pump Limits To prevent overpressure of sensitive devices, the maximum pressure (pump limit) can be set. When in this mode, use the arrow softkeys to set the maximum pressure. Initial Setup and Basic Pressure Generation The Product is supplied with a special low-volume calibration hose kit for faster pumping to pressure and quick pressure stabilization. The necessary "quick-fit" hose connectors and BSP adapter for non-NPT applications are also included. Fluke recommends that this type of hose be used to get the best performance from the Product. When the fittings are installed and the Product is connected to the unit under test (UUT), the Product is ready. Figure 3 shows a typical setup. 1. Before pressure is generated, make sure the Product is configured for the application. If necessary, review the "Calibrator Interface" section to select the correct configuration. 2. Make sure that the pressure vacuum knob is set for the correct function (+ for pressure and - for vacuum). 18 MyFlukeStore Shop for Fluke products online at: www. .com 1.888.610.7664
