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.

HART
Resistor
An internal 250
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.
When the HART resistor is on, the maximum
load-driving capacity is 750
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).
