Sourcing Pressure

The calibrator sources pressure by measuring pressure
supplied by a pump or other sources, and displaying the
pressure in the SOURCE field. Figure 20 shows how to
connect a pump to a Fluke pressure module which makes
it a calibrated source.

Many ranges and types of pressure modules are available
from Fluke. See “Accessories” near the back of this
manual. Before you use a pressure module, read its
Instruction Sheet. The modules vary in use, media, and
accuracy.

Attach the appropriate pressure module for the process
pressure to be tested.

Proceed as follows to source pressure:

Warning

To avoid a violent release of pressure in a
pressurized system, shut off the valve and
slowly bleed off the pressure before you
attach the pressure module to the pressure
line.

Caution

To avoid mechanically damaging the
pressure module, never apply more than
10 ft.-lb. (13.5 Nm) of torque between the
pressure module fittings, or between the
fittings and the body of the module. Always
apply appropriate torque between the
pressure module fitting and connecting
fittings or adapters.

To avoid damaging the pressure module from
overpressure, never apply pressure above the
rated maximum printed on the pressure
module.

To avoid damaging the pressure module from
corrosion, use it only with specified
materials. Refer to the printing on the
pressure module or the pressure module
instruction sheet for the acceptable material
compatibility.
