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 18 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”. Before using 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:
W
Warning
To avoid a violent release of pressure in a
pressurized system, shut off the valve and
slowly bleed off the pressure before attaching
the pressure module to the pressure line.
W
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.
•
Never apply pressure above the rated
maximum printed on the pressure
module.
•
Use the pressure module only with
specified materials. Refer to the printing
on the pressure module or the pressure
module instruction sheet for the
acceptable material compatibility.
