Users Manual

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:

WWarning

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.

WCaution

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.
