Fluke 726 [37/80] Measuring pressure

Multifunction Process Calibrator

Using Measure Mode

Measuring Pressure

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.

Figure 12 shows the gage and differential modules.

Differential modules also work in gage mode by leaving

the low fitting open to atmosphere.

To measure pressure, attach the appropriate pressure

module for the process pressure to be tested, and

proceed as follows:

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.

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.
