Measuring Pressure
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.
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
Proceed as follows to measure 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.
