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.

Gage and Differential Pressure Modules 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. 27
