Caution
To avoid mechanically damaging the pressure module, never apply
more than 10 ft-lb. of torque between the pressure module fittings, or
between the fittings an the body of the module.
To avoid damaging the pressure module from overpressure, never
apply pressure above the rated maximum printed on the module.
To avoid damaging the pressure module from corrosion, use it only
with specified materials. Refer to the pressure module
documentation for material compatibility.
To measure pressure, follow these steps:
1. Connect the pressure module to the calibrator as shown in
Figure 9.
The calibrator can measure pressure on both the upper and the
lower display. This makes it possible to measure pressure in two
different units at the same time.
2. Switch to either upper or lower display from the Main Menu.
3. Select [PRESSURE] from the primary parameters.
4. Select the desired measuring unit.
5. Zero the pressure module. The zero function on the calibrator
can be found in the pressure zeroing menu.

3.4-1 Zeroing with Absolute Pressure Modules.
To zero, adjust the calibrator to read a known pressure, such as
barometric pressure.
