Automatic Pressure Calibrator
Measure Mode

To measure pressure:
1. Attach the applicable pressure module for the process pressure you will test as
described in the instruction sheet for the module.
W
Warning
To prevent personal injury, shut off the valve and slowly bleed off the
pressure before attaching the pressure module to the pressure line to
avoid a violent release of pressure in a pressurized system.
W
Caution
To prevent possible damage to the Product or to equipment under test:
• Never apply more than 10 lb-ft. of torque between the pressure module
fittings, or between the fittings and the body of the module.
• Always apply correct 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. See the printing on
the pressure module or the pressure module instruction sheet for the
acceptable material compatibility.
2. Connect a pressure module to the Product as shown in Figure 13 . The pressure
module shows on the display after several seconds once installed.
The Product automatically senses the pressure module attached and sets the range
accordingly.
Note
Before doing a task that sources or measures pressure, zero the Product.
3. With the pressure module highlighted in the third screen, push
D
( Zero
External ) to zero the pressure. When zeroing absolute pressure modules, enter the
current barometric pressure when the displayed value turns to yellow highlight.
4. Zero the pressure on the module. See the Instruction Sheet for the module. Modules
can have different zeroing procedures that depend on module type.
