Introduction
The Fluke 700PDX Series Pressure Modules measure
positive and negative pressure. The 700PVX modules
measure vacuum. The 700PDX modules work with the Fluke
700 Series Documenting Process Calibrators. The 700PVX
modules work only with the 740 Series Calibrators. Read this
sheet before you use the pressure module. This sheet
contains specifications and information about how to avoid
damaging the pressure module. See the calibrator’s Users
Manual for operating instructions.
Note
If you are using a Fluke-701 or Fluke-702, software
V1.3 or higher is required. See specification
footnote 1.
The pressure module measures pressure or vacuum using
an internal microprocessor. It receives operating power from
and sends digital information to the calibrator.
Gage pressure modules have one pressure fitting and
measure pressure with respect to atmospheric pressure.
Differential pressure modules have two pressure fittings and
measure the difference between the applied pressure on the
high fitting versus the low fitting. A differential pressure
module functions like a gage module when the low fitting is
open.

Avoiding Mechanical Damage
To avoid damaging the pressure module, never apply more
than 10 ft.-lbs. 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. Figure 1 shows the
correct way and incorrect ways to use a wrench when
applying torque to the pressure module fitting.
Protecting Yourself from Pressure Releases
To avoid a violent release of pressure in a pressurized
system, shut off the isolation valve and slowly bleed off the
pressure before you attach or remove the pressure module
from the pressure line.
Avoiding Overpressure Damage
Applying pressure in excess of the BURST PRESSURE
specified on the pressure module can destroy the pressure
module. Burst pressure is 3X full scale.

Avoiding Corrosion Damage
To avoid damaging the pressure module from corrosion, use it
only with specified media as shown below:
•
Isolated: any medium that is compatible with type 316
stainless steel on the high side. Use dry, noncorrosive
gasses only on the low side.
Nonisolated: dry, noncorrosive gasses only.
•
Recommended Measurement Technique
For best results, it is recommended that the module be
pressurized to full scale and then vented to zero pressure
(atmosphere) prior to zeroing and making measurements.
Note
Low range pressure modules may be sensitive to
gravity. For best results, pressure modules 30
psi and below should be held at the same
physical orientation from the time they are
zeroed until the measurement is complete.
Pressure Calibration Kit
The Fluke-700PCK Pressure Calibration Kit makes it possible
to calibrate pressure modules at ambient temperature with a
precision pressure calibrator or dead weight tester at least 4X
better than the module specification. A 386 or better PC and
Windows
®
3.1 are required. The kit is an optional accessory
available from your distributor or Fluke.
Performance Test
If you need to check that the pressure module meets its
accuracy specification, use a dead weight tester or suitable
pressure calibrator. The accuracy of the dead weight tester or
pressure calibrator should be at least 4X better than the
module’s pressure specification. Proceed as follows to verify
that a pressure module is operating within specification:
1.
Read the pressure value with no externally applied
pressure to make sure the 0% of scale is correct. When
reading the pressure with a 700 Series calibrator, press
the ZERO key to remove any zero offset.
Note
If you are using a Fluke-701 or Fluke-702, the
pressure ZERO function is available only with V1.3 or
higher software. Contact your Fluke Service Center
for upgrade of earlier calibrators.
2.
3.
4.
Connect the pressure module to a dead weight tester.
Choose pressure test values that give approximately 20%
of full span steps.
Set the dead weight tester to each of these pressures and
verify that each reading is within the specification in
Table 1. Percent of full span is calculated as follows:
100% x (reading - dead weight tester setting) / (top of
span - bottom of span).
If temperature sensitivity is of concern, repeat steps 1
through 4 at various controlled temperatures.
