Limited Warranty
Each Fluke product is warranted to be free from defects in material and
workmanship under normal use and service. The warranty period is one year
and begins on the date of shipment. Parts, product repairs and services are
warranted for 90 days. This warranty extends only to the original buyer or end
user customer of a Fluke authorized reseller, and does not apply to fuses,
disposable batteries or to any product which, in Fluke’s opinion, has been
misused, altered, neglected or damaged by accident or abnormal conditions of
operation or handling. Fluke warrants that software will operate substantially in
accordance with its functional specifications for 90 days and that it has been
properly recorded on nondefective media. Fluke does not warrant that software
will be error free or operate without interruption.
Fluke authorized resellers shall extend this warranty on new and unused
products to end user customers only but have no authority to extend a greater or
different warranty on behalf of Fluke. Warranty support is available if product is
purchased through a Fluke authorized sales outlet or Buyer has paid the
applicable international price. Fluke reserves the right to invoice Buyer for
importation costs of repair/replacement parts when product purchased in one
country is submitted for repair in another country.
Fluke’s warranty obligation is limited, at Fluke’s option, to refund of the purchase
price, free of charge repair, or replacement of a defective product which is
returned to a Fluke authorized service center within the warranty period.
To obtain warranty service, contact your nearest Fluke authorized service center
or send the product, with a description of the difficulty, postage and insurance
prepaid (FOB Destination), to the nearest Fluke authorized service center. Fluke
assumes no risk for damage in transit. Following warranty repair, the product
will be returned to Buyer, transportation prepaid (FOB Destination). If Fluke
determines that the failure was caused by misuse, alteration, accident or
abnormal condition of operation or handling, Fluke will provide an estimate of
repair costs and obtain authorization before commencing the work.
Following repair, the product will be returned to the Buyer transportation prepaid
and the Buyer will be billed for the repair and return transportation charges (FOB
Shipping Point).
THIS WARRANTY IS BUYER’S SOLE AND EXCLUSIVE REMEDY AND IS IN
LIEU OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING
BUT NOT LIMITED TO ANY IMPLIED WARRANTY OF MERCHANTABILITY
OR FITNESS FOR A PARTICULAR PURPOSE. FLUKE SHALL NOT BE
LIABLE FOR ANY SPECIAL, INDIRECT, INCIDENTAL OR CONSEQUENTIAL
DAMAGES OR LOSSES, INCLUDING LOSS OF DATA, WHETHER ARISING
FROM BREACH OF WARRANTY OR BASED ON CONTRACT, TORT,
RELIANCE OR ANY OTHER THEORY.
Since some countries or states do not allow limitation of the term of an implied
warranty, or exclusion or limitation of incidental or consequential damages, the
limitations and exclusions of this warranty may not apply to every buyer. If any
provision of this Warranty is held invalid or unenforceable by a court of
competent jurisdiction, such holding will not affect the validity or enforceability of
any other provision.
700PAx Series Absolute
Pressure Modules
Instruction Sheet
Introduction
Fluke Models 700PAx Series Pressure Modules allow you to
measure absolute pressure with the Fluke 740 Series
Documenting Process Calibrators. The modules have one
fitting and measure pressure with respect to an absolute
vacuum.
Read this sheet before you use the pressure module. This
sheet contains specifications and information about how to
avoid damaging the pressure module. This instruction sheet
assumes that you know how to use the 740 Series
Documenting Process Calibrator. (Refer to the Users Manual
if necessary.)
Note
These modules are not specified for use with a
Model 701 or 702 Calibrator.
The pressure module measures pressure using an internal
microprocessor. It receives operating power from and sends
digital information to the calibrator.
Box Contents
Pressure module, one 1/4 NPT to 1/4 ISO metric adapter,
strap, and instruction sheet.
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.
In Case of Difficulty
For service or calibration, call your nearest authorized Fluke
Service Center. To locate an authorized service center, visit

Avoiding Overpressure Damage
Applying pressure in excess of the BURST PRESSURE
specified on the pressure module can destroy the pressure
module. Burst pressure is atmosphere plus 3X full scale in
absolute units.
Avoiding Mechanical Damage
To avoid damaging the pressure module, never apply more
than 10 ft.-lb. of torque between the pressure module fitting
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 and incorrect ways
to use a wrench when applying torque to the pressure
module fitting.

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. A vacuum
source is required. The accuracy of the dead weight tester or
pressure calibrator must be significantly better than the
pressure module specification. A 386 or better PC and
Windows® 3.1 or later are required. The kit is an optional
accessory available from your distributor or from Fluke.
Figure 1.
Avoiding Corrosion Damage
To avoid damaging the pressure module from corrosion, use
it only with media that are compatible with type 316 stainless
steel.
Performance Test
If you need to check that the pressure module meets its
accuracy specification, use a dead weight tester. The
accuracy of the dead weight tester should be significantly
better than the pressure module specification. Proceed as
follows to verify that a pressure module is operating within
specification:
1.
2.
3.
Connect the pressure module to a dead weight tester.
Apply a vacuum and zero as described earlier under
“Zeroing.”
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 the 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.
If temperature sensitivity is of concern, repeat steps 1
through 3 at various controlled temperatures.
Recommended Measurement Technique
For best results, it is recommended that the module be
pressurized to full scale and then vented to atmospheric
pressure prior to zeroing and making measurements with the
740 Series calibrator.
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.
Zeroing
Recommended procedure:
1. Connect the pressure module to the 740 Series
calibrator and select the measure pressure function.
2.
3.
Apply a vacuum to achieve a pressure below the rated
resolution of the pressure module being zeroed.
Press the [ZERO] key, and enter 0.0 as the applied
pressure.
