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 enduser 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.

700PEx Series Pressure Modules

Instruction Sheet

Introduction

The Fluke 700PEx Series Pressure Modules allow you to
measure pressure with Fluke intrinsically safe calibrators
such as the 718Ex. Read this sheet before using the
pressure modules. This instruction sheet contains
specifications and information about how to avoid damaging
the pressure modules and describes how to safely use them
in hazardous locations. Refer to your calibrator’s Users
Manual

The pressure modules measure pressure using an internal
microprocessor. They receive operating power from and
send digital information to the intrinsically safe calibrators.

• Gage pressure modules have one pressure fitting and

• Differential pressure modules have two pressure fittings

• Absolute pressure modules measure relative to a

Safety Information

In this instruction sheet a Warning identifies conditions and
actions that pose hazards to the user. A Caution identifies
conditions and actions that may damage the pressure
module or equipment under test. International symbols used
in this instruction sheet are identified later in the
section. Read the entire instruction sheet and the 700PEx
CCD (Concept Control Drawing) before using the pressure
module.

In case of doubt (due to translation and/or printing errors)
refer to the original English instruction sheet.

XW Warning

To avoid electric shock, injury, or damage to the
pressure module:

• Use the pressure module only as described

in this instruction sheet and the Fluke
700PEx CCD (Concept Control Drawing)
otherwise the protection provided by the
pressure module may be impaired.

• Inspect the pressure module before use. Do

not use it if it appears damaged.

• Check the cable for damaged insulation. Do

not use the pressure module if the cable
appears damaged.

• Never use the pressure module with the case

open. Opening the case invalidates Ex
Approval.

• This equipment is specified for use in

measurement category I (CAT I) pollution
degree 2 environments and should not be
used in CAT II, CAT III, or CAT IV
environments. Voltage transients should not
exceed 300 volts for the CAT I applications
where this product is used. Measurement
transients are defined in IEC1010-1 as 2 µs
rise time with a 50 µs duration at 50 % of the
maximum amplitude height.

• Measurement Category I (CAT I) is defined

for measurements performed on circuits not
directly connected to the mains.

Faults and Damage

If there is any reason to suspect that the safe operation of
the pressure module has been affected, it must be
immediately withdrawn from use and precautionary
measures must be taken to prevent any further use of the
pressure module in an Ex hazardous area.

XW Warning

The safety features and integrity of the pressure module
may be compromised by any of the following:

• External damage to the housing

• Internal damage to the pressure module

• Exposure to pressure loads in excess of the

maximum rated pressure

• Incorrect storage of the unit

• Damage sustained in transit

• Correct certification is illegible

• Functioning errors occur

• Permitted limitations are exceeded

• Functioning errors or obvious measurement

inaccuracies occur which prevent further
measurement by the pressure module

Safety Regulations

The use of the 700PEx pressure modules meets the
requirements of the regulations providing that the user
observes and applies the requirements as laid down in the
regulations and that incorrect use of the unit is avoided. Use
must be restricted to the specified application parameters.

Protecting Yourself from Pressure Releases

XW Warning

• To avoid injury due to the release of high

pressure, use only adapters and fittings
rated to withstand the appropriate pressure.
Ensure that all adapters and fittings are
securely connected.

• To avoid a violent release of pressure in a

pressurized system, slowly bleed off the
pressure before you attach or remove the
pressure module from the pressure line.

• When measuring the pressure of potentially

hazardous media, care must be taken to
minimize the possibility of leakage. Confirm
that all pressure connections are properly
sealed.

Avoiding Mechanical Damage

To avoid damaging the pressure modules, never apply more
than 10 ft.-lbf. of torque between the module fittings or
between the fittings and the body of the module. Figure 1
shows the correct way and incorrect ways to use a wrench
when applying torque to the pressure module fitting.
