LIMITED WARRANTY AND LIMITATION OF LIABILITY

Each Fluke product is warranted to be free from defects in material and workmanship under normal use and service. The warranty period is
three years (one year for pump assembly) 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, contaminated, 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 non-defective 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 only 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 to obtain return authorization information, then send the
product to that service center, with a description of the difficulty, postage and insurance prepaid (FOB Destination). 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 failure was caused by neglect, misuse, contamination, alteration, accident, or abnormal condition of operation or handling,
including overvoltage failures caused by use outside the product’s specified rating, or normal wear and tear of mechanical components,
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, ARISING FROM ANY CAUSE OR 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 or other decision-maker of competent jurisdiction, such holding will not affect the validity or enforceability of any
other provision.

Introduction

XWWarning

Read Safety Information before using the
Calibrator.

The Fluke Model 718Ex 30G, 718Ex 100G, and 718Ex
300G Pressure Calibrators (hereafter called Calibrator)
can do the following:

Calibrate P/I (pressure to current) transmitters.

• Measure pressure via a 1/8-inch NPT pressure fitting

and an internal pressure sensor or via Fluke 700PEx
Series Pressure Modules.

• Measure current up to 24 mA.

• Simultaneously display pressure and current

measurements.

• Perform switch testing.

The Calibrator is for use ONLY in Ex-hazardous areas.

The Calibrator makes 5-digit pressure readings in the
following units: psi, inH
cmH2O at 4 °C, cmH2O at 20 °C, bar, mbar, kg/cm2, inHg,
and mmHg. Full-scale pressure sensor input is as follows:

• Model 718Ex 30G: 30 psi (206.85 kPa, 2.0685 bar).

OL appears at 33 psi.

• Model 718Ex 100G: 100 psi (689.5 kPa, 6.895 bar).

OL appears at 120 psi.

• Model 718EX 300G: 300 psi (2068 kPa, 20.68 bar).

OL appears at 360 psi.

The Calibrator measures pressure sensor inputs in the
units shown under Pressure Sensor Range and
Resolution.

For Pressure Modules, full-scale readings for all pressure
ranges can be made in psi, kPa, and inHg units. To avoid
display overflow, full-scale readings are limited to

O at 4 °C, inH2O at 20 °C, kPa,

718Ex 30G/100G/300G

Users Manual

1000 psi in cmH2O, mbar, and mmHg units, and 3000 psi
in inH

O units. Pressures of at least 15 psi must be

2

measured for meaningful readings in bar and kg/cm2
units.

The Calibrator is supplied with:

• a holster

• one installed 9 V alkaline battery

• one set of TL75 test leads

• one set of AC72A alligator clips

• a Control Drawing

• a CD-Rom

If the Calibrator is damaged or something is missing,
contact the place of purchase immediately. Contact a
Fluke distributor for information about accessories. See
Contacting Fluke. To order replacement parts or spares,
see Parts and Accessories.
