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 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, 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,

Personal Protective Equipment
Symbols Used in this Manual
Use of compressed gas can create an environment of propelled foreign matter. Pressure
system safety precautions apply to all ranges of pressure. Care must be taken during
testing to ensure that all hydraulic connections are properly and tightly made prior to
applying pressure. Personnel must wear eye protection to prevent injury.
Lifting and movement of heavy weights can create an environment of strain and impact
hazards. Care must be taken during testing to ensure that weight masses are lifted in a
manner that avoids over-reaching or twisting, and that the masses are not dropped.
Personnel must wear reinforced safety shoes to prevent injury.
Wear eye protection and reinforced safety shoes approved for the materials and tools
being used.
In this manual, a Warning identifies conditions and actions that pose a hazard to the user.
A Caution identifies conditions and actions that may damage the Pneumatic Deadweight
Tester or the equipment under test.
Symbols used on the DWT and in this manual are explained in Table 1-1.

Operating Principle
Deadweight Testers are the primary standard for pressure measurement. Utilizing the
well-proven Piston-Gauge system, consisting of a vertically mounted, precision lapped
Piston and Cylinder assembly, accurately calibrated weight masses (Force) are loaded on
the piston (Area), which rises freely within its cylinder. These weights balance the
upward force created by the pressure within the system.
Each weight is marked with the tester serial number, and the pressure measured when
placed on a correctly spinning and floating piston. The total pressure measured is the
summation of the weights plus the piston weight carrier assembly.

municipal waste. Go to Fluke’s website for

When the gas pressure within the system balances the combined downward force of the
piston and weights, the piston and weights will float freely and the system is in
equilibrium.
General Information
Operating & Storage Specification 1
The design of a Piston/Cylinder Unit (PCU) fitted to a deadweight tester allows for a very
small clearance gap between the piston and cylinder. This is required to allow the gas to
pass between the components, providing a lubricating film, and preventing
metal-to-metal contact.
Operating & Storage Specification
Temperature and relative humidity ranges for operation and storage of the deadweight
tester are listed in Table 1-2.

(Non-Condensing)
18 °C to 28 °C

20 % to 75 % 0 % to 90 %
Environmental Corrections
The DWT has been calibrated to the Gravity, Temperature and Air Density stated on the
certificate.
Equations and factors are given on the certificate to adjust for any variations in these
environmental conditions.
Gravity
Gravity varies greatly with geographic location, and so will the deadweight tester reading.
Due to the significant change in gravity throughout the world (0.5%), ensure that the
tester has either been manufactured to your local gravity, or that you have applied the
correction from the calibrated gravity.
Example:
Deadweight Tester calibrated gravity 980.665 cm/s²
(980.665 cm/s² is the International
Standard Gravity)
10 °C to 50 °C
50 °F to 122 °F
Gravity at site 981.235 cm/s²
Indicated Pressure 250 psi
235.981
250
xPRESSURETRUE =
665.980
psiPRESSURETRUE 1453.250=
The ability to determine the local gravity value will depend on the data available in the
country that the instrument is to be used in. Some countries have geographic/geological
survey/mapping organizations that have the data readily available. If not, the countries’
National Standards Laboratory may be able to recommend a source of suitable
information.
