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 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
The Fluke 729 Pro Automatic Pressure Calibrators (the Product) are portable field
pressure calibration tools for lab or field use. This battery-operated product performs
automatic pressure calibration of transmitters, pressure switches, and gauges. The
automatic functions are done by the Product or by downloaded tasks from calibration-
management software (CMS). The Product also supplies basic HART®communicator
functions when used with HART-capable transmitters.
Product key features and benefits include:
• Automatic pressure calibration of transmitters, pressure switches, and pressure
gauges.
• Source and measure pressure to test and calibrate pressure sensors, transmitters,
and other pressure instruments.
• Source and simulate milliamp signals while measuring pressure for testing current to
pressure converters (I/P).
• HART (Highway Addressable Remote Transducer) communication to configure and
perform trim on HART smart-pressure transmitters.
• Provides Loop Power and simultaneously measures mA output from a connected
device.
• Measures pressure with all Fluke-750P Series pressure modules.
• Document automated as-found/as-left procedures to satisfy quality regulations or
audits with DPCTrack2 software.
• Advanced features like auto step and auto ramp allow tests of devices automatically.
• The pressure switch test automatically ramps pressure up and down across expected
switch trip setting to calibrate pressure switches.
• Interchangeable Pressure Measurement Modules

The display can also show different configurations:
Typically, the display does shows two functions, see Figure 1.
See Triple-Function Display for more information.
• The upper display for the internal pressure has these functions:
◦VENT
◦SOURCE
◦MEASURE
• The lower display shows these functions:
◦Measure Current
◦Source Current
◦Simulate Current
◦Measure VDC
◦Switch

The screen has two sections:
The upper display shows the internal pressure controller status and includes:
•Mode: Measure, Source, and Vent
•Pressure Value: Current measured pressure and unit
•Status: Shows nothing in measure mode, NOT READY, STABLE in source mode,
and VENTING, VENTED in vent mode.
•Setpoint: Current setpoint for source function.
•Step Size: The step size when B (Step Up) and C (Step Down) are
pushed when sourcing pressure.
The lower display shows the electrical status and includes:
•Mode: Measure Current, Source Current, Simulate Current, Measure V dc, and
Switch.
•Reading: Current reading from measure functions or setpoint for source functions.
•Switch State: Shows the pressure reading when the switch contacts open and close.

Triple-Function Display
When the third function (RTD, External Pressure Module, HART Transmitter, or FC
secondary device) is connected, the Product changes to triple-function display
automatically. In the subsequent triple-function display, the original bottom half of the
display is divided into two parts:
• The left display continues to show the electrical measurement display.
• The right display shows the model name, reading, and units from the selected third
function. See Figure 2. The figure shows a transmitter device (3051C).
When more than one third function is available, use the arrow keys to highlight the
device (in yellow) in the right display. Then use the softkeys to select the device to show.
Figure 2. Triple-Function Display
RTD Connection
The display can show RTD temperature measurements in the selected unit (C/F) as the
third-function. When the temperature unit field highlights, push the softkey to toggle the
temperature setting. The Oreading shows.
Note
The Product supports PT100-385 RTD only.

Pressure Module Connection
The Product automatically detects external pressure module installation or removal.
Move the cursor to the unit type and push E to configure the pressure-unit type (it can
be different from the pressure unit of internal pressure). Change the unit type of the
internal pressure to automatically change the unit type of the pressure module.
Figure 3shows a pressure module as the third function.
• When you plug in an external pressure module, the pressure-unit type defaults to the
internal pressure unit type.
• When you remove or install an external pressure module, the zero offset resets.
