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, 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 7526A Precision Process Calibrator (the “Product” or “Calibrator”) is an
accurate, full-featured temperature, pressure, and DC calibrator. The Calibrator is meant
for research and development, manufacturing, and calibration lab procedures. The
Product operation is easy and you will quickly understand its operations and features.

Some time-saving features let you:

• Save, recall, and automatically move through setpoints for each output range

• Record user-defined RTD curves

• Remotely interface with the Product
For complete use instructions, see the Users Manual found on the product CD-ROM.

Safety Information

A Warning identifies conditions and procedures that are dangerous to the user; A
Caution identifies conditions and procedures that could cause Product damage,

equipment under test damage, or permanent loss of data.

Warnings

To prevent possible electrical shock, fire, or personal injury:

• Read all safety Information before you use the Product.

• Carefully read all instructions.

• Use the Product only as specified, or the protection

supplied by the Product can be compromised.

• Use this Product indoors only.

• Examine the case before you use the Product. Look for

cracks or missing plastic. Carefully look at the insulation

around the terminals.

• Use only the mains power cord and connector approved for
the voltage and plug configuration in your country and rated
for the Product.

• Replace the mains power cord if the insulation is damaged
or if the insulation shows signs of wear.

• Make sure the ground conductor in the mains power cord is
connected to a protective earth ground. Disruption of the
protective earth could put voltage on the chassis that could
cause death.

• Do not put the Product where access to the mains power
cord is blocked.

• Do not touch voltages > 30 V ac rms, 42 V ac peak, or 60 V
dc.

• Use only cables with correct voltage ratings.

• Do not apply more than the rated voltage, between the

terminals or between each terminal and earth ground.

• Do not use the Product around explosive gas, vapor, or in
damp or wet environments.

• Remove all probes, test leads, and accessories that are not
necessary for the measurement.

• Do not use the Product if it operates incorrectly.

• Do not use and disable the Product if it is damaged.

Function Keys

This key is used for multiple functions. In normal operation
it is used to move through the 50 mA, 10 V and 100 V
ranges.

If held for 3 seconds it will change the Product into or out of
switchtest mode. In switchtest recall mode it will move
through the stored switch test data.

When you use 24 mA mode to verify a two-wire loop
powered transmitter, disconnect it from its wires and push
L. This turns on an internal 24 V power supply in series
with the current measurement circuit. Push the key again
to turn off the 24 V supply. In all switch test modes, push
this key to start or stop a test.

When you use 50 mA mode to verify a HART configuration
device, push this key to turn on an internal 250  resistor
in series. Push the key again to turn off the resistor. Note
that when you turn on this resistor, the maximum load­driving functionality drops from 1000  at 20 mA to 750 
