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.

Safety Information
This Calibrator complies with IEC publication 1010-1 (1992-1), Safety Requirements for
Electrical Measuring, Control and Laboratory Equipment, and ANSI/ISA-S82.01-1994,
and CAN/CSA-C22.2 No. 1010.1-92. This manual contains information, warnings, and
cautions that must be followed to ensure safe operation and to maintain the Calibrator in
a safe condition. Use of this Calibrator in a manner not specified herein may impair the
protection provided by the Calibrator.
This Calibrator is designed for IEC 1010-1 Installation Category II use. It is not designed
for connection to circuits rated over 4800 VA.
Warning statements identify conditions or practices that could result in personal injury
or loss of life.
Caution statements identify conditions or practices that could result in damage to
equipment.
SYMBOLS MARKED ON THE CALIBRATOR
WARNING Risk of electric shock. Refer to the manual (see the Index for
references).
GROUND Ground terminal to chassis (earth).
Attention Refer to the manual (see the Index for references). This
symbol indicates that information about usage of a feature is contained in
the manual.
AC POWER SOURCE
The Calibrator is intended to operate from an ac power source that will not apply more
than 264V ac rms between the supply conductors or between either supply conductor
and ground. A protective ground connection by way of the grounding conductor in the
power cord is required for safe operation.
USE THE PROPER FUSE
To avoid fire hazard, use only the specified replacement fuse:
•For 100 V or 120 V operation, use a 5A/250V time delay fuse (Fluke PN 109215).
•For 220 V or 240 V operation, use a 2.5A/250V time delay fuse (Fluke PN 851931).
GROUNDINGTHE CALIBRATOR
The Calibrator uses controlled overvoltage techniques that require the Calibrator to be
grounded whenever normal mode or common mode ac voltages or transient voltages
may occur. The enclosure must be grounded through the grounding conductor of the
power cord, or through the rear panel CHASSIS GROUND binding post.

USE THE PROPER POWER CORD
Use only the power cord and connector appropriate for the voltage and plug
configuration in your country.
Use only a power cord that is in good condition.
Refer power cord and connector changes to qualified service personnel.
DONOT OPERATE IN EXPLOSIVE ATMOSPHERES
To avoid explosion, do not operate the Calibrator in an atmosphere of explosive gas.
CHECK INSULATIONRATINGS
Verify that the voltage applied to the unit under test does not exceed the insulation
rating of the UUT and the interconnecting cables.
DONOT REMOVE COVER DURINGOPERATION
To avoid personal injury or death, do not remove the Calibrator cover without first
removing the power source connected to the rear panel. Do not operate the Calibrator
without the cover properly installed. Normal calibration is accomplished with the cover
closed. Access procedures and the warnings for such procedures are contained in the
Service Manual. Service procedures are for qualified service personnel only.
DO NOTATTEMPTTO OPERATEIFPROTECTIONMAYBEIMPAIRED
If the Calibrator appears damaged or operates abnormally, protection may be impaired.
Do not attempt to operate the Calibrator under these conditions. Refer all questions of
proper Calibrator operation to qualified service personnel.

Features of the 5520A Calibrator include the following:
•Automatic meter error calculation.
•Xand Dkeys that change the output value to pre-determined cardinal values
for various functions.
•Programmable entry limits that prevent invalid amounts from being entered.
•Simultaneous output of voltage and current, up to an equivalent of 20.9 kW.
•Pressure measurement when used with Fluke 700 Series pressure modules.
•10 MHz reference input and output. Use this to input a high-accuracy 10 MHz
reference to transfer the frequency accuracy to the 5520A, or to synchronize one or
more additional 5520As to a master 5520A.
•Simultaneous output of two voltages.
•Extended bandwidth mode outputs multiple waveforms down to 0.01 Hz, and sine
waves to 2 MHz.
•Variable phase signal output.
•Standard IEEE-488 (GPIB) interface, complying with ANSI/IEEE Standards
488.1-1987 and 488.2-1987.
•EIA Standard RS-232-C serial data interface for printing, displaying, or transferring
internally stored calibration constants, and for remote control of the 5520A.
•Pass-through RS-232-C serial data interface for communicating with the Unit Under
Test (UUT).
1-2. Operation Overview
The 5520A Calibrator may be operated at the front panel in the local mode, or remotely
using RS-232 or IEEE-488 ports. For remote operations, several software options are
available to integrate 5520A operation into a wide variety of calibration requirements.
1-3. Local Operation
Typical local operations include front panel connections to the Unit Under Test (UUT),
and then manual keystroke entries at the front panel to place the calibrator in the desired
output mode. The front panel layout facilitates hand movements from left to right, and
multiply and divide keys make it easy to step up or down at the press of a single key.
You can also review 5520A Calibrator specifications at the push of two buttons. The
backlit liquid crystal display is easy to read from many different viewing angles and
lighting conditions, and the large, easy-to-read keys are color-coded and provide tactile
feedback.
1-4. Remote Operation (RS-232)
There are two rear-panel serial data RS-232 ports: SERIAL 1 FROM HOST, and
SERIAL 2 TO UUT (Figure 1-2). Each port is dedicated to serial data communications
for operating and controlling the 5520A during calibration procedures. For complete
information on remote operations, see Chapter 5.
The SERIAL 1 FROM HOST serial data port connects a host terminal or personal
computer to the 5520A. You have several choices for sending commands to the 5520A:
you can enter commands from a terminal (or a PC running a terminal program), you can
write your own programs using BASIC, or you can run optional Windows-based
