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.

OPERATOR SAFETY
SUMMARY
WARNING
HIGH VOLTAGE
is used in the operation of this equipment
LETHAL VOLTAGE
may be present on the terminals, observe all safety precautions!
To prevent electrical shock hazard, the operator should not electrically contact the
output HI or sense HI terminals or circuits connected to these terminals. During
operation, lethal voltages of up to 1100 V ac or dc may be present on these
terminals.
When the nature of the operation permits, keep one hand away from equipment to
reduce the hazard of current flowing through vital organs of the body.

Introduction
The Fluke Calibration 5730A Calibrator (the “Calibrator” or the “Product”) can calibrate
a wide variety of electrical measurement instruments. The 5730A Calibrator maintains a
high accuracy over a wide ambient temperature range. This accuracy lets the Calibrator
test instruments in any environment, and eliminates the restrictions to calibrate only in a
temperature-controlled standards laboratory. The Calibrator can calibrate precision
multimeters that measure ac or dc voltage, ac or dc current, and resistance. The Calibrator
also is available with a Wideband AC Voltage option which extends this workload to
include RF voltmeters.
Specifications are provided at the end of this chapter. The 5730A Calibrator is a fully-
programmable precision source of:
•DC voltage to 1100 V
•AC voltage to 1100 V, with output available from 10 Hz to 1.2 MHz
•AC and DC current to 2.2 A, with output available from 10 Hz to 10 kHz
•Resistance in values from 1 Ωto 100 MΩ, plus a short
•Optional wideband ac voltage from 300 μV to 3.5 V into 50 Ω(-57 dBm to
+24 dBm), 10 Hz to 30 MHz
Features of the 5730A Calibrator include:
•Internal environmentally-controlled references that let the Calibrator maintain full
performance over a wide ambient temperature range.
•Automatic meter error calculation obtained through the use of a simple output adjust
knob.
•Keys that multiply and divide the output value by 10. This simplifies work on meters
with calibration points at decade multiples of a fraction of full-scale.
•Programmable entry limits used to restrict the levels that can be entered into the
Calibrator. This prevents access to levels that may be harmful to equipment or
personnel.
•Continuous display of Calibrator specifications at the selected operation point,
calibration interval, and specification confidence level.
•An auxiliary current binding post to calibrate meters with separate current inputs
without the need to move cables.
•Real-time clock and calendar for date stamping reports and reminders issued to
perform the dc zeros calibration procedure within the required interval.
•Offset and scaling modes that simplify linearity tests of multimeters.
•Variable phase reference signal output and phase-lock input.

•Interface for the Fluke Calibration 5725A Amplifier.
•Interface for the Fluke Calibration 52120A Amplifier.
•Standard IEEE-488 (GPIB) interface, that complies with ANSI/IEEE Standards
488.1-1987 and 488.2-1987.
•EIA/TIA-574 Standard RS-232 serial data interface for remote control of the
Calibrator.
•Extensive internal self-testing and diagnostics of analog and digital functions
•Universal Serial Bus (USB) 2.0 high-speed interface device port for remote control of
the Calibrator.
•Integrated 10/100/1000BASE-T Ethernet port for network connection remote control
of the Calibrator.
•USB Host port to save calibration reports to a flash drive.
•Visual Connection Management output terminals illuminate to help show correct
cable connection configurations.
•Soft Power - automatic selection of line voltage/frequency.
•LCD Color VGA display with touch panel overlay.
•A traceable calibration procedure for all modes and ranges that requires only 10 V,
1 Ω, and 10 kΩexternal standards, with only occasional independent verification.
•Automated calibration check that provides added confidence between calibration
recalls, and data that can be used to document and characterize Calibrator
performance between calibration recalls.
