Introduction

The Fluke Model 5700A/5720A Series II Calibrators are precise instruments that
calibrate a wide variety of electrical measuring instruments. These calibrators maintain
high accuracy over a wide ambient temperature range, allowing them to test instruments
in any environment, eliminating the restrictions to calibrate only in a temperature­controlled standards laboratory . With a 5700A/5720A Ser ies II, you can calibra te
precision multimeters that measure ac or dc voltage, ac or dc current, and resistance. The
5720A Series II operates in a similar manner to the 5700A Series II, the difference is that
the 5720A Series II has a considerably higher specified accuracy. Option 5700A-03
Wideband AC Voltage, which is available for both the 5700A Series II and the 5720A
Series II, extends this workload to include rf voltmeters.

The calibrator is a fully-programmable precision source of the following:

• 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

Wideband AC Voltage Module (Option 5700A-03)

Wideband AC Voltage Module (Opt ion 5700A-03)

The Wideband AC Voltage Module (Option 5700A-03) can be installed in both the
5700A and 5720A Series II Calibrators. The module is a high-accuracy, low-noise,
extremely flat ac voltage source for calibrating rf voltmeters, with a frequency range of
10 Hz to 30 MHz. Output is in seven ranges from 300 µV (-57 dBm) to 3.5 V

(+24 dBm) through a Type-N coaxial connector into a 50 Ω load. The output level is
selected in volts or dBm through either the front panel controls or under remote control.

The wideband module also functions with the calibrator’s output adjust controls that let
display the error of a wideband meter in either percentage of output or in decibels.

Included with the wideband module is a Type-N output cable and a 50 Ω terminator.
The wideband module is calibrated to the end of its standard-equipment output cable.

Auxiliary Amplifier

The Fluke Model 5725A Amplifier is available to extend the high voltage performance
and current range of the calibrator:

Interface connectors on the calibrator’s rear panel accept cables to directly operate a
5725A. Three amplifiers can be connected to the calibrator at the same time, but only
one output can be active at a time. Once you have connected the amplifiers and
configured the calibrator in a setup menu, amplifier operation is controlled by the
calibrator.

Getting Started

Operating instructions for the 5725A are provided in Chapter 4 of the Operators
Manual. The General Specifications include specifications for operating the calibrator
with the 5725A. For other amplifier specifications, refer to their instruction manuals.
Table summarizes the extended capabilities offered by the 5725A. Brief descriptions
of the extended capabilities follow.

Table 1. Auxiliary Amplifier Data

Model Mode Range

5725A Amplifier AC V 20 to 1100 V rms up to 70 mA, 40 Hz to 30 kHz

DC Amps 0 to ±11 A

DC Amps 1 to 11 A rms, 40 Hz to 10 kHz

5725A Amplifier

The Fluke 5725A Amplifier is an external unit operating under calibrator control to
extend ac voltage drive capabilities and both ac and dc current output range. The

amplifier adds the following capabilities to the calibrator’s 1100 V AC range with no
compromise in accuracy:

• Frequency limits at higher voltage increase to 100 kHz at 750 V, 30 kHz at 1100 V.

• Load limit increases to 70 mA for frequencies above 5 kHz.

• Capacitive drive increases to 1000 pF, subject to the maximum output current.

Extended-performance voltage is available at the calibrator’s front or rear binding
posts, eliminating the need to change cables during a procedure.

3

5700A/5720A Series II

Getting Started

A separate set of binding posts on the front panel of the 5725A supplies extended-range
ac and dc current outputs. Since most meters have a separate input terminal for the high
current ranges, this eliminates the need to change cables during a procedure. The
5725A can also be configured to source all current (both standard calibrator-generated
current and its own current) through the 5725A binding posts.

Support Equipment and Ser vices

Fluke supports your calibration needs with precision, high-quality equipment and a
wide range of services. Depending on your needs, location, and capabilities, you may
decide to support your 5700A/5720A Series II Calibrator independently or use Fluke
services for part, or all, of your support needs. The following paragraphs describe the
support equipment and services offered by Fluke for the calibrator. For specifications
and ordering instructions for this support equi pm ent and othe r Fluke ins tru men ts, re fer
to the Fluke catalog, or contact a representative at a Fluke Sales and Service Center.

732B Direct Voltage Reference Standard

The Fluke 732B is a rugged, easily transported solid state direct voltage reference
standard with a highly predictable 10 V output. This predictability allows the Fluke
Standards Laboratory, as well as many Fluke customers, to completely eliminate
fragile, saturated standard cells. Laboratories still maintain standard cells using the
732A and 732B as a transportable voltage standard, eliminating the need to transport
their standard cells. The 732B can be short-circuited, even for extended periods of time,
without damage or loss of stability. It maintains full specified stability over a

temperature span of 18 to 28 °C.
The calibrator uses a 10 V reference standard such as the Fluke 732B in its semi-

automated calibration procedure to establish external voltage traceability. Chapter 7 of
the Operators Manual describes this procedure.

732B-200 Direct Volt Maintenance Program (U.S.A. Only)

The Fluke 732B-200 Direct Volt Maintenance Program provides your laboratory with
NIST-traceable 10 V calibration uncertainty as low as 0.6 parts per million.

The program maintains the 732B that you keep in your laboratory. To accomplish this,
the following occurs:

1. Fluke sends you a calibrated Fluke-owned 732B standard, together with all-

necessary connecting cables and instructions for comparison with your 10 V
reference standard.

2. You take a series of readings over a five-day period, and return the results to the

Fluke Standards Laboratory.

3. The Fluke Standards Laboratory assigns a value to your 10 V standard relative to

the NIST legal volt and sends you a report of calibration.

742A Series Resistance Standards

The calibrator uses 1 Ω and 10 kΩ resistor standards such as the 742A Series in its
semi-automated calibration procedure to establish external traceability of resistance and
current. Chapter 7 of the Operators Manual describes this procedure.

The 742A Resistance Standards, which are constructed of arrays of Fluke wirewound
precision resistors, are ideally sui ted as suppo rt sta ndard s for the cal ib rat or. Stab il ity of
the resistance transfer standards and their temperature coefficients make them ideal for
easy transport to and operation in the calibrator's working environment.

4

Wideband AC Module (Option 5700A-03) Calibration Support

The Wideband AC Module (Option 5700A-03) requires two kinds of calibration: gain
and flatness. Gain constants are checked and recalibrated as a part of the normal
calibrator semi-automated calibration process.

Since frequency flatness is determined by such stable parameters as circuit geometry
and dielectric constants, flatness of the Wideband AC module has excellent long-term
stability. This stability gives the Wideband AC Module a two-year calibration cycle for
flatness calibration. Flatness calibration is required only infrequently, and can be done
when the calibrator is returned to a standards laboratory for periodic verification. The
5700A/5720A Series II Service Manual contains the wideband flatness calibration
procedure. Chapter 7 of the Operators Manual contains the wideband gain calibration
procedure.

5700A/5720A Series II

Getting Started

The Components of the 570 0A/5720A Series II Calibr ator

The calibrator is configured internally as an automated calibration system, with process
controls and consistent procedures. Internal microprocessors control all functions and
monitor performance, using a switching matrix to route signals between modules.
Complete automatic internal diagnostics, both analog and digital, confirm operational
integrity.

Reference amplifiers maintain dc accuracy and stability. Of all technologies available,
reference amplifiers have the lowest noise and best stability. Reference amplifiers in
the calibrator go through special selection processes including long-term aging to
ensure high reliability and performance well within specifications.

The calibrator achieves its exceptional ac voltage accuracy by using a patented Fluke
rms sensor to make real-time AC/DC comparison measurements. The Fluke rms sensor
is similar in principle to the traditional thermal voltage converter, but has a shorter time
constant, virtually no reversal error, higher signal-to-noise ratio, and better frequency
response. In the calibrator, one Fluke rms sensor serves as an AC/DC transfer standard
to develop gain and flatness correction constants during calibration. The second Fluke
rms sensor continuously monitors and corrects output voltage during operation.

A patented 26-bit digital-to-analog converter (dac) provides the calibrator with the
ability to precisely vary its output. This is a pulse-width-modulated dac with linearity
typically better than 0.2 ppm of full scale. As with the other internal functions, the
linearity of the dac is automatically checked during calibration and analog diagnostics.

Calibrating the 5700A/5720A Series II Calibrator

The traditional practice of returning a calibrator to a standards laboratory at regular
intervals for a full calibration is time consuming, expensive, and disruptive to the task
to which the calibrator is being applied. Moreover, it leaves gaps in confidence. You
must rely on manufacturer’s specifications to determine if a calibrator will perform
acceptably in an operating environment outs ide the lab. A lso, you mus t assu me that
drift is predictable enough so that performance is within limits between recalls.

The 5700A/5720A Series II Calibrator makes use of Fluke design breakthroughs in the
use of internal check standards and measurement systems. As a result, it can be
completely calibrated in place to full specifications using a small number of
convenient, portable, environmentally tolerant standards available from Fluke. As you
will see below, this procedure is traceable to military standard requirements.

When manufactured, each calibrator is calibrated and thoroughly verified with process
metrology and calibration standards traceable to the U.S. National Bureau of Standards.
A certificate of calibration is included.

A calibration verification procedure described in the 5700A/5720A Series II Service
Manual is recommended every two years or as required by your established policies.
This procedure involves no adjustments. It simply ensures internal processes are in
control, and establishes parallel exte rna l tra ceab il it y paths for in ter nal fun ct ions such as
ac transfers that are never adjusted or corrected.

Figure illustrates the time and money that can be saved by using the 5700A/5720A
Series II calibration support plan recommended by Fluke. Depending on your policies,
you may initially decide to perform calibration verification more often. The calibrator
makes this unnecessary and offers you a practical way to collect data unavailable with a
traditional calibrator design about performance between calibrations.

The Calibration Process

Calibration requires only three external standards: 10 V, 1 Ω, and 10 kΩ.
Environmentally-controlled internal check standards provide the primary reference
points. A stored table of calibration constants defines additional reference points for
controlling the output. Traceable calibration and adjustment to the specified level of
performance is accomplished in a semi-automated process that revises this table.

When you finish calibration, but before you save the new constants, the calibrator
presents you with the proposed adjustments as +/- ppm of range and percentage change
in specification for each range and function. You can print a list of changes through the
serial (RS-232C) port, or send them to a computer through either the seria l port or the
IEEE-488 port. Also on completion of calibration, the calibrator displays the largest
proposed change.

Calibration can be completed as far as deriving and printing the proposed adjustments
without changing the setting of the rear panel CALIBRATION switch; however, the
switch must be set to ENABLE to store the changes in nonvolatile memory and make
them effective. The switch is recessed to allow the metrologist to cover it with a
calibration sticker to guarantee calibrator integrity.

Establishing Traceability

Traceability to national standards is established as follows:

• Except for the internal AC/DC transfer standard, the internal check standards are

• The internal AC/DC transfer standard is never adjusted, so its traceability is not

• Infrequent independent verification is also performed on stable parameters, such as

Calibration Reports

The calibrator stores two sets of calibration constants: the set currently in use and the
old set from the previous calibration. This gives the calibrator the ability at any time to
produce a calibration report of the differences between the present settings and the
settings that were in effect before the last calibration. The report shows changes for
each range and function in +/- ppm of range and in percentage of specification limit.
You can print the report or send it to a host computer through either the RS-232-C or
IEEE-488 interface.

Series II is calibrated.

disturbed by calibration. Infrequent verification is done in the traditional way, by
comparing selected ac voltage outputs with an external dc voltage standard through
an external ac/dc transfer standard. Fluke recommends this is done every two years
or as determined by the policy of your organization.

frequency flatness, determined more by circuit geometry and dielectric constants
than time.

If you request a calibration report after doing calibration but before saving the new
constants, the report shows proposed changes to the calibration constants relative to the
previously stored settings.

Calibration Check

Checking the calibration takes about an hour, and provides you with a means of

documenting the calibrator’s performance of a between calibrations. Calibration
checking is similar to calibration, exce pt int ern al check st anda rds are used as primar y
references (no external standards are needed), and changes cannot be stored. The
process produces a report similar to normal ca lib rat ion, showi ng drift rel at ive to
internal check standards. Because cal check does not change stored calibration
constants, there is no need to enable the rear panel CALIBRATION switch. Therefore,
an external computer can do the procedure unattended.

Developing a Performance History

A Fluke specification is a set of performance limits that all products must meet. To
maintain consistent quality, Fluke calibrators are specified with enough margin to
include temperature, line, and load extremes, plus additional margin for production.
This means that a typical 5700A/5720A Series II calibrator in a typical environment
operates inside 50 % of specification limits. For some exacting applications, it can be
helpful to know just how accurately a particular calibrator operates. The proper way to
do this is to accumulate a performance history by calibrating regularly and recording
results on a control chart.

Getting Started

Calibration Check

Calibrating regularly and recording the results on a control chart is tedious and requires
a large array of equipment. The calibrator’s calibration check feature is an alternative
with some distinct advantages:

• Calibrated check standards are already programmed into the unit. You do not have

to use external standards.

• The process is consistent and automatic: it does not require an operator’s

assistance.

Each calibration check produces a new set of data points for accumulating a historical
record. When this process is externally automated, significant history can be
accumulated much faster than with a manual calibration.

Range Calibration

After calibration, you can make further fine adjustments to each range. Range
adjustments are optional; they are not necessary to meet total uncertainty specifications.
However, they do allow you to align your calibrator closer to your standards.

Before you do range calibration, you must first use the calibrator’s semi-automated
calibration procedure. This is to calibrate the ranges that will not be adjusted. It also
performs an initial adjustment for each range, and supplies flatness corrections for ac
functions.

DC Zeros Calibration

To ensure the validity of the specifications, a dc zeros calibration must be performed at
least every 30 days. If more than 30 days elapse without a dc zeros calibration a
warning message appears. This procedure does not require any external equipment or
connections and takes approximately 2.5 minutes to complete.

Specifications

The 5700A/5720A Series II Calibrators are verified and calibrated at the factory prior
to shipment to ensure they meet the accuracy stand ards required for all certified
calibration laboratories. By calibrating to the specifications in this manual, you can
maintain the high performance level throughout the life of your calibrator.

Specifications are valid after a warm-up period of twice the time the calibrator has been
turned off, up to a maximum of 30 minutes. For example, if the calibrator has been
turned off for five minutes, the warm-up period is ten minutes.

Specification Confidence Levels

You calibrator’s performance level is ensured by regular calibration to the primary
performance specifications, which are provided at both the 99 % and 95 % confidence
levels. The 95 % confidence level will provide an accuracy that will often surpass the
accuracy requirements for meeting Tag 4 standards, or a coverage factor of 2.
Calibration at the 99 % confidence level is also available for those applications that
require a confidence factor for the specifications that is higher than 95 %. For
information on selecting the confidence level, refer to Chapter 4 of the Operators
Manual.

The specification tables in this manual provide specifications at both the 95 % and 99
% confidence levels for the 5700A/5720A Series II Calibrators. Included with these
tables are operating specifications for using the calibrator with the Wideband AC
Module (Option 5700A-03) and the 5725A Amplifier.

Using Absolute and Relative Uncertainty Specifications

To evaluate the 5700A/5720A Series II coverage of your calibration workload, use the
Absolute Uncertainty specifications. Absolute uncertainty includes stability,
temperature coefficient, linearity, line and load regulation, and the traceability to
external standards. You do not need to add anything to absolute uncertainty to
determine the ratios between the calibrator’s uncertainties and the uncertainties of your
calibration workload.

Relative uncertainty specifications are provided for enhanced accuracy applications.
These specifications apply when range constants are adjusted (see “Range
Calibration”). To calculate absolute uncertainty, you must combine the uncertainties of
your external standards and techniques with relative uncertainty.

Using Secondary Performance Specifications

Secondary performance specifications and operating characteristics are included in
uncertainty specifications. They are provided for special calibration requirements such
as stability or linearity testing.

Notes:

1. Stability specifications are included in the Absolute Uncertainty values in the primary specification tables.

2. Temperature coefficient is an adder to uncertainty specifications that does not apply unless operated more

than 5 °C from calibration temperature, or calibrated outside the range 19 °C to 24 °C. Two examples:

• Calibrate at 20 °C: Temperature coefficient adder is not required unless operated below 15 °C or above
25 °C.

• Calibrate at 26 °C: Add 2 °C temperature coefficient adder. Additional temperature coefficient adder is
not required unless operated below 21 °C or above 31 °C.

3. Refer to current derating factors table for loads outside of this range.

4. Active two-wire compensation may be selected for values less than 100 kΩ, with either the front panel or the
meter input terminals as reference plane. Active compensation is limited to 11 mA load, and to 2 V burden.
Two-wire compensation can be used only with Ω-meters that source continuous (not pulsed) dc current.

Placement and Rack Mounting

Place the calibrator on top of a bench or mounted in a standard-width, 24-inch (61-cm)
deep equipment rack. For bench-top use, the calibrator is equipped with non-slipping,
non-marring feet. To mount the calibrator in an equipment rack, use the Rack Mount
Kit, Model Y-5737, instructions are included with the kit. For convenience, the rack
mount instruction sheet can be stored in the binder of this manual.

Cooling Considerations

Damage caused by overheating may occur if the area around
the air intake is restricted, the intake air is too warm, or the air
filter becomes clogged.

A hidden but important feature of the calibrator is its internal cooling system. Baffles
direct cooling air from the fans throughout the chassis to internally dissipate heat
during operation. The accuracy and dependability of all internal parts of the calibrator
are enhanced by maintaining the coolest possible internal temperature. By observing
the following rules, you can lengthen the life of the calibrator and enhance its
performance:

• The area around the air filter must be at least 3 inches from nearby walls or rack

enclosures.

• The exhaust perforations on the sides of the calibrator must be clear of

obstructions.

• The air entering the instrument must be room temperature. Make sure that exhaust

from another instrument is not directed into the fan inlet.

• Clean the air filter every 30 days or more frequently if the calibrator is operated in

a dusty environment. (Instructions for cleaning the air filter are in Chapter 7 of the
Operators Manual.)

Caution

36

Accessing the Fuse

To prevent instrument damage, verify that the correct fuse is
installed for the line voltage setting.

The line power fuse is accessible on the rear panel. The fuse rating label to the right of
the fuse holder (labeled F1) shows the correct rep laceme n t fus e rating for each li ne
voltage setting. To check or replace the fuse, refer to Figure 3 and proceed as follows:

1. Disconnect line power.

2. Using a standard screwdriver, loosen the fuse holder by turning the slot labeled F1

until the cap and fuse pop free.

3. Replace the fuse and holder.

Selecting Line Voltage

The calibrator arrives from the factory configured for the line voltage normally
appropriate for the country of purchase, or as specified at the time of your purchase
order. The calibrator also comes with the appropriate line power plug for the country of
purchase. If you need a different type, refer to Table 24 and Figure 4. They list and
illustrate the line power plug types available from Fluke.

Check the line power label on the rear panel of the calibrator to verify that the line
voltage matches local line power. Figure 5 shows the location of the line power label.

You can set the calibrator to operate from eight different nominal line voltages; each

voltage setting has a voltage tolerance of ± 10%, and frequency range of 47 to 63 Hz.
The line voltage switches are located on the bottom left side of the rear panel.

To change the line voltage setting, set the line voltage selection switches to the correct
setting shown in Figure 5.

Getting Started

Connecting to Line Power

After you verify that the line voltage selection switches are set to the correct positions,
verify that the correct fuse for that line voltage is installed. Connect the calibrator to a
properly grounded three-prong outlet.

Connecting a 5725A Amplifier

The calibrator provides an interface connector for the Fluke 5725A amplifier. You
designate the active amplifier for voltage and current boost in a setup menu. That
procedure is located in the beginning of Chapter 4 of the Operators Manual. Refer to
the 5725A Instruction Manual for the installation procedure.

Warning

To avoid shock hazard, connect the factory supplied three­conductor line power cord to a properly grounded power
outlet. Do not use a two-conductor adapter or extension cord;
this will break the protective ground connection. If a two­conductor power cord must be used, a protective grounding
wire must be connected between the ground terminal and
earth ground before connecting the power cord or operating
the instrument.

Selecting Output Binding Post s

The calibrator is equipped with binding posts for OUTPUT, SENSE, and V GUARD
(Voltage Guard) on the front and rear panels. Only one set of binding posts can be
enabled at the same time. (GND binding posts on both front and rear are always
connected to chassis ground.) The calibrator is shipped with the front panel binding
posts enabled. The procedure to enable the rear panel binding posts involves opening
the case of the calibrator, and repositioning a cable. This procedure is described in
Chapter 4 of the 5700A/5720A Series II Service Manual.

Note

A Type "N" connector for output from the Option 5700-03 Wideband AC

Voltage Module is available only on the calibrator’s front panel. A
terminal for I GUARD is available only on the rear panel. (Connection to
the I GUARD terminal is normally required only at low current levels in
calibration systems with long cable runs.) Chapters 3 and 4 of the
Operators Manual contain detailed information about the function and
use of all binding posts.

Front Panel Features

Front panel features (including all controls, displays, indicators, and terminals) are
shown in Figure 6. Each front panel feature is briefly described in Table 25.

Display Screen Saver

The Control Display (described in Table 25) is equipped with a screen saver that

lengthens the display’s life when the front panel is not being used. The display
becomes blank after 30 minutes of inactivity, unless it is one of the operating states that
override the screen saver.
