Introduction and Specifications
Introduction 1
1-1. 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 Series II, you can calibrate
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.

full performance over a wide ambient temperature range
• Automatic meter error calculation obtained through using a simple output adjust
knob; the display shows linearity, offset, and scale errors
• Keys that multiply and divide the output value by 10 to simplify work on meters with
calibration points at decade multiples of a fraction of full-scale
• Programmable entry limits used for restricting the levels that can be keyed into the
calibrator, preventing access to levels that may be harmful to equipment or personnel
• A s key that provides the capability of displaying the instrument’s specification at
the selected operating point, calibration interval, and specification confidence level
• An auxiliary current binding post that allows you to calibrate meters with separate
current inputs without moving cables
• Real-time clock and calendar for date stamping reports
• Offset and scaling modes that simplify linearity testing of multimeters
• Variable phase reference signal output and phase-lock input
• Interface for the Fluke 5725A Amplifier
• Standard IEEE-488 (GPIB) interface, complying with ANSI/IEEE Standards 488.1-
1987 and 488.2-1987
• Selectable normal remote mode or emulation of the Fluke 5100B and 5200A Series
calibrators in functions and response to system controller software

1-5. Wideband AC Voltage Module (Option 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.
1-6. 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.
Chapter 4 provides instructions for operating the 5725A. The general specifications at the
end of this chapter include specifications for operating the calibrator with the 5725A. For
other amplifier specifications, refer to their instruction manuals. Table 1-1 summarizes
the extended capabilities offered by the 5725A. Brief descriptions of the extended
capabilities follow.

1-7. 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.
Table 1-1. Auxiliary Amplifier Data
(50 mA < 5 kHz)
220 to 750 V rms up to 70 mA, 30 kHz to 100 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.
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.
1-8. Support Equipment and Services
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 equipment and other Fluke instruments, refer to the
Fluke catalog, or contact a representative at a Fluke Sales and Service Center.
1-9. 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.
1-6
The calibrator uses a 10 V reference standard such as the Fluke 732B in its semiautomated calibration procedure to establish external voltage traceability. Chapter 7
describes this procedure.
Introduction and Specifications
Support Equipment and Services 1
1-10. 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.
1-11. 742A Series Resistance Standards
The calibrator uses 1 Ω and 10 kΩ resistor standards such as the 742A Series in its semiautomated calibration procedure to establish external traceability of resistance and
current. Chapter 7 describes this procedure.
The 742A Resistance Standards, which are constructed of arrays of Fluke wirewound
precision resistors, are ideally suited as support standards for the calibrator. Stability of
the resistance transfer standards and their temperature coefficients make them ideal for
easy transport to and operation in the calibrator's working environment.
1-12. 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 this manual contains the wideband gain calibration procedure.
1-13. Service Centers
A worldwide network of Fluke service centers supports Fluke instruments and assists
customers in many ways. Most service centers have standards and calibration laboratories
certified by local national standards organizations. The following is a partial list of the
services provided by most service centers:
• Repair and certified traceable calibration of all Fluke products.
• Certified traceable calibration of many non-Fluke standards and calibrators.
• Worldwide exchange of calibrator internal modules. Delivery inside the U.S.A. is
typically within 48 hours.

1-14. The Components of the 5700A/5720A Series II Calibrator
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.
applications, and product maintenance.
custom software, site evaluation and installation.
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.
1-15. 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 outside the lab. Also, you must assume 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.
1-8
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

Calibrating the 5700A/5720A Series II Calibrator 1
procedure involves no adjustments. It simply ensures internal processes are in control,
and establishes parallel external traceability paths for internal functions such as ac
transfers that are never adjusted or corrected.
Figure 1-1 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.

1-16. 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 serial 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.
1-17. Establishing Traceability
Traceability to national standards is established as follows:
• Except for the internal AC/DC transfer standard, the internal check standards are
directly calibrated by traceable external standards every time the 5700A/5720A
Series II is calibrated.
• The internal AC/DC transfer standard is never adjusted, so its traceability is not
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.
• Infrequent independent verification is also performed on stable parameters, such as
frequency flatness, determined more by circuit geometry and dielectric constants than
time.
1-18. 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.
1-10
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.
Introduction and Specifications
Calibration Check 1
1-19. 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, except internal check standards are used as primary references
(no external standards are needed), and changes cannot be stored. The process produces a
report similar to normal calibration, showing drift relative 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.
1-20. 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.
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.
1-21. 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.
1-22. 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.

Operators Manual
1-23. Specifications
The 5700A/5720A Series II Calibrators are verified and calibrated at the factory prior to
shipment to ensure they meet the accuracy standards required for all certified calibration
laboratories. By calibrating to the specifications in this chapter, 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.

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.
The tables in this chapter 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.
1-25. 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.
1-26. 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.

Or, visit Fluke's Web site at www.fluke.com
.
2-5. 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.
2-6. Cooling Considerations
Caution
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.)

2-7. Accessing the Fuse
Caution
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 replacement fuse rating for each line
voltage setting. To check or replace the fuse, refer to Figure 2-1 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.

2-8. 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 2-2 and Figure 2-2. 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 2-3 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

2-9. 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.
2-10. 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. 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 two-conductor
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.
2-11. Selecting Output Binding Posts
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 contain
detailed information about the function and use of all binding posts.

3-1. Introduction
This chapter is a reference for the functions and locations of the calibrator's front and rear
panel features, and provides brief but thorough descriptions of each features, for quick
access. Please read this information before operating the calibrator. Front panel operating
instructions for the calibrator are provided in Chapter 4, and remote operating
instructions are provided in Chapter 5.
3-2. Front Panel Features
Front panel features (including all controls, displays, indicators, and terminals) are shown
in Figure 3-1. Each front panel feature is briefly described in Table 3-1.
3-3. Display Screen Saver
The Control Display (described in Table 3-1) 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.
If the screen saver is in effect, you can restore the display by pressing C. Pressing
another key, or turning the knob, will also restore the display in addition to performing
the command selected by the key or knob.
The screen saver will not go into effect after 30 minutes of inactivity if:
• the Setup Menu or any of its submenus are displayed
• the calibrator is being operated under remote control
• the calibrator is undergoing calibration or diagnostics
• an error message is displayed

External Sensing should be used in the dc voltage function when the UUT
draws enough current to produce a significant voltage drop in the cables,
and in the resistance function when the UUT has a four-wire ohms input and
the calibrator is set to 100 kΩ or less. External sensing can also be used in
conjunction with the two-wire compensation circuit to compensate for lead
resistance at the UUT terminals. Refer to "When to use External Sensing,"
"Four-Wire vs. Two-Wire Resistance Connections," and "Cable
Connections" in Chapter 4 for external sensing instructions.
Opens and closes an internal connection between V GUARD (voltage guard)

When available, an amplifier is automatically selected for output settings that
exceed the calibrator’s capabilities but fall within the limits of the selected
amplifier. The B key is only needed to activate an amplifier for an output
setting that is available from either the calibrator or the amplifier. This allows
you to take advantage of amplifier capabilities besides extended range, such
as higher compliance voltage.
For both voltage and current, the amplifier is assumed to be a 5725A unless
another model is designated in the setup menus.

Introduction 4
4-1. Introduction
This chapter provides instructions for operating the calibrator from the front panel, which
includes all aspects of setting up and configuring the calibrator. Sample applications are
included that describe how to calibrate a Fluke 70 Series Multimeter and an 8840A Series
Digital Multimeter. Descriptions and instructions for programming offsets, scale factors,
and linearity checks are also provided.
Before you begin following the procedures in this chapter, you should be familiar with
the front panel controls, displays, and terminals, which are identified and described in
detail in Chapter 3. Once you are familiar with the front panel, be sure to warm up the
calibrator and ensure its dc zeros calibration, in accordance with the instructions at the
beginning of this chapter. For information on using remote commands to operate the
calibrator, refer to Chapter 5.
WWarning
The calibrator is capable of supplying lethal voltages. Do not
make connections to the output terminals when any voltage is
present. Placing the instrument in standby may not be enough
to avoid shock hazard, since the O key could be pressed
accidentally. Press r and verify that standby is lit before
making connections to the output terminals.

Operators Manual
4-2. Powering on the Calibrator
When you power on the calibrator, the Control Display appears as shown below and then
displays a series of tests, as the calibrator performs self-tests. If a self test fails, a prompt
on the Control Display identifies the failed test and lets you choose whether to continue
self testing or stop and run self diagnostics. For information about self-diagnostics, refer
to Chapter 3 of the 5700A/5720A Series II Service Manual.
WWarning
To avoid electric shock, make sure the calibrator is safely
grounded as described in Chapter 2.
Caution
Before turning the calibrator on, make sure that the line voltage
selection switches are set properly for your line voltage. Refer
to Figure 2-3 or to the line voltage switch label and check the
line voltage now if you have not already done so.
After the calibrator passes its self-tests, it powers up to 0V dc in standby, configured for
internal sensing and internal guard, ready to accept an entry from the keypad. The
Control Display now appears as shown below:
PREV
MENU
4-3. Warm Up
The calibrator must always be warmed up, to allow the environmentally controlled
components inside to stabilize, and to ensure that it meets or exceeds the specifications
listed in Chapter 1. Sufficient warmup times are as follows:
• If the calibrator has been powered off for one hour or more, allow at least 30 minutes
of warmup time.
• If the calibrator has been powered off for a length of time less than one hour, allow it
to warm up for at least twice the length of time it was turned off. For example, if it
has been turned off for 10 minutes, allow at least 20 minutes of warmup time.

DC Zeros 4
4-4. DC Zeros
DC zeros is a quick, automatic process that removes any offset error on the 11V and 2.2V
ranges, and removes offset and gain errors on the 220 mV range. If a 5725A Amplifier is
attached, it also zeros the 11A dc range. This process takes about 2.5 minutes (plus an
additional 30 seconds for the 5725A).
4-5. Executing DC Zeros
To execute dc zeros, proceed as follows from the power-up state:
1. Press the following sequence of softkeys:
“Setup Menus”→“Cal” →“Zero”
2. When the process is finished, a message appears that tells you to press any key to
continue. Press any key to exit the dc zeros display.
3. To return to normal operation, press P twice.
4-6. DC Zeros Reminder
Specifications require that dc zeros be executed at least every 30 days. If the 30-day time
period elapses and dc zeros is not performed, the following message appears on the
display when the calibrator is powered on, or reset.
PREV
MENU
To override the message and perform dc zeros at a more convenient time, press the
softkey under ZERO LATER (the softkey next to P). To perform dc zero at this time,
press one of the softkeys under ZERO NOW.
Note
If you receive this message after powering on the calibrator, allow the
calibrator to warm up before executing dc zeros. Otherwise an error
message appears indicating that the calibrator is not warmed up. To ensure
the best performance, the warmup period should be completed.

4-11. Setting the Internal Clock/Calendar
An internal clock/calendar provides the date (corrected for leap years) and time to the
calibrator’s CPU (Central Processing Unit). The clock setting should be checked and set
if necessary.
Note
A long-life lithium battery keeps the clock/calendar running during poweroff periods. If the battery in your calibrator should ever need replacement,
refer to the Service Manual. The battery is a button-type, soldered to the
CPU Assembly (A20). Any procedure that involves removing the cover is
for service personnel only.
To set or change the time and date of the internal clock/calendar, proceed as follows:
1. If you want to set the date or both date and time, set the rear panel CALIBRATION
switch to ENABLE (see Figure 3-2). The setting of the CALIBRATION switch does
not matter for setting time only.

The softkey labeled “Instmt Config” in the setup menu gives you access to the following
information:
• Installed internal operating software revision letters.
• Whether the Wideband AC Module (Option 5700A-03) is installed.
• Which auxiliary amplifiers are attached, if any.
• The contents of the user report string (a general-purpose data storage location that is
changeable only in remote control using the RPT_STR command). You can use this
register to store a property identification name or number, verification test record
number, or other message. The message appears on calibration report printouts as
described in Chapter 6. The rear panel CALIBRATION switch must be in the
ENABLE position to change the user report string. Refer to Chapter 5 for how to use
the RPT_STR remote command.
To view this information, proceed as follows:
1. Press the “Setup Menus” softkey, then press the “Instmt Config” softkey. The display

4-14. Special Functions Menu.
The softkey labeled “Special Functns” in the setup menu provides access to the AC Xfer
Choice and the Date Format feature, which lets you select one of three date formats
(m/d/y, d.m.y, and ymd). In remote, use DATEFMT to set the date format and
DATEFMT? to query the date format. The AC Xfer Choice feature activates another
softkey that lets you turn off the monitoring system that makes adjustments for load
changes. The AC Xfer OFF feature is available only in the ranges below 220V, at
frequencies below 120 kHz.
The AC Xfer OFF function remains active until the calibrator is reset or the power is
turned off. For remote control applications, the same feature is accessible through the
remote command XFER OFF. Send the command XFER ON to restore internal ac
transfers to normal operation.
Turn off internal ac transfers as follows:
1. Press the “Setup Menu” softkey.
2. Press the “Special Functns” softkey.
3. Press the “AC Xfer Choice” softkey so that ON appears. This turns on an “Intrnl
Xfers” softkey in the ac voltage function.
4. Press P twice.
5. After setting the output for an ac voltage, press the “Intrnl Xfers” softkey so that OFF
appears. This will inhibit internal transfers from being made after the output has
settled. It is particularly useful for making ppm level measurements at low
frequencies. Changing the calibrator's output will reinitiate transfers until the output
has settled.
4-15. Resetting the Calibrator.
At any time during front panel operation, you can return the calibrator to the power-up
state by pressing r. Pressing r does the following:
• Returns the calibrator to the power-up state: 0 mV dc, standby, internal guard, and
internal sense.
• Clears the stored values for limits, offset, scale, and error mode reference.
4-12
Front Panel Operation
Operate and Standby Modes 4
4-16. Operate and Standby Modes
When the OPERATE annunciator is lit, the output value and function shown on the
Output Display are active at the selected terminals. When the STANDBY annunciator on
the Output Display is lit, all calibrator binding posts except GROUND are open-circuited.
To toggle between operate and standby modes, press O.
If any of the following events occur during operation, the calibrator automatically
switches to standby mode:
• The r key is pressed.
• A voltage ≥22V is selected when the previous output voltage was less than 22V.
• The output location is changed, for example by selecting an amplifier. The exception
is when the 5725A is selected for ac voltage or current, provided the calibrator’s
current output location is set to “5725A.”
• The output function is changed from any of the following: a voltage much less than
22V, an ac voltage much greater than 22V, a dc voltage much greater than 22V, a dc
current, an ac current, or a resistance. The exception is when the calibrator is in
5100B mode when switching between dc and ac current. In this case the calibrator
will not switch to standby mode.
4-17. Connecting the Calibrator to a UUT
WWarning
The calibrator is capable of supplying lethal voltages. Do not
make connections to the output terminals when any voltage is
present. Placing the instrument in standby may not be enough
to avoid shock hazard, since the O key could be pressed
accidentally. Press reset and verify that standby is lit before
making connections to the output terminals.
The binding posts labeled OUTPUT (HI, LO, and AUX I) deliver voltage, fixed
resistance, and current to the UUT (Unit Under Test). The Type “N” connector on the
front panel labeled WIDEBAND delivers the output signal from the Option 5700A-03
Wideband AC Module.
Depending on the output function, output amplitude, and input configuration of the UUT
(Unit Under Test) or meter, connection to the SENSE binding posts, the GUARD binding
post, and the GROUND binding post may also be required or recommended. The text in
this chapter explains how and when to use these binding posts.
4-18. Recommended Cable and Connector Types
Cables can be connected to the binding posts using banana jacks, terminal lugs, or
stripped insulated wire. To avoid errors induced by thermal voltages (thermal emfs), use
connectors and conductors made of copper or materials that generate small thermal emfs
when joined to copper. Avoid using nickel-plated connectors. Optimum results can be
obtained by using Fluke Model 5440A-7002 or 5440A-7003 Low Thermal EMF Test
Leads.
Cable requirements depend on the output function, amplitude, and frequency. Table 4-1
gives specific cable recommendations for all applications.

1. Spade lugs provide a slightly better thermal EMF performance. However, some UUTs have repressed
banana connectors that cannot accommodate spade lugs.
4-19. When to Use External Sensing
External sensing is normally required only when you are calibrating a device that draws
enough current to produce a significant voltage drop in the cables. An example of such a
case is using the calibrator as an external dc voltage reference for an AC/DC transfer
standard. In this example, the calibrator is sourcing 1V dc into a Fluke 540B AC/DC
Transfer Standard. The 180Ω input impedance results in a current flow of approximately
5 mA. The calibrator’s 90-day uncertainty at 1V is specified to be ±(6 ppm + 1.2 uV) or ±
7.2 µV. Cumulative lead and contact resistances of as little as 2 mΩ would cause a
voltage drop greater than the total uncertainty of the calibrator. External sensing
eliminates this error.
The normal power-up state of the calibrator is external sensing off, with an internal
connection between the SENSE and OUTPUT automatically made. This is the state
achieved by pressing X so that the indicator is off.
