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 manual. The Product is a fully­programmable 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 Ω to 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 (5730A/03) or 50 MHz (5730A/05)

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.

Auxiliary Amplifiers

The Fluke Calibration Model 5725A and 52120A amplifiers are available to extend the
high voltage performance and current range of the 5730A Calibrator.

Interface connectors on the Calibrator rear panel accept cables to directly operate a
5725A and/or 52120A. Multiple amplifiers can be connected to the Calibrator at the same
time, but only one output can be active at a time. Once the amplifiers are connected and
configured in the Product Setup Menu, amplifier operation is controlled by the Calibrator.

A maximum of three 52120As can be connected to provide a maximum of 360 A rms ac
or 300 A dc current when their outputs are connected in parallel.

See Chapter 4 of the Operators Manual for instructions to operate both amplifiers. The
general specifications at the end of this manual include specifications to operate the
5730A Calibrator with both amplifiers. For other amplifier specifications, refer to their
instruction manuals. Table 2 summarizes the extended capabilities offered by the 5725A
and 52120A. Brief descriptions of the extended capabilities follow.

5725A Amplifier

The Fluke Calibration 5725A Amplifier is an external unit that operates under calibrator
control. It extends ac voltage drive capabilities and both ac and dc current output range.
The amplifier adds these capabilities to the 1100 V ac range of the 5730A Calibrator 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.

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 high­current 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.

732B Direct Voltage Reference Standard

The Fluke Calibration 732B is a rugged, easily transported solid state direct voltage
reference standard with a highly predictable 10 V output. The 732B can be short­circuited, even for extended periods of time, without damage or loss of stability. It
maintains full specified stability over a temperature span of 18 °C to 28 °C.

The 5730A Calibrator uses a 10 V reference standard such as the Fluke Calibration 732B
in its semi-automated calibration procedure to establish external voltage traceability.
Chapter 7 of the Operators Manual describes this procedure.

5730A

Getting Started Manual

732B-200 Direct Volt Maintenance Program (USA Only)

742A Series Resistance Standards

The Fluke Calibration 732B-200 Direct Volt Maintenance Program provides laboratories
with NIST-traceable 10 V calibration uncertainty as low as 0.6 parts per million (ppm).

The program maintains the 732B that is kept in the laboratory. To do this:

1. Fluke Calibration sends a calibrated Fluke Calibration-owned 732B standard,
together with all-necessary connection cables and instructions for comparison with a
customer 10 V reference standard.

2. The customer takes a series of readings over five days, and returns the results to the
Fluke Calibration Standards Laboratory.

3. The Fluke Calibration Standards Laboratory assigns a value to the customer 10 V
standard relative to the NIST legal volt and sends a report of calibration.

The 5730A 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 are constructed of arrays of Fluke Calibration wirewound
precision resistors and 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 the Calibrator work environment.

Wideband AC Module (Option 5730A/03 or 5730A/05) Calibration Support

The Wideband AC Module (Option 5730A/03 or 5730/05) requires two kinds of
calibration: gain and flatness. Gain constants are checked and recalibrated as part of the
normal 5730A 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.
Chapter 7 of the Operators Manual contains the wideband gain and flatness calibration
procedures.

The Components of the Calibrator

The 5730A Calibrator is configured internally as an automated calibration system, with
process controls and consistent procedures. Internal microprocessors control all functions
and monitor performance with the use of 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. Reference amplifiers have the
lowest noise and best stability. Reference amplifiers in the Calibrator go through special
selection processes that include long-term aging to ensure high reliability and
performance well within specifications.

8

Multifunction Calibrator

5730A Calibration

The Calibrator achieves its exceptional ac voltage accuracy by the use of a patented Fluke
Calibration rms sensor to make real-time ac/dc comparison measurements. The Fluke
Calibration 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 Calibration rms sensor serves
as an ac/dc or ac/ac transfer standard to develop gain and flatness correction constants
during calibration. The second Fluke Calibration rms sensor continuously monitors and
corrects output voltage during operation.

A patented 26-bit digital-to-analog converter (DAC) lets the Calibrator 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.

5730A Calibration

The 5730A Calibrator makes use of internal check standards and measurement systems.
As a result, it can be completely calibrated in place to full specifications with a small
number of convenient, portable, environmentally-tolerant standards available from Fluke
Calibration. This procedure is traceable to military standard requirements.

When manufactured, each Product is calibrated and thoroughly verified with process
metrology and calibration standards traceable to the International System of units (SI)
through well-recognized national metrology institutes. A certificate of calibration that is
accredited to ISO 17025 is included.

The calibration verification procedure is recommended every 2 years or as required by
established policies. This procedure involves no adjustments. It 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.

The Artifact Calibration Process

Calibration requires only three external standards or artifacts: 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 finished with artifact calibration, but before the new constants are saved, the
5730A Calibrator presents the proposed adjustments as +/- ppm of range and percentage
change in specification for each range and function. A list of changes can be sent to the
computer through the serial port, USB device port, Ethernet port, or the IEEE-488 port
using the remote command: CAL_RPT? CHECK. Also on completion of calibration, the
Calibrator shows the largest proposed change.

Calibration can be completed as far as deriving and printing the proposed adjustments
without entering the calibration protection passcode. To save the changes in non-volatile
memory to adjust future outputs from the Calibrator, the passcode must be entered from
the front panel or with a remote command. The passcode entry menu is shown on the
display when necessary.

Establish Traceability

Calibration Reports

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 Calibrator 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 Calibration recommends this to be done
every two years or as determined by the policy of your organization.

• Infrequent independent verification is also done on stable parameters, such as
frequency flatness, determined more by circuit geometry and dielectric constants than
time.

The 5730A 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 shifts in various
output values from before to after the most recent calibration for each range and function
in +/- ppm of range and in percentage of specification limit. The report can be saved to a
USB drive or retrieve it from a host computer through either the RS-232, USB device
port, Ethernet port, or IEEE-488 interface.

Range Adjustment

After calibration, further fine adjustments can be made to each range. Range adjustments
are optional and they are not necessary to meet total uncertainty specifications. However,
they can help to align the Calibrator closer to in-house standards.

Before range calibration is done, first do the Artifact Calibration as described later in this
manual. 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

DC Zeros is a quick, automatic process that corrects offset errors that increase with time
on several output ranges. If a 5725A Amplifier is attached, it also zeros the 11 A dc
range. This process takes approximately 2 ½ minutes (plus an additional 30 seconds for
the 5725A).

To execute dc zeros, from the normal operation screen:

1. Touch Setup Menu to show the Setup Menu. See the “Setup Menu” section of
Chapter 4 in the Operators Manual.

2. Touch the Calibration menu.

3. Touch Run DC Zero to start the dc zeros routine. The status of the dc zero
calibration is shown as the Calibrator progresses through a series of steps. When
completed, the Calibrator shows “Calibration complete”.

If the Calibrator is not warmed up, the display prompts to continue or
cancel the DC Zeros function.

Note

4. Touch Close to proceed with Calibrator use.

cord instead of through the earth ground binding post. Refer to "Cable Connection
Instructions" in Chapter 4 of the Operators Manual for details. Included with the
Calibrator is a brass strap that connects GROUND to V GUARD.

The V GUARD binding post provides an external connection point for the internal
voltage guard. For a UUT with floating (ungrounded) inputs, the V GUARD should
be connected to LO internally (External Guard OFF). For a UUT with a grounded
input, the V GUARD must be externally connected to the grounded UUT input
(External Guard on). The maximum allowable potential between the V GUARD
connector and chassis ground is 20 V peak. Refer to "When to use the External
Voltage Guard" and "Cable Connection Instructions" in Chapter 4 of the Operators

CURRENT OUTPUT binding post when calibrating a UUT with a separate current
input terminal. Refer to "Connect the Calibrator to the UUT" in Chapter 4 of the
Operators Manual for instructions for use of this binding post.

The SENSE binding post is used with resistance and voltage functions for sensing

at the UUT after the external sense has been selected by the touch of External
Sense or by remote command.

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 the two-wire ohms
function to allow the two-wire compensation circuitry to the UUT terminals. Refer to
"When to use External Sensing," "Four-Wire Vs. Two-Wire Resistance
Connections," and "Cable Connection Instructions" in Chapter 4 of the Operators
Manual for external sensing instructions and illustrations of SENSE connections.

Notes:

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

2. Temperature coefficient is an adder to Absolute 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.

1. For I < I L, errors occur due to thermally generated voltages within the 5730A. Use the following equation to determine the error,
and add this error to the corresponding specifications.

Error = K(I
Where: Error is in mΩ for all two-wire comp values and four-wire short, and in ppm for the remaining four-wire values.
K is the constant from the above table;

I and IL are expressed in mA for short to 1.9 kΩ;

Voltage compliance developed across inductive loads may prevent range maximum current output being achieved at

higher frequencies. The appropriate maximum frequency (Fmax) for a given load inductance and current is given by:

The maximum frequency calculated with this equation is only approximate. Series resistance and parallel capacitance
also affect the maximum achievable frequency.
