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.

Operators Manual
Overload Protection
Operation Overview
The Calibrator supplies reverse-power protection, fast output disconnection, and/or fuse
protection on the output terminals for all functions.
Reverse-power protection prevents damage to the calibrator from occasional, accidental,
normal-mode, and common-mode overloads to a maximum of ±300 V peak. It is not
intended as protection against frequent (systematic and repeated) abuse. Such abuse will
cause the Calibrator to fail.
For volts, ohms, capacitance, and thermocouple functions, there is fast output
disconnection protection. This protection senses applied voltages higher than 20 volts on
the output terminals. It quickly disconnects the internal circuits from the output terminals
and resets the calibrator when such overloads occur.
For current and aux voltage functions, user replaceable fuses supply protection from
overloads applied to the Current/Aux Voltage output terminals. The fuses are accessed by
an access door on the bottom of the calibrator. You must use replacement fuses of the
same rating and type specified in this manual, or the protection supplied by the Calibrator
will be compromised.
The Calibrator can be operated at the front panel or remotely with the RS-232 or IEEE488 ports. For remote operations, software is available to integrate 5502A operation into
a wide variety of calibration requirements.
Local Operation
Typical local operations include front-panel connections to the UUT, and then manual
keystroke entries at the front panel to put the Calibrator in the necessary output mode.
and make it easy to step up or down at the push of a key. You can also examine
Calibrator specifications at the push of two buttons. The backlit LCD is easy to read from
many different angles and can be read in dim or bright light. The large, easy-to-read keys
are color-coded and give tactile feedback.
Remote Operation (RS-232)
There are two rear-panel serial data RS-232 ports: SERIAL 1 FROM HOST, and
SERIAL 2 TO UUT (see Figure 1-2). Each port is dedicated to serial-data
communications to operate and control the Product during calibration procedures. For
complete information on remote operation, see Chapter 5.
The SERIAL 1 FROM HOST serial data port connects a host terminal or personal
computer (PC) to the Calibrator. To send commands to the Calibrator: enter commands
from a terminal (or a PC running a terminal program), write your own procedures with
BASIC, or use optional Windows-based software such as MET/CAL Plus.

Introduction and Specifications
Operation Overview 1
The SERIAL 2 TO UUT serial data port connects a UUT to a PC or terminal with the
5502A (see Figure 1-2). This “pass-through” configuration removes the requirement for
two COM ports at the PC or terminal. A set of four commands control the operation of
the SERIAL 2 TO UUT serial port. See Chapter 6 for a discussion of the UUT_
commands.

Remote Operation (IEEE-488)
The rear-panel IEEE-488 port is a fully programmable parallel interface bus that
complies with standard IEEE-488.1 and supplemental standard IEEE-488.2. When the
Calibrator is used by remote control of an instrument controller, the Calibrator operates
exclusively as a “talker/listener.” You can write your own programs with the IEEE-488
command set or run the optional Windows-based MET/CAL Plus software. See Chapter
6 for a discussion of the commands available for IEEE-488 operation.

Formula 60-T-I minutes any 60 minute period where T is the temperature in °C (room temperature is about 23 °C) and I is the
output current in amperes. For example, 17 A, at 23 °C could be provided for 60-23-17 = 20 minutes each hour. When the 5502A
is outputting currents between 5 and 11 amps for long periods, the internal self-heating reduces the duty cycle. Under those
conditions, the allowable "on" time indicated by the formula and Figure 1-3 is achieved only after the 5502A is outputting currents

[1] Duty Cycle: Currents <11 A may be provided continuously. For currents >11 A, see Figure 1-3. The current may be
provided 60-T-I minutes any 60 minute period where T is the temperature in °C (room temperature is about 23 °C) and I is
the output current in amps. For example, 17 A, at 23 °C could be provided for 60-17-23 = 20 minutes each hour. When the
5502A is outputting currents between 5 and 11 amps for long periods, the internal self-heating reduces the duty cycle.
Under those conditions, the allowable "on" time indicated by the formula and Figure 1-3 is achieved only after the 5502A is
outputting currents <5 A for the "off" period first.
[2] For compliance voltages greater than 1 V, add 1 mA/V to the floor specification from 1 to 5 kHz.
[3] For compliance voltages greater than 1 V, add 5 mA/V to the floor specification from 5 to 10 kHz.

[1] Duty Cycle: Currents <11 A may be provided continuously. For currents >11 A, see Figure 1-3. The current may be
provided 60-T-I minutes any 60 minute period where T is the temperature in °C (room temperature is about 23 °C) and I is
the output current in amps. For example, 17 A, at 23 °C could be provided for 60-17-23 = 20 minutes each hour. When the
5502A is outputting currents between 5 and 11 amps for long periods, the internal self-heating reduces the duty cycle.
Under those conditions, the allowable "on" time indicated by the formula and Figure 1-3 is achieved only after the 5502A is
outputting currents <5 A for the "off" period first.
[2] For currents >11 A, Floor specification is 4000 μA within 30 seconds of selecting operate. For operating times >30 seconds,
the floor specification is 2000 μA.
[3] For currents >11 A, Floor specification is 1000 μA within 30 seconds of selecting operate. For operating times >30 seconds,
the floor specification is 5000 μA.

AC and DC Power Specifications
Power is simulated through the controlled simultaneous outputs of voltage and current from the Calibrator. While the
amplitude and frequency ranges of the outputs are broad, there are certain combinations of voltage and current where the
specifications are valid. In general these are for all dc voltages and currents, and AC voltages of 30 mV to 1020 V, ac
currents from 33 mA to 20.5 A, for frequencies from 10 Hz to 30 kHz. Operation outside of these areas, within the overall
calibrator capabilities, is possible, but it is not specified. The table and figure below illustrate the specified areas where
power and dual output are possible.

Because there are an infinite number of combinations, you must calculate the actual ac power uncertainty for your
selected parameters. The method of calculation is best shown in the subsequent examples (with 1-year specifications):
Example 1 Output: 100 V, 1 A, 60 Hz, Power Factor = 1.0 (Φ=0).
Voltage Uncertainty Uncertainty for 100 V at 60 Hz is 0.050 % + 3 mV, totaling: 100 V x .0.0005 = 50 mV added to
3 mV = 53 mV. Expressed in percent: 53 mV/100 V x 100 = 0.053 % (see “AC Voltage (Sine Wave) Specifications”).
Current Uncertainty Uncertainty for 1 A at 60 Hz is 0.05 % +100 μA, totaling: 1 A x 0.0005 = 500 μA added to
100 μA = 0.6 mA. Expressed in percent: 0. 6 mA/1 A x 100 = 0.06 % (see “AC Current (Sine Waves) Specifications”).
Phase Uncertainty (Watts) Adder for PF = 1 (Φ=0) at 60 Hz is 0 % (see “Phase Specifications”).
Total Power Uncertainty =
power
2
Example 2 Output: 100 V, 1 A, 400 Hz, Power Factor = 0.5 (Φ=60)
Voltage Uncertainty Uncertainty for 100 V at 400 Hz is 0.050% + 3 mV, totaling: 100 V x .0.0005 = 50 mV added to
3 mV = 53 mV. Expressed in percent: 53 mV/100 V x 100 = 0.053 % (see “AC Voltage (Sine Wave) Specifications”).
Current Uncertainty Uncertainty for 1 A at 400 Hz is 0.05 % +100 μA, totaling: 1 A x 0.0005 = 500 μA added to
100 μA = 0.6 mA. Expressed in percent: 0. 6 mA/1 A x 100 = 0.06 % (see “AC Current (Sine Waves) Specifications”).
Phase Uncertainty (Watts) Adder for PF = 0.5 (Φ=60) at 400 Hz is 2.73 % (see “Phase Specifications”).
Total Power Uncertainty =
power
2
VARs When the Power Factor approaches 0.0, the Watts output uncertainty becomes unrealistic because the dominant
characteristic is the VARs (volts-amps-reactive) output. In these cases, calculate the Total VARs Output Uncertainty, as
shown in example 3:
Example 3 Output: 100 V, 1 A, 60 Hz, Power Factor = 0.174 (Φ=80)
Voltage Uncertainty Uncertainty for 100 V at 60 Hz is 0.050% + 3 mV, totaling: 100 V x .0.0005 = 50 mV added to
3 mV = 53 mV. Expressed in percent: 53 mV/100 V x 100 = 0.053 % (see “AC Voltage (Sine Wave) Specifications”).
Current Uncertainty Uncertainty for 1 A at 60 Hz is 0.05 % +100 μA, totaling: 1 A x 0.0005 = 500 μA added to
100 μA = 0.6 mA. Expressed in percent: 0. 6 mA/1 A x 100 = 0.06 % (see “AC Current (Sine Waves) Specifications”).

output specification for 100 V, 100 Hz, is 0.039 % + 3 mV. For the dual

Introduction
This chapter has instructions to unpack and install the Calibrator, select the line voltage,
replace the fuse, and connect to line power. Instructions for cable connections other than
line power are in these chapters:
• UUT (Unit Under Test) connections: Chapter 4, “Front Panel Operation”
• IEEE-488 parallel interface connection: Chapter 5, “Remote Operation”
• RS-232 serial interface connection: Chapter 5, “Remote Operation”
To prevent possible electrical shock, fire, or personal injury:
• Properly terminate the sense leads to prevent exposure to
hazardous voltages on the sense terminals. The voltage
sense terminals are at output voltage when the two-wire
function is set.
• Do not touch exposed metal on banana plugs, they can have
voltages that could cause death.
• Do not use a two-conductor mains power cord unless you
install a protective ground wire to the Product ground
terminal before you operate the Product.
• Make sure that the Product is grounded before use.
Warning
Unpack and Inspection
The calibrator is shipped in a container to prevent damage. Examine the calibrator

Select Line Voltage
The calibrator comes from the factory configured for the line voltage typically applicable
for the country of purchase, or as specified at the time of your purchase order. You can
operate the Calibrator from one of four line-voltage settings: 100 V, 120 V, 200 V, and
240 V (47 Hz to 63 Hz). To verify the line-voltage setting, note the voltage setting that
you can see through the window in the power-line fuse compartment cover (Figure 2-1).
The permitted line-voltage variation is 10 % above or below the line-voltage setting.
To change the line-voltage setting, complete the following procedure:
1. Disconnect line power.
2. To open the fuse compartment, put a screwdriver blade in the tab on the left side of
the compartment and pry until it can be removed.
3. To remove the line-voltage selector assembly, hold the line-voltage indicator tab with
pliers and pull it straight out of its connector.
4. Turn the line-voltage selector assembly to the necessary voltage and reinsert.
5. Make sure to use the correct fuse for the selected line voltage (100 V/120 V, use
5 A/250 V slow blow, 220 V/240 V, use 2.5 A/250 V slow blow). To install the fuse
compartment, push it into position until the tab locks.
Connect to Line Power
To prevent possible electrical shock, fire, or personal injury:
• Do not use a two-conductor mains power cord unless you
install a protective ground wire to the Product ground
terminal before you operate the Product.
• Do not use an extension cord or adapter plug.
Make sure that the Product is grounded before use. The calibrator is shipped with the
correct line-power plug for the country of purchase. If it is necessary to use a different
type, refer to Table 2-2 and Figure 2-2 for a list and illustration of the line-power plug
types available from Fluke Calibration.
After you make sure that the line voltage selection is set correctly and that the correct
fuse for that line voltage is installed, connect the calibrator to a correctly-grounded
three-prong outlet.

Airflow Considerations 2
Airflow Considerations
Warning
For safe operation and maintenance of the Product, make sure
that the space around the Product meets minimum
requirements.
Baffles put cool air from the fan into the chassis to internally dissipate heat when the
Calibrator is in operation. The accuracy and dependability of all internal parts of the
calibrator are enhanced by a cool internal temperature. You can increase the life of the
Calibrator and enhance its performance by these rules:
• The area around the air filter must be a minimum 3 inches from close walls or rack
enclosures.
• The exhaust perforations on the sides of the Calibrator must be clear of blockage.
• The air that gets to the Calibrator must be at room temperature. Make sure the
exhaust air from other instruments does not enter into the fan inlet.
• Clean the air filter after 30 days or more frequently if the calibrator is operated in a
dusty environment. (See the “Maintenance” chapter for instructions to clean the air
filter.)

Output Display
The Output Display is a two-line backlit LCD that shows output amplitudes, frequency, and
calibrator status. Output values (or potential output values if in standby) are shown with a
maximum of seven digits plus a polarity sign. Output frequencies (or potential output frequencies
if the Calibrator is in standby) are shown with four digits. Calibrator status is shown by these
abbreviations:
OPR Shown when an output is active at the front panel terminals.
STBY Shown when the Calibrator is in standby.
u When you change the output, “u” (unsettled) is shown until the output moves in to the
specified accuracy.
m Shown while the Calibrator measures. (Thermocouple and impedance measurement
only.)
? Shown when the amplitude is specified as typical only, and/or decreased resolution.
This occurs when you operate the Calibrator in extended-bandwidth mode.
C Shown when the amplitude is specified as typical only, and/or decreased resolution.
This occurs when you operate the Calibrator in extended-bandwidth mode.
Control Display
The Control Display is a multipurpose backlit LCD used to show data entries, UUT error
adjustments, softkey names, phase angles, watts, power factors, and other prompts and
messages. When there is not room on the Output Display, output frequency is shown on the
Control Display. Softkey names tell you the function of the softkey directly below them. Groups of
softkey names together make a menu. The menus give access to many different functions with the
five softkeys plus the PREV MENU key. (See Figure3-3, Softkey Menu Tree.)

The STBY (Standby) key puts the Calibrator in standby mode. Standby mode is shown by “STBY”
in the lower left corner of the Output Display. In standby mode, the NORMAL, AUX and 20A
output terminals are internally disconnected from the Calibrator. The Calibrator starts in standby
mode. The Calibrator automatically changes to standby if:
• is pushed.
• A voltage ≥33 V is selected when the previous output voltage was <33 V.
• The output function changes. When you change from ac or dc voltage <33 V, the Calibrator
does not change to STBY.
• A current output more than 3 A is selected. This is when the output location changes to the
20A terminal.
• An overload condition is sensed.
The OPR (Operate) key puts the Calibrator in operate mode. Operate mode is shown by “OPR” in
the lower left corner of the Output Display and the illuminated indicator on .
The EARTH (Earth Ground) key opens and closes an internal connection from the NORMAL
LO terminal to earth ground. An indicator on the key shows when this connection is made. The
power-up default condition is earth disabled (indicator off).
The SCOPE (Oscilloscope) key starts or stops an oscilloscope calibration option (if it is installed).
An indicator on the key shows when the option is active. If an oscilloscope calibration option is not
installed in the Calibrator and the SCOPE key is pushed, the calibrator shows an error message.
The TRIG OUT (Trigger Out) key sets the external trigger when in the scope mode. An indicator
on the key shows when external trigger output is active. If the Calibrator is not in scope mode
when is pushed, the beeper will sound.
The PREV MENU (Previous Menu) key recalls the previous set of menu selections. Each push of
this key retreats up one level of the menu tree until the display shows the top-level menu selection
of the function selected.
Softkeys
The functions of the five unlabeled blue softkeys are shown by names on the Control Display
above each key. The functions change when in operation so that many different functions can be
accessed with these keys. A group of softkey names is a menu. A group of connected menus is
called a menu tree.

The SETUP (Setup Menu) key puts the Calibrator into setup mode. The setup menu is shown in
the Control Display. Choose Setup options with the softkeys below the Control Display.
The RESET (Reset Calibrator) key aborts the Calibrators current operation and changes it to the
power-up default condition, except when it is used by remote control.
The CE (Clear Entry) key clears a partially-completed keypad entry from the Control Display. If
there is a partially-completed entry when is pushed, the output is unaffected.
The EDIT FIELD (Edit Output Display Field) key and its left/right arrow keys provide step
adjustment of the output signals. If any of these keys are pushed or the knob is rotated, a digit on
the Output Display is highlighted and the output increments or decrements as the knob is rotated.
If a digit goes past 0 or 9, the digit to its left or right is carried. An error shows on the Control
Display. The difference between the original (reference) output and the new output is shown.
The and keys adjust the magnitude of changes by moving the highlighted digit. lets
you move from voltage or current to frequency and back. In practice, for voltage and current
outputs, the knob and arrow keys are used to adjust output until the UUT reads correctly. The error
display then shows the UUT deviation from the reference.

The power switch turns on and off Calibrator power. The switch is a latching push-push type. When
the switch is latched in, Calibrator power is on.
The ZERO CAL key lets you do an ohms zero or a full-zero calibration.
The DIV (Divide) key immediately changes the output to 1/10th reference value (not necessarily the
present output value) if the value is in performance limits. In the SCOPE mode, changes the
output to the next lower range.
The MULT (Multiply) key immediately changes the output to 10X the reference value (not
necessarily the present output value) if the value is in performance limits. This key sets the
Calibrator to standby if this change is from <33 V. In the SCOPE mode, changes the output to
the next higher range.
The MEAS TC (Measure Thermocouple) key starts the TC (Thermocouple) input connection and
makes the Calibrator calculate a temperature derived from the voltage that is at the input.
Output Units Keys
The output units keys choose the function of the Calibrator. Some keys have a secondary unit if

The ENTER key loads a newly-entered output value, shown on the Control Display, into the
Calibrator, which shows on the Output Display. The new value can come from the numeric keypad.
If you push without identifying the units for the entry, in most cases the Calibrator keeps the
units that were last used. This lets you, for example, enter 1 mV, and then later enter 10 to get 10 V.
(The "V" units were saved from the last entry, but not the multiplier, "m".) In the error (edit) mode,
with no value puts the output to the value of the reference.

The SHIFT key selects an alternative function of the units key and alternative multipliers of the
multiplier keys. These alternative selections are named with small letters in the upper-left hand
corner of the keys.
Numeric Keypad
Use to record the digits of the output amplitude and frequency. The correct sequence to record a
value is to push the digits of the output value, a multiplier key (if necessary), an output units key,
and then . For example, to obtain an output of 20 mV, you would push this sequence of
keys: . Push to enable the output. If you push a digit key once the entry
field is full, or push the decimal point key more than once in a single number, the beeper will
sound.
The (Polarity) key changes the polarity of the output for dc voltage or dc current functions.
Push the key and then to toggle the output polarity.
The SCOPE TRIG (Scope Trigger) BNC connector is used to trigger the oscilloscope during
oscilloscope calibration. This is active only when an oscilloscope option is installed.
The SCOPE OUT (Oscilloscope) A BNC connector is used for outputs during oscilloscope
calibration. This is active only when an oscilloscope calibration option is installed.

The TC (Thermocouple) minijackis used for thermocouple simulation during thermometer
calibration, and thermocouple measurements. You must use the correct thermocouple wire and
plug when you use this connector. For example, if you will simulate a type-K thermocouple, use
type-K thermocouple wire and type-K plug to make connections.
The 20A terminal is the source of current output when the 20 A range is selected (3 A to 20 A).
The AUX (Auxiliary Output) terminals are used for ac and dc current outputs, the second voltage
output in dual-voltage modes, and ohms sense for 2-wire and 4-wire compensated resistance and
capacitance measurements, and RTD simulation.
The NORMAL (Normal Output) terminals are used to source ac and dc voltage, ohms, and
capacitance. The terminals are also used for Resistance Temperature Detector (RTD) simulation.

Introduction
To prevent possible electrical shock, fire, or personal injury, do
not make connections to the output terminals when voltage is
present. Standby mode is not sufficient to prevent shock
hazard because could be pushed accidently. Push
and make sure that the Calibrator is in standby before you
make connections to the output terminals.
This chapter gives instructions to operate the Calibrator from the front panel. For a
description of front-panel controls, displays, and terminals, see Chapter 3, “Features”.
Turn on the Calibrator
When the Calibrator is on, the initial display is “Starting Up...” (see below) and it
completes a self-test routine. If a self-test fails, the Control Display shows an error code.
For a description of error codes, see Chapter 7, “Maintenance.”
Warning

Warm up the Calibrator
Use the Softkeys
When you turn on the Calibrator, let it warm up for 30 minutes to let the internal
components become stable. Specifications given in Chapter 1 apply to a Calibrator that
has completed its warm-up procedure.
If you turn off the Calibrator after warm up and then on again, give it a warm-up period of
no less than two times the length of time it was turned off (maximum of 30 minutes). For
example, if the Calibrator is turned off for 10 minutes and then on again, give it a warm-up
period of no less than 20 minutes.
The five keys to the right of are called softkeys. Softkey functions come from the
name that shows directly above the key in the Control Display. Push a softkey to change
a value or cause a submenu with new selections to be shown on the Control Display.
Softkey menus are put in different levels, as given in the “Softkey Menu Tree” section in
Chapter 3. You can move back through the menu selections with . Although
will return you to the top-level menu, it will also reset all volatile settings and return the
Calibrator to 0 V dc in the standby mode. Use as your main navigation tool to move
through the menu levels.
Use the Setup Menu
Push the front-panel key to access various operations and changeable parameters.
Most parameters are nonvolatile. This means they will be stored during reset or when you
turn off the power. Chapter 3 shows a map of the menu tree, the parameters, and has a
table of factory-default values.
When you push from power-up, the display changes to:
This is the primary instrument setup menu. The list below tells you about the submenus
that available through each softkey and tells you where you can find more information in
the manuals.
• CAL (Calibration)
Opens the calibration menu. You use softkeys in this menu to see the calibration
dates, print a calibration report, calibrate, and to do the Zero calibration routine. Zero
calibration is given in this chapter.

• INSTMT SETUP (Instrument Setup)
Lets you change the power-up or reset default setting for different instrument
parameters. Many of the same parameters in this menu can be changed during
operation, but the changes you make during operation are volatile. Change them here
to makes them nonvolatile. To set the Calibrator to its factory defaults, use the
Format NV Memory menu in the UTILITY FUNCTNS menu.
• UTILITY FUNCTNS (Utility Functions)
Lets you to start self-tests, format the nonvolatile memory (set the factory defaults),

These features are given in the “Utilities Function Menu” section of this chapter.
Use the Instrument Setup Menu
The softkeys in the instrument setup menu (accessed by pressing INSTMT SETUP
softkey in the Setup Menu) are shown below.
The list below gives submenus accessed by each softkey.
• OTHER SETUP
Opens a menu that lets you toggle the degree reference between the 1968
International Provisional Temperature Standard (IPTS-68) and the 1990 International
Temperature Standard (ITS-90) (factory default). This is also where you set the
clock, and set the power-up and reset defaults for the SC-600 Oscilloscope
Calibration Option Overload test safety timeout function (OVLD T), and shown error
units. You can also configure the Calibrator for best operation with a 50 Hz line
frequency.
• OUTPUT SETUP
Opens a menu to change the power-up and reset defaults for current and voltage
output limits, default thermocouple and RTD types, set the phase reference, internal
or external phase reference source, and impedance for dBm display.
• DISPLAY SETUP
Opens submenus to set the intensity and contrast of the Control and Output
Displays.
• REMOTE SETUP
Lets you change the configuration of the two RS-232 ports, SERIAL 1 FROM HOST
and SERIAL 2 TO UUT, and IEEE-488 General Purpose Interface Bus (GPIB). (See

It is necessary that the rear-panel CALIBRATION switch to be in the ENABLE position
for the ALL and CAL softkeys in this menu. The nonvolatile memory has calibration
constants and dates, setup parameters, and the user report string. With calibration
constants, factory defaults are the same for all calibrators. They are not the calibration
constants received when the Calibrator was calibrated by the factory before shipment.

Reset the Calibrator 4
The softkeys are:
• ALL
replaces all contents of the EEPROM with factory defaults. This is used by service
personnel after they replace the EEPROM, for example. It is not typically necessary.
• CAL
replaces all calibration constants with factory defaults but keeps the setup parameters
unchanged. This is also not typically necessary.
• SETUP
replaces the setup parameters with factory defaults (Table 3-3) but keeps the
calibration unchanged. You do not have to break the calibration seal for this
operation. Remote commands can also change the setup parameters. (See these
commands in Chapter 6: SRQSTR, SPLSTR, *PUD, SP_SET, UUT_SET,
TEMP_STD, DATEFMT, RTD_TYPE_D, TC_TYPE_D, LIMIT.)
Reset the Calibrator
When you use front panel-operation (not remote operation), you can put the Calibrator to
the power-up condition with , except after an error message, which is cleared by a
push of the blue softkey.
Push to:
• Put the Calibrator into the power-up condition: 0 V dc, standby, 330 mV range and
all OUTPUT SETUP menus set to their most recent default values.
• Erases the stored values for limits and error mode reference.
Zero the Calibrator
When you zero the Calibrator, the Calibrator recalibrates internal circuitry, most notably
dc offsets in all ranges of operation. Zero the Calibrator each seven days to make sure the
Calibrator outputs are not more or less than the limits of its specification, or when the
Calibrator ambient temperature changes by more than 5 °C. The tightest ohms
specifications are kept by a zero calibration each 12 hours within ±1 °C of use. The
Calibrator shows a message when it is necessary to zero the Calibrator. To zero the
Calibrator is very important when your calibration workload has 1 mΩ or 1 μV
resolution, and when there has been a significant temperature change in the Calibrator
work environment. There are two functions that zero the Calibrator: total instrument zero
(ZERO) and ohms-only zero (OHMS ZERO).
Complete these procedures to zero the Calibrator.

to reset the Calibrator. For a complete zero calibration, a short circuit that can
pass 20 A must to be applied between the 20A and AUX LO terminals.
Operate and Standby Modes
When the OPERATE annunciator is illuminated and OPR is shown, the output value and
function shown on the Output Display is live at the selected terminals. When STBY is
shown in the Output Display, most of the Calibrator outputs are open-circuited. The
front-panel thermocouple (TC) terminals are not open-circuited. To start the operate
mode, push . To put the Calibrator in standby, push .

If the Calibrator operates and these things occur, the Calibrator automatically goes to the
standby mode:
• is pushed.
• A voltage ≥33 V is selected when the previous output voltage was less than 33 V.
• Output function is changed between ac or dc voltage when the output voltage is

Connect the Calibrator to a UUT 4
• A p-p voltage output (square wave, triangle wave, or truncated sine wave) changes to
rms voltage output ≥33 V (sine wave). For example, if a p-p output of 40 V is
changed to rms output of 40 V by a change to the wave form with the WAVE
softkey, the Calibrator goes to the standby mode.
• The output location for current is changed from AUX to 20 A, or from 20 A to
AUX .
• An overload condition occurs.
Connect the Calibrator to a UUT
Warning
To prevent possible electrical shock, fire, or personal injury, do
not make connections to the output terminals when voltage is
present. Standby mode is not sufficient to prevent shock
hazard because could be pushed accidently. Push
and make sure that the Calibrator is in standby before you
make connections to the output terminals.
The NORMAL (HI and LO) outputs are used to source voltages, resistances, capacitance,
and simulate resistance temperature detector (RTD) outputs. The LO terminal connects to
the analog signal ground in the guard shield. This signal line can or cannot be connected
to the chassis ground. This depends on how is set. See “When to Use EARTH” in
this chapter for more about these internal connections.
The AUX (HI and LO) outputs source current and low voltages in the dual voltage
function. These outputs are also used for four-wire or remote sensing in the resistance,
capacitance, and RTD functions.
When an oscilloscope calibration option is installed, the SCOPE OUT BNC connectors
and TRIG give signals for oscilloscope calibration.
Use the TC socket to measure thermocouples and to supply simulated thermocouple
outputs.
Recommended Cable and Connector Types
Warning
To prevent possible electrical shock, fire, or personal injury:
• Do not use test leads if they are damaged. Examine the test
leads for damaged insulation, exposed metal, or if the wear
indicator shows. Check test lead continuity.
• Use only cables with correct voltage ratings.
• Connect the common test lead before the live test lead and
remove the live test lead before the common test lead.
• Use only the mains power cord and connector approved for
the voltage and plug configuration in your country and rated
for the Product.

Operators Manual
When to Use EARTH
• Properly terminate the sense leads to prevent exposure to
hazardous voltages on the sense terminals. The voltage
sense terminals are at output voltage when the two-wire
function is set.
• Do not touch exposed metal on banana plugs, they can have
voltages that could cause death.
• Do not use a two-conductor mains power cord unless you
install a protective ground wire to the Product ground
terminal before you operate the Product.
• Make sure that the Product is grounded before use.
Cables to the Calibrator are connected to the NORMAL and AUX terminals. To prevent
errors caused by thermal voltages (thermal emfs), use connectors and conductors made of
copper or materials that supply small thermal emfs when connected to copper. Do not use
nickel-plated connectors. For best results use the Fluke Model 5440A-7002 Low Thermal
EMF Test Leads, which are made of well-insulated copper wire and tellurium copper
connectors. See Chapter 8, “Accessories.”

Front-Panel Operation
Connect the Calibrator to a UUT 4
The Calibrator front panel NORMAL LO terminal is typically isolated from earth
(chassis) ground. When it is necessary to make a connection from the NORMAL LO
terminal and earth ground, push the key, this lights the key annunciator. When the
earth key is pushed, the NORMAL LO terminal is connected to earth ground through
approximately 30 Ω.
To prevent ground loops and noise you must have only one earth ground-to-LO terminal
connection in the system. Typically you make all signal ground connections at the UUT
and make sure that the annunciator is off. In most cases, is on only for ac and
dc volts where the UUT is isolated from earth ground. There must be a safety ground for
the Calibrator. See “Connect to Line Power” in Chapter 2. When the sourced output is
live, a softkey LO is shown, which lets you tie or open an internal connection from the
NORMAL LO terminal to the AUX LO terminal. When tied and is on, then both
LO terminals are tied to chassis ground.
Four-Wire versus Two-Wire Connections
Four-wire and two-wire connections are methods to connect the Calibrator to the UUT to
cancel out test lead resistance to make sure the highest precision of the calibration output.
Figures 4-2 through 4-4 show the connection configurations for resistance. Figures 4-5
and 4-6 show connection configurations for capacitance. The external-sensing function of
the four- and two-wire compensated connections gives increased precision for resistance
values less than 110 kΩ and capacitance values 110 nF and above. A part of the
Calibrator output setup for resistance and capacitance includes selections for four-wire
compensation (COMP 4-wire), two-wire compensation (COMP 2-wire) and two-wire no
compensation (COMP off). (See “Set Resistance Output” and “Set Capacitance Output”
in this chapter.) Note that compensated connections for capacitance are to compensate for
lead and internal resistances, not for lead and internal capacitances.
Four-Wire Connection
The four-wire connection is typical for calibration of laboratory measurement equipment.
Increased precision is supplied for resistance values less than 110 kΩ. For other values,
the lead resistances do not degrade the calibration and the Calibrator changes the
compensation to off (COMP off).
Two-Wire Compensation
The two-wire connection is typical for calibration of precision handheld Digital
Multimeters (DMMs) with a two-wire input. Increased precision is supplied for resistance
values less than 110 kΩ and capacitance values 110 nF and above. For other values, the
Calibrator changes the compensation to off (COMP off).
Compensation Off
Compensation off is a typical connection for calibration of handheld analog meters or
DMMs with a two-wire input. This connection is used for all values of resistance and
capacitance and is typically selected when more precision is not necessary for the analog
meter or DMM level of accuracy. This is the default condition when an ohms or
capacitance output is made after an output that was not ohms or capacitance.
4-11
Page 86
5502A
Operators Manual
Cable Connections Instructions
Table 4-1 shows the figure names for each type of connection from a UUT to the
Calibrator.
When you calibrate Resistance Temperature Detectors (RTDs) with the three-terminal
connection shown in Figure 4-9, make sure the test leads have with resistances to cancel
errors from lead resistance. This can be done, for example, with three test leads of the
same length and with the same connector styles.
When you calibrate thermocouples, it is especially important to use the correct hookup
wire and miniconnector between the Calibrator front panel TC terminal and the UUT.
You must use the correct thermocouple wire and miniconnectors for the type of
thermocouple. For example, if you simulate a temperature output for a type K
thermocouple, use type K thermocouple wire and type K miniplugs for the hookup.
To connect the Calibrator to a UUT:
1. If the Calibrator is turned on, push to remove the output from the Calibrator
terminals.
2. Select the correct figure from Table 4-1 to make the connections to the UUT.
3. For capacitance outputs, connect the test leads to the UUT to null out stray
capacitance. Put the cables (but do not connect them) to the Calibrator on a
non-conductive surface. Null out the indication on the UUT with “rel,”
“offset,” or “null,” (use the necessary method), and then connect the test leads
to the Calibrator.

RMS Versus p-p Amplitude
The Calibrator ranges for sinusoidal ac functions are specified in rms (root-mean-square,
the effective value of the wave form). For example, 1.0 to 32.999 mV, 33 to 329.999 mV,
0.33 to 3.29999 V, etc. The sine wave outputs are in rms, while the triangle wave, square
wave, and truncated sine wave outputs are in p-p. The relationship between p-p and rms
for the non-sine wave types are:
• Square wave p-p x 0.5000000 = rms
• Triangle wave p-p x 0.2886751 = rms
• Truncated Sine wave p-p x 0.2165063 = rms
While the ac function ranges are compatible for sine waves, the rms content of the
other waveforms is less apparent. This quality leads to subtle Calibrator range changes.
For example, if you record a sine wave voltage of 6 V (rms assumed), the selected
range is 3.3 to 32.9999 V. If you then use the softkeys to change from a sine wave to a
triangle wave, for example, the display changes from 6 V rms to 6 V p-p. This
translates to 6 V p-p x 0.2886751 = 1.73205 V rms, and the range switches to 0.33 to
3.29999 V. The Output Display shows the range change because the sine wave voltage
is shown as 6.0000, the resolution for the 3.3 to 32.9999 V range, while the triangle
wave is shown as 6.00000, the resolution for the 0.33 to 3.29999 V range.
You must know the range in operation to record the correct values for voltage offset
because the maximum offsets are specified to the range. For example, the maximum peak
signal for the 3.3 to 32.9999 V range is 55 V while the maximum peak signal for the 0.33
to 3.29999 V range is 8 V. This means in the example above, the 6 V rms sine wave
could have offsets applied to a maximum peak signal of 55 V because the current range is
3.3 to 32.9999 V, while the 6 V p-p triangle wave could have offsets applied to a
maximum peak signal of 8 V because the current range is 0.93 to 9.29999 V. See
“Specifications” in Chapter 1 and “Record a DC Offset” in this chapter for more about dc
offset voltages.

Auto Range Versus Locked Range
A softkey is supplied to toggle between the ranging methods auto or locked. This feature
is available only for single-output dc volts and dc current outputs.
When you select auto (the default), the Calibrator automatically selects the range that
gives the best output resolution. When you select locked, the Calibrator locks the selected
range and will not change ranges when you edit the output, or record new outputs. Values
lower or higher than the locked range are not permitted. The locked selection is typically
made to prevent range changes that can cause a small perturbation in the output, for
example, when you measure the linearity of a given multimeter range.
Set Output
To set the Calibrator output, push the keys for the necessary values and then push a units
key to identify which of the volts, amps, hertz, etc., that the values are for. The control
display shows the value and units you select as you type them into the Calibrator. When
you are satisfied with the value and units, push . If the output display shows
STBY, push to output the selection. A small “u” (unsettled) in the Output Display
shows that the Calibrators internal circuitry must become stable.
For example, to set the output to 10 V dc, push:

A softkey name for range is shown on the Control Display in the dc voltage function:
Range (Operating Range) selects autorange (auto) or lock (locked) for the current
range. When auto (the default) is selected, the Calibrator automatically selects the
range that gives the best output resolution. When locked is selected, the Calibrator
will not change ranges when you edit the output. The locked selection is typically
made to prevent range changes that can cause a small agitation in the output, for
example, when you measure the linearity of a given multimeter range.
Set AC Voltage Output
You can select an ac voltage output in volts or as a power output in dBm, where dBm is
10 log (Pout/.001), where Pout is shown in watts. The output range is 1 mV to 1000 V.
When you select dBm outputs, the Calibrator calculates dBm at a selected impedance
level. For this instance, the formula is:
20 log(V) - 10 log(Impedance * .001) = dBm.
Do this procedure to set an ac voltage output at the front panel NORMAL terminals. If
you make an entry error, push to erase the display, then record the value again.
To prevent damage to the UUT, makes sure the applied voltage to
the UUT is not larger than the rating of the UUT insulation and the

Software names are shown on the Control Display in the ac voltage function, in
reference to which waveform is selected: DUTY, OFFSET and WAVE.
• DUTY (Duty Cycle) When the square wave is selected, DUTY shows and lets you
change the duty cycle of the square wave. The range is 1.00 % to 99.00 %. The
default is 50.00 %. The duty cycle must be 50.00 % if it is necessary to record an
OFFSET (see below).
• OFFSET (Voltage Offset) shows when the necessary output is less than 33 V (sine
waves), 65 V (square waves) or 93 V (triangle waves and truncated sine waves). This
softkey lets you to add a positive or negative dc offset voltage to the ac output signal.
See “Record a DC Offset” in this chapter for more information. When a voltage
output is shown in dBm, voltage offset is not available. You can record an offset for
a square wave output only when the duty cycle is 50.00 % (see DUTY above).
• WAVE (Waveform) lets you select one of four different types of waveforms: sine
wave, triangle wave, square wave, and truncated sine wave. (See “Waveform Types”
in this chapter). When a non-sinusoidal waveform is selected, the Output Display
shows Pp (p-p). Output in dBm is sine wave only.
