Introduction
 Warning
If the 5080A Calibrator is operated in a manner not specified by
this manual or other documentation provided by Fluke, the
protection provided by the Calibrator may be impaired.
The 5080A Calibrator is a fully programmable precision source of the following:
• DC voltage from 0 V to ±1020 V.
• AC voltage from 1 mV to 1020 V, with output from 45 Hz to 1 kHz.
• AC current from 29 μA to 20.5 A, with variable frequency limits.
• DC current from 0 to ±20.5 A.
• Discrete resistance values from a short circuit to 190 MΩ.
Features of the 5080A Calibrator include the following:
• Automatic meter error calculation.
• and keys that change the output value to pre-determined cardinal values for
various functions.
• Programmable entry limits that prevent entering invalid amounts.
• Simultaneous output of voltage and current, up to an equivalent of 20.9 kVA.
• Simultaneous output of two voltages.
• Variable phase signal output.
• EIA Standard RS-232 serial data interface to print, show, or transfer internally stored
calibration constants, and for remote control of the 5080A.
Safety Information
This Calibrator complies with:
• ANSI/ISA-61010-1 (82.02.01)
• CAN/CSA C22.2 No. 61010-1-04
• ANSI/UL 61010-1:2004
• EN 61010-1:2001
In this manual, a Warning identifies conditions and procedures that are dangerous to the
user. A Caution identifies conditions and procedures that can cause damage to the
Product or the equipment under test.

Do not dispose of this product as
unsorted municipal waste. Go to
Fluke’s website for recycling
information.
This manual contains information, warnings, and cautions that must be followed to
ensure safe operation and to maintain the Calibrator in a safe condition.
 Warning
To prevent possible electric shock or personal injury, follow
these guidelines:
• Use this Calibrator only as specified in this manual or the
protection provided by the Calibrator might be impaired.
• Do not apply more than 264 V ac rms between the supply
conductors or between either supply conductor and ground.
• Use caution when working with voltages above 30 V ac rms,
42 V peak, or 60 V dc. These voltages pose a shock hazard.
• Ensure the Calibrator is in STANDBY by pressing the RESET
key before disconnecting test leads.
• Ensure the grounding conductor in the power cord is
properly connected to a protective ground. The output
terminals are clamped to the earth referenced chassis and
rely on the protective earth bond to limit accessible voltage
to the operator. Disruption of the protective earth could
place lethal voltage onto the chassis of the Calibrator due to
abnormal output terminal configuration or mains transient
condition.
• Use only the replacement fuses specified by the manual.
• Do not position the Calibrator such that the power cord
cannot be accessed in the event of an emergency. In the
event that customer installation interferes with access to the
power cord, a suitable power disconnection switch shall be
provided by the customer.
• Use only the power cord and connector appropriate for the
voltage and plug configuration in your country.

Calibrator
Instruction Manuals

• Use only a power cord that is in good condition. Refer
power cord and connector changes to qualified service
personnel.
• Do not operate the Calibrator in an atmosphere of explosive
gases.
• Verify the voltage applied to the unit under test does not
exceed the insulation rating of the UUT and the
interconnecting cables.
• Do not remove the Calibrator cover without first
disconnecting the power cord.
• Do not operate the Calibrator without the cover properly
installed. Access procedures and the warnings for such
procedures are contained in the Service Manual. Service
procedures are for qualified service personnel only.
• Do not use the Calibrator if it has damage or operates
abnormally. Refer all questions of proper Calibrator
operation to qualified service personnel.
Caution
To avoid damage to the Calibrator, do not apply voltage in
excess of the marked rating to any terminal.

General Maintenance
This section explains how to do routine maintenance on a 5080A Calibrator. These tasks
include:
• How to Replace the fuses
• How to Clean the air filter
• How to Clean the External Surfaces
How to Replace the Line Fuse
Caution
To prevent possible damage to the instrument, verify the
correct fuse is installed for the selected line voltage setting
100 V and 120 V, use 5.0 A/250 V time delay (slow blow); 220 V
and 240 V, use 2.5 A/250 V time delay (slow blow).
You can access the line power fuse on the rear panel. The fuse rating is 5 A/250 V slow
blow fuse for 100 V/120 V line voltage; 2.5 A/250 V slow blow fuse for 220 V/240 V
line voltage.
To examine or replace the fuse, refer to Figure 1 and continue as follows:
1. Disconnect line power.

How to Replace the Current Fuses
The two Calibrator current outputs have fuse protection. If the Calibrator cannot source
current, one or both of the current fuses can be blown.
 Warning
To prevent electric shock, turn the Calibrator off and remove
the mains power cord. Stop for two minutes to let the power
assemblies discharge before you open the fuse door.
To replace the current output fuses:
1. Turn the Calibrator off and remove the power cord. Stop for two minutes to let the
power assemblies discharge.
2. Turn the Calibrator over.
3. Remove the two screws that hold the fuse compartment cover in place and remove
the cover as shown in Figure 2.

How to Clean the Air Filter
Warning
To prevent risk of injury, do not operate or power the 5080A
calibrator without the fan filter in place.
Caution
Damage can occur when the Calibrator becomes too hot if the
area around the fan is restricted, the intake air is too warm, or
the filter becomes clogged.
The air filter must be removed and cleaned at 30 day intervals, or more frequently if the
calibrator is operated in a dusty environment. You access the air filter from the rear panel
of the calibrator.
To clean the air filter, refer to Figure 3 and continue as follows:
1. Turn the power off and let the fan come to a stop.
2. Disconnect the ac line cord.
3. Remove the filter element.
a. Hold the top and bottom of the air filter frame.
b. Squeeze the edges of the frame towards each other to disengage the filter tabs
from the slots in the Calibrator.
c. Pull the filter frame straight out from the Calibrator.
4. Clean the filter element,
a. Clean the filter element in soapy water.
b. Flush the filter element.
c. Shake out the water and let the filter element dry before you install it.
5. Do the filter removal steps in reverse order to install the filter element.

How to Verify the Main Calibrator
Use Tables 6 through 16 to make sure the 5080A operates to its specifications. The tables
are for approved metrology personnel who have access to a standards laboratory that has
equipment that can test calibration equipment of this level of accuracy. The tables show
the recommended test points and the upper and lower limits for each point. The limits
calculation is the 90-day specification added to or subtract from the output value. There is
no built-in factor for measurement uncertainty.
