Safety Information
A “XW Warning” statement defines hazardous conditions and actions that could cause bodily harm or
death.
A “W Caution” statement identifies conditions and actions that could damage the Meter or the
equipment under test.
XWRead First: Safety Information
To avoid possible electric shock or personal injury, and to avoid possible
damage to the Meter or the equipment under test, adhere to the following
practices:
• Read the Users Manual before use and follow all safety instructions.
• Use the Meter only as specified in the Users Manual; otherwise, the Meter's
safety features may be impaired.
• Avoid working alone so assistance can be rendered.
• Never use the Meter on a circuit with voltages higher than 600 V or a
frequency higher than 60 Hz fundamental. The Meter may be damaged.
• Never measure ac current while the test leads are inserted into the input
jacks.
• Do not use the Meter or test leads if they look damaged. Inspect the case.
Do not use the Meter if it is damaged. Look for cracks or missing plastic.
Pay particular attention to the insulation around the connectors.
• Use extreme caution when working around bare conductors or bus bars.
Contact with the conductor could result in electric shock.
• Use caution when working with voltages above 60 V dc or 30 V ac rms or
42 V ac peak. Such voltages pose a shock hazard.
• Clean the case with a damp cloth and mild detergent only. Do not use
abrasives or solvents.
• To avoid false readings that can lead to electrical shock and injury, replace
the batteries as soon as the low battery indicator (B) appears.
• Verify the Meter’s operation by measuring a known voltage. Do not use the
Meter if it operates abnormally. Protection may be impaired. When in doubt,
have the Meter serviced.
• Do not hold the Meter anywhere beyond the tactile barrier, see Figure 1.
• Adhere to local and national safety codes. Individual protective equipment
must be used to prevent shock and arc blast injury where hazardous live
conductors are exposed.
• Use the proper terminals, function, and range for your measurements.
• Do not operate the Meter with the case (or part of the case) removed.
• When servicing the Meter, use only specified replacement parts.

Maintenance
XWWarning
To avoid possible electric shock or personal injury, repairs or servicing not
covered in this manual should be performed only by qualified personnel.
Note
When the Meter displays CAL, the unit will lock and no measurements can be made. The Meter must be
sent to a Fluke Service Center for repair.
Cleaning the Meter
XWWarning
To avoid electrical shock, remove any input signals before cleaning.
W Caution
To avoid damaging the Meter, do not use aromatic hydrocarbons or chlorinated
solvents for cleaning. These solutions will react with the plastics used in the
Meter.
Clean the instrument case with a damp cloth and mild detergent.
Replacing the Batteries
XWWarning
To avoid false readings that could lead to possible electric shock or personal
injury, replace the batteries as soon as the low battery indicator (B) appears.
Disconnect the test leads before replacing the batteries.
To replace the batteries, see Figure 1:
1. Turn the rotary switch to “OFF” and remove the test leads from the terminals.
2. Use a Phillips screwdriver to loosen the battery compartment door screw, and remove the door from
the case bottom.
3. Remove the batteries.
4. Replace the batteries with two new AA batteries observing correct polarity.
5. Reattach the battery compartment door to the case bottom and tighten the screw.

Performance Tests
XWWarning
To avoid electric shock, do not perform the performance test procedures unless
the Meter is fully assembled.
The following performance tests verify the complete operation of the Meter and checks the accuracy of
each meter function against the Meter’s specifications. If the Meter fails any part of the test, calibration
adjustment and/or repair is indicated. The Meter must be returned to a Fluke Service Center for repair or
adjustment. See Contacting Fluke.
In the performance tests, the Meter is referred to as the unit under test (UUT).
Preparing for the Performance Test
XWWarning
To avoid possible electric shock or personal injury:
• Do not perform the following procedures unless qualified to do so. Some
procedures involve the use of high voltages.
• Before handling the test connections and in between tests, make sure the
calibrator is in standby mode (STBY).
To prepare for the performance test:
1. Make sure that you have the required equipment, see Table 1.
2. Warm up the calibrator as required by its specifications.
3. Allow the temperature of the UUT to stabilize at room temperature (23 °C ± 5 °C [73 °F ± 9 °F]).

Keypad Test
To test the keypad, turn the Meter on and push each button separately. Each button push will cause the
Meter to beep.
Performance Test Procedure
To test each of the Meter's functions and operating ranges, do the following:
1. Connect the source to the Meter's µA VΩ and COM input jacks.
2. Referring to Table 2, put the Meter into the desired function and range for each test.
3. Apply the indicated output from the source.
4. When using the amp function on the 5520A, make sure LCOMP on the 5520A is ON. See Figure 4 for
current performance test setup.
5. The reading on the Meter display should be within the Meter response limits shown in the table.
6. Repeat steps 1-4 for each function and range in Table 2.
If the Meter fails to perform within the Meter response limits indicated for each test in Table 2, the Meter
must be returned to a Fluke Service Center for repair or calibration adjustment.
