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.

Safety Information

Warning

To avoid possible electric shock or personal injury, follow these
guidelines:

• Do not use the tester if it is damaged. Before you use the

tester, inspect the case. Look for cracks or missing plastic.

Pay particular attention to the insulation surrounding the

connectors.

• Inspect the test leads for damaged insulation or exposed

metal. Check the test leads for continuity. Replace damaged

test leads before you use the tester.

• Do not use the tester if it operates abnormally. Protection

may be impaired. When in doubt, have the tester serviced.

• Do not operate the tester around explosive gas, vapor, or

dust.

• Do not apply more than the rated voltage, as marked on the

tester, between terminals or between any terminal and earth

ground.

• Before use, verify the tester’s operation by measuring a

known voltage.

• When servicing the tester, use only specified replacement

parts.

• If the auto-on light does not come on when the test leads are

shorted together, do not use the tester.

• Use caution when working above 30 V ac rms, 42 V peak, or

60 V dc. Such voltages pose a shock hazard.

• When using the probes, keep your fingers behind the finger

guards on the probes.

• Connect the common test lead before you connect the live

test lead. When you disconnect test leads, disconnect the

live test lead first.

• Do not operate the tester with the battery door or portions of

the cover removed or loosened.

• Before each use, perform the Battery Test to avoid false

readings due to a low battery. Replace the batteries as soon

as the tester fails the Battery Test.

Cleaning the Tester

If the tester requires cleaning, wipe it down with a cloth that is lightly dampened with water or a
mild detergent. Do not use aromatic hydrocarbons, chlorinated solvents, or methanol-based fluids
when wiping down the tester.

Required Equipment

The following equipment is required for performance tests and calibration adjustments:

Warning

To avoid electrical shock or damage to the tester, never allow
water inside the case. To avoid damaging the tester’s case,
never use solvents on the tester.

• Fluke 5500A Multi-Product Calibrator, or equivalent (DC voltage range: 0 to ±1020 V,

AC voltage range: 1 mV to 1020V 10 Hz to 500 kHz, sine)

• Small, insulated, Phillips screwdriver

• Fluke 87 Digital Multimeter (maximum DC voltage = 1000 V ± (0.05%+1), maximum

AC voltage= 1000 V ±(0.7%+2) )

Performance Tests

Use the following procedures to verify the tester’s performance.

Testing the Voltage Function

If the tester fails the voltage test, perform the calibration adjustment described under "Calibration
Adjustment"; then retest all of the voltage functions. If the tester continues to fail, return it to
Fluke for service.

Test the voltage function as follows:

1. Set the calibrator to 199 V dc. Apply this voltage to the tester to verify that the 220 V dc

range LED is on.

2. Apply 190 V dc to the tester. Verify that the tester’s 220 V dc range LED is off.

3. Apply each nominal voltage and frequency as listed in Table 2. Verify that each

corresponding LED turns on.

Calibration Adjustment

Continuity Function Tests

The following tests verify correct operation of the continuity beeper and LED.

1. Set the calibrator to 20 kΩ. Apply the 20 kΩ to the tester and verify that the tester’s beeper

and continuity LED are ON.

2. Set the calibrator to 200 kΩ. Apply the 200 kΩ to the tester and verify that the tester’s beeper

and continuity LED are OFF.

Calibration Adjustment

If the tester fails a voltage test, perform the following calibration adjustment.

1. Verify that the tester’s batteries are good: replace the batterie s if touch ing the leads to geth er

does not turn on the continuity LED.

2. Remove the tester’s battery door and batteries.

3. Remove the two screws that hold the tester’s case together.

4. Remove the top case.

5. Place the tester’s batteries in the battery compartment. Temporarily install the battery door to

hold the batteries in place during calibration.

Tester

WWarning

It is not necessary to remove the two screws that hold the circuit board
in the bottom case; however, if the screws are removed for any reason,

they must be secured with Loctite™ or equivalent when reinstalled to
prevent them from coming loose.

6. Turn the tester on by touching the test leads together.

7. Using a calibrated meter, measure the voltage across the voltage divider with the positive lead

near R4 and the negative lead at the other end of the divider. Refer to Figure 1.

8. Adjust R4 until the voltage across the divider is as follows:

• T3USA = 605 - 615 mV

• T3CAN = 759 - 765 mV

• T3W = 873 - 883 mV

9. Secure R4 with Loctite or equivalent.

10. Reassemble the tester; then perform the voltage test s as given under "Tes ti ng the Vol tag e

Functions".
