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.

Introduction

The Fluke Models 1503, 1507, and 1508 are battery-powered insulation testers (hereafter,
Tester or UUT). These Testers meet CAT IV IEC 61010 standards. The IEC 61010
standard defines four measurement categories (CAT I to IV) based on the magnitude of
danger from transient impulses. CAT IV Testers protect against transients from the
primary supply level (overhead or underground utility service).

Although this manual contains calibration information for Models 1503, 1507, and 1508,
all illustrations and examples assume use of Model 1507. Table 1 provides a description
of all the symbols used in this manual.

The information provided in this manual includes the following:

• Warnings and Safety Information

• Specifications

• Basic Maintenance

• Performance Test Procedures

• Calibration Adjustment Procedure

• Replaceable Parts and Accessories

The information provided in this manual should only be used by qualified personnel. For
complete operating instructions and additional safety information, refer to the 1507/1503
Insulation Testers Users Manual or the 1508 Insulation Tester Users Manual.

Safety Information

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

• Use the Tester only as specified in this manual or the protection

provided by the Tester might be impaired.

• Do not use the Tester or test leads if they appear damaged, or if the

Tester is not operating properly. If in doubt, have the Tester serviced.

• Always use the proper terminal, switch position, and range for

measurements before connecting Tester to circuit under test.

• Verify the Tester’s operation by measuring a known voltage.

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

between the terminals or between any terminal and earth ground.

• Use caution with voltages above 30 V ac rms, 42 V ac peak, or 60 V dc.

These voltages pose a shock hazard.

• Replace the battery as soon as the low battery indicator (b) appears.

• Disconnect circuit power and discharge all high-voltage capacitors

before testing resistance, continuity, diodes, or capacitance.

• Do not use the Tester around explosive gas or vapor.

• When using the test leads, keep your fingers behind the finger guards.

• Remove test leads from the Tester before opening the Tester case or

battery door. Never operate the Tester with the cover removed or the
battery door open.
