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

Introduction
The Fluke model 1507 and model 1503 are
battery-powered insulation testers (the Tester). Although
this manual describes the operation of both Models 1507
and 1503, all illustrations and examples assume use of
model 1507.
These Testers meet IEC 61010 standards. The
IEC 61010-2-030 standard defines three measurement
categories (CAT II to IV) based on the magnitude of
danger from transient impulses. CAT IV Testers are
designed to protect against transients from the primary
supply level (overhead or underground utility service).
The Tester measures or tests the following:
• AC / DC Voltage
• Earth-Bond Resistance
• Insulation Resistance

Safety Information
Use the Tester only as specified in this manual. Otherwise, the protection provided by the Tester may be impaired. See
Table 1 for a list of symbols used on the Tester and 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.
XW
Warnings
To prevent possible electrical shock, fire, or personal injury:
• Read all safety information before you use the Product.
• Do not alter the Product and use only as specified, or the protection supplied by the Product can be
compromised.
• Carefully read all instructions.
• Do not use the Product around explosive gas, vapor, or in damp or wet environments.
• Comply with local and national safety codes. Use personal protective equipment (approved rubber
gloves, face protection, and flame-resistant clothes) to prevent shock and arc blast injury where
hazardous live conductors are exposed.
• Do not work alone.
• Examine the case before you use the Product. Look for cracks or missing plastic. Carefully look at the
insulation around the terminals.
• Do not use the Product if it is altered or damaged.
• 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.
• Do not touch voltages >30 V ac rms, 42 V ac peak, or 60 V dc.
• Do not apply more than the rated voltage, between the terminals or between each terminal and earth ground.
• Use the correct terminals, function, and range for measurements.
•Do not exceed the Measurement Category (CAT) rating of the lowest rated individual component of a
Product, probe, or accessory.
•Do not use in CAT III or CAT IV environments without the protective cap installed on test probe. The
protective cap decreases the exposed probe metal to <4 mm. This decreases the possibility of arc flash
from short circuits.
• Remove all probes, test leads, and accessories that are not necessary for the measurement.
• Keep fingers behind the finger guards on the probes.
• Measure a known voltage first to make sure that the Product operates correctly.
• Always de-energize circuits before you do resistance tests.
• Replace a blown fuse with exact replacement only for continued protection against arc flash.
• Remove the batteries if the Product is not used for an extended period of time, or if stored in
temperatures above 50 °C. If the batteries are not removed, battery leakage may result.
• Replace the batteries when the low battery indicator shows to prevent incorrect measurements.
• Remove all probes, test leads, and accessories before the battery door is opened.
• Replace all batteries with fresh batteries of the same manufacturer and type to prevent battery leakage.
• Repair the Product before use if the battery leaks. Battery leakage may create a shock hazard or
damage the Product.
• The battery door must be closed and locked before you operate the Product.
• Do not operate the Product with covers removed or the case open. Hazardous voltage exposure is
possible.
•Have an approved technician repair the Product.

Polarization Index (PI) is the ratio of the 10-minute
insulation resistance to the 1 minute insulation resistance.
Dielectric Absorption Ratio (DAR) is the ratio of the
1-minute insulation resistance to the 30 second insulation
resistance.
Insulation tests should only be performed on de-energized
circuits. To measure the polarization index or dielectric
absorption ratio:
1. Insert test probes in the
INSULATION and COM input
terminals.
Note
Because of the time required to perform the PI
and DAR tests, use of test clips is recommended.
