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.

• Use Product-approved measurement category (CAT), voltage, and amperage rated accessories (probes,
test leads, and adapters) for all 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.

Unsafe Voltage
To alert you to the presence of a potentially hazardous
voltage, when the Tester detects a voltage ≥ 30 V in
insulation test, ≥2 V in resistance, or a voltage overload
(), the symbol is displayed.
Battery Saver
(Sleep Mode)
The Tester enters the “Sleep mode” and blanks the
display if there is no function change or button press for
10 minutes. This is done to conserve battery power. To
resume operation, turn the rotary switch to OFF and then
turn to any function.
The 10-minute timer is disabled during any insulation
resistance or earth bond resistance measurement. The
time period starts immediately following any
measurement.
Rotary Switch Positions
Turn the Tester on by selecting any measurement
function. The Tester presents a standard display for that
function (range, measurement units, modifiers, etc.). Use
the blue button to select any rotary switch alternate
functions (labelled with blue letters). Rotary switch
selections are shown in Figure 1 and described in Table 2.

Measuring Earth-Bond Resistance
Resistance tests should only be performed on
de-energized circuits. Check the fuse before testing. See
Testing the Fuse later in this manual. Connecting to an
energized circuit while the test is active will blow the fuse.
Note
Measurements can be adversely affected by
impedances of additional operating circuits
connected in parallel or by transient currents.
To measure resistance:
1. Insert test probes in the Ω and
COM input terminals.
See Figure 6.
2. Turn the rotary switch to the position.
3. Short the ends of the probes together, press the blue
button and wait until dashes appear on the display.
The Tester measures the probe resistance, stores the
reading in memory, and subtracts it from readings.
The probe resistance reading is saved even when the
Tester is turned off. If the probe resistance is >2 Ω,
the resistance will not be saved.
4. Connect the probes to the circuit to be measured. The
Tester automatically detects if the circuit is energized.

Measuring Insulation Resistance
Insulation tests should only be performed on de-energized
circuits. To measure insulation resistance set up the
Tester as shown in Figure 7 and follow the steps below:
1. Insert test probes in the V and COM input terminals.
2. Turn the rotary switch to the desired test voltage.
3. Connect the probes to the circuit to be measured. The
Tester automatically detects if the circuit is energized.
• The primary display shows until you press
and a valid insulation resistance reading
is obtained.
• The high voltage symbol () along with a primary
display of >30 V warns if voltage more than 30 V
ac or dc is present. In this condition, the test is
inhibited. Disconnect the Tester and remove
power before proceeding.
4. Push and hold to start the test. The secondary
display shows the test voltage applied to the circuit
under test. The high voltage symbol () along with a
primary display showing the resistance in MΩ or GΩ
appears. The
icon appears on the lower portion of
the display until is released.
When resistance is higher than the maximum display
range, the Tester displays the symbol and the
maximum resistance for the range.
5. Keep the probes on the test points and release the
button. The circuit under test then discharges
through the Tester. The resistance reading appears
on the primary display until a new test is started or a
different function or range is selected or >30 V is
detected.

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.
