Insulation Testers

Introduction

The Fluke model 1507 and model 1503 are
battery-powered insulation testers (hereafter, "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 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 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

Users Manual

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 XWWarning identifies hazardous conditions and actions that could cause bodily harm or death.

A XWCaution identifies conditions and actions that could damage the Tester, the equipment under test, or cause
permanent loss of data.

XWWarning

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.

Insulation Testers
Safety Information

• 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.

• Comply with local and national safety requirements when working in hazardous locations.

• Use proper protective equipment, as required by local or national authorities when working in

hazardous areas.

• Avoid working alone.

• Use only the replacement fuse specified or the protection may be impaired.

• Check the test leads for continuity before use. Do not use if the readings are high or noisy.

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
(OL), the Z 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. The
Tester comes out of Sleep mode when a key is pressed or
when the rotary switch is turned.

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

2. Turn the rotary switch to the O 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.

Measuring Polarization Index and
Dielectric Absorption Ratios (Model

1507)

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.

2. Turn the rotary switch to the desired test voltage
position.

3. Press the E button to select polarization index or
dielectric absorption ratio.

lower portion of the display until the test is finished.

When the test is completed, the PI or DAR value is

test will automatically be discharged through the
Tester. If either value used to calculate PI or DAR
was greater than the maximum display range, or the
1-minute value was greater than 5000 MΩ, the
primary display will show Err.

• When resistance is higher than the maximum

display range, the Tester displays the > symbol
and the maximum resistance for the range.

• To interrupt a PI or DAR test before it is
completed, momentarily press T. When you
release T, the circuit under test will
automatically be discharged through the Tester.
