Insulation Multimeters
Introduction

Introduction
The Fluke Model 1587, and Model 1577 are battery-powered, true-rms insulation
multimeters (hereafter, Meter or UUT) with a 6000-count and a 3 ¾ digit display.
Although this manual contains calibration information for Models 1587 and 1577, all
illustrations and examples assume use of the Model 1587. Table 1 provides a
description of all the symbols used in this manual.
The Meter meets CAT III and 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 III meters are designed to protect against transients in
fixed equipment installations at the distribution level; CAT IV meters are designed to
protect against transients from the primary supply level (overhead or underground
utility service).

Warning
To avoid possible electric shock or personal injury, follow these guidelines:
•
Use the Meter only as specified in this manual or the protection provided by the
Meter might be impaired.
•
Do not use the Meter or test leads if they appear damaged, or if the Meter is not
operating properly. If in doubt, have the Meter serviced.
•
Always use the proper terminal, switch position, and range for measurements
before connecting the Meter to circuit under test.
•
Verify that the Meter is operational by measuring a known voltage.
•
Do not apply more than the rated voltage as marked on the Meter, 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 Meter around explosive gas or vapor.
•
When using the test leads, keep your fingers behind the finger guards.
•
Remove test leads from the Meter before opening the Meter case or battery door.
Never operate the Meter with the back case 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.
