1587/1577
Insulation Multimeters
Introduction
The Fluke Model 1587, and Model 1577 are
battery-powered, true-RMS insulation multimeters
(hereafter "the Meter") with a 6000-count and a 3 ¾ digit
display. Although this manual describes the operation of
both Models 1587 and 1577, all illustrations and
examples assume use of Model 1587.
These meters meet 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).
The Meter measures or tests the following:
• AC / DC voltage and
current
• Diodes (Model 1587)
• Resistance • Continuity
• Voltage and current
frequency
• Capacitance (Model
1587)
• Temperature (Model
1587)
• Insulation testing
